The International COVID-19 Data Alliance (ICODA) and the Bill &amp; Melinda Gates Foundation’s Grand Challenges initiative, supported by the COVID-19 Therapeutics Accelerator, are announcing an open funding call for research studies to accelerate knowledge of COVID-19 through data science: Grand Challenges ICODA COVID-19 Data Science.

**NOTE: This opportunity is only open to participants who registered for and attended the 2020 Grand Challenges Annual Meeting (virtual format).

<h2>THE OPPORTUNITY</h2>

The Grand Challenges Annual Meeting - held in <a href="https://grandchallenges.org/annual-meeting" target="_blank">11 countries</a> over the past 15 years and in a virtual format this year - fosters innovation and international collaboration to address the biggest challenges in global health and development. Our goal is to support a global community of problem solvers who work together to set an innovation agenda and do the breakthrough science to deliver on it. Recognizing the pressing global threat of COVID-19, this year's Annual Meeting will focus on how to accelerate transformational innovation for global health crises. The meeting will seek to facilitate collaboration among scientists, decision makers, and policymakers to discover, develop, and deploy the solutions needed to curb the COVID-19 pandemic, mitigate its impact, and prepare for future global health emergencies. Additionally, the meeting will explore how to harness the energy and lessons from COVID-19 to drive continued progress against a broad range of global health and development goals. Besides this Call-to-Action request for proposals from meeting participants, there are three public <a href="https://gcgh.grandchallenges.org/grant-opportunities" target="_blank">grant opportunities</a> addressing global health and development that are opening at the meeting.

<h2>THE CHALLENGE</h2>

The Call-to-Action provides an opportunity for Grand Challenges Annual Meeting participants to take action based on ideas they developed and people they met at the meeting. The <a href="https://gcgh.grandchallenges.org/grants/eyJzb3J0IjoiZGVzY2VuZGluZyIsInNvcnRGaWVsZCI6ImRhdGUiLCJudW1iZXJQZXJQYWdlIjoxMDAsInBhZ2VOdW1iZXIiOjB9/eyJ5ZWFycyI6W10sImNoYWxsZW5nZXMiOlsiMTI5Il0sInRlcm1zIjpbXSwiaW5pdGlhdGl2ZXMiOltdLCJsb2NhdGlvbnMiOltdfQ==" target="_blank">grants awarded</a> for the 2018 and 2019 Call-to-Action were for projects arising &nbsp;from diverse types of opportunities – as noted by applicants in their submitted proposals – to interact at the meeting and to bring together combinations of expertise and perspective to speed the impact of what would otherwise be separate work by individual investigators. We hope that interactive elements at this year's virtual meeting will still provide ways to catalyze collaborative grant applications and that the extra urgency of the meeting's focus this year will inspire projects with a goal and design that will yield a tangible solution to a key problem by the end of the grant.

Funding

Each meeting participant will have one opportunity to apply as the primary applicant for a USD $100,000 grant or a collaborative USD $200,000 grant, both with an 18-month grant duration. Collaborative awards require the participation of at least two meeting participants from different institutions. While restricted to one application as the primary applicant, meeting participants may participate as collaborators in multiple collaborative applications. Priority will be given to new or newly expanded collaborations, rather than to existing partners seeking new funding.

We will give highest priority to proposed projects that:

<ul>
	<li>Contribute to a network of creative people, anchored around the investigators and implementors who are closest to the problems in the countries most burdened by global health and development inequity and have the knowledge and perspective to direct the right approaches to the right parts of the problems to help ensure success – their collective action and directed energy is helping solve today's key problems in global health and development, while building a mechanism ready to solve tomorrow's</li>
	<li>Specifically address the meeting's goals and content around the response to the COVID-19 pandemic and beyond, noting that this funding opportunity is not designed to more broadly address COVID-19</li>
	<li>Are likely to yield a tangible answer to a question or solution to a problem within the grant term under the current and likely near-term constraints associated with the COVID-19 pandemic</li>
	<li>Are explicitly aligned with the content within the meeting's scientific tracks, noting that proposals will be reviewed based on their alignment with one primary track. Eligible scientific tracks for this Call-to-Action are listed below, and they include one separate scientific session (Novel Technologies for Global Health) as well as the entire Keystone Symposia Global Health Series conference overlapping with the Grand Challenges Annual Meeting. The Smart Farming Innovations track is not eligible, because it has its own separate <a href="https://gcgh.grandchallenges.org/grant-opportunities" target="_blank">request for proposals</a>.</li>
</ul>

Scientific tracks eligible for the Call-to-Action

<ul>
	<li>Addressing Challenges to Manage COVID-19: The Indian Experience - Addressing the need, the status, and the gaps that are unique to each solution and discussing the way forward for making all of these solutions accessible and affordable from an Indian perspective</li>
	<li>Applying a Translational Lens to Global Health - Exploring the use of translational tools in nutrition and COVID-19, including the challenges and opportunities from planning and executing clinical trials in a pandemic</li>
	<li>Global Partnerships &amp; Grand Challenges – Supporting local innovators solving local problems, helping build a critical mass of innovation champions linked through a global network to collectively address the most pressing global health and development challenges</li>
	<li>Leveraging Pathogen Genetic Sequencing - Sequencing SARS-CoV-2 during the COVID-19 pandemic, sequencing applied to epidemic and endemic pathogens, and building a suite of interoperable and open-source data analytics and visualization software packages for use in real-time epidemic and endemic disease control</li>
	<li>Optimizing Birth, Growth, and Development – Addressing the COVID-19 pandemic's direct and indirect effect on global health work around maternal, newborn, and child health, including pivoting resources during COVID-19, respiratory support in low- and middle-income countries, and studies of maternal (intrauterine) nutrition and fetal growth</li>
	<li>Repurposing Drugs for COVID-19: Approaches and Challenges – Exploring ongoing efforts to identify candidate drugs to repurpose for COVID-19 treatment and prophylaxis, including screening platforms and model systems</li>
	<li>Novel Technologies for Global Health – Showcasing development of the COVID-19 Cell Atlas and exploring the COVID-19 Human Tissue Atlas and a systems biology approach together with additional technologies</li>
	<li>Enabling Crop Analytics at Scale - Removing bottlenecks to large-scale collection, use, and sharing of ground truth data or processes for smallholder farmer applications</li>
	<li>Optimizing Nutrition for Maternal, Newborn, and Child Health (Keystone Symposia) – Emphasizing interdisciplinary research and connecting global nutrition and molecular nutrition experts</li>
</ul>

We will not consider funding approaches that:

<ul>
	<li>Are not explicitly aligned with the content within the meeting's scientific tracks eligible for this request for proposals that are listed above</li>
	<li>Are not accomplishable within the grant term under the current and likely near-term constraints associated with the COVID-19 pandemic</li>
</ul>

<h2>THE OPPORTUNITY</h2>

Embracing the tradition of microbial fermentation to transform locally available foods into naturally vitamin-fortified, toxin-free, flavorful, and shelf-stable products could empower local communities to mitigate the impact of COVID-19 on supply chain/food security and improve the health and nutrition of mothers and children in the most vulnerable settings. Historical advances in food processing have largely employed strategies that involve supplementation with micronutrients and additives to improve nutritional content and stability, but these approaches require highly centralized supply chains.<a href="#_edn1" name="_ednref1" title="">1</a> In addition, chemical additives for preservation, flavor and texture purposes may have unintended consequences of contributing to compromised gut health and increased prevalence of metabolic disease (hypertension, diabetes, obesity).<a href="#_edn2" name="_ednref2" title="">2</a>

Fermentation is an ancient practice through which locally-sourced food substrates can be transformed naturally by environmentally occurring microbes. These processes are thought to be intricately intertwined with human biology, and it is hypothesized that our primate ancestors adapted to natural fermentation processes millions of years ago.<a href="#_edn3" name="_ednref3" title="">3</a> While many fermented foods (e.g., yogurt, cheese, coffee and alcohol) remain popular, certain types of fermentation are a dwindling art in many settings, representing a loss of cultural heritage and a natural way to improve the qualities of foods across several distinct axes<a href="#_edn4" name="_ednref4" title="">4</a>:

<ul>
	<li>Improve macro- and micro-nutrient quality and bioavailability (e.g., B vitamins)<a href="#_edn5" name="_ednref5" title="">5</a></li>
	<li>Remove anti-nutrients (mycotoxins; phytates, which decrease iron availability)<a href="#_edn6" name="_ednref6" title="">6</a></li>
	<li>Transform taste, flavor and texture<a href="#_edn7" name="_ednref7" title="">7</a></li>
	<li>Improve the preservation and stability of foods by excluding pathogens (through lowering pH, bacteriocin production, removing simple sugars)<a href="#_edn8" name="_ednref8" title="">8</a></li>
</ul>

Historical approaches of macronutrient supplementation and micronutrient fortification have been the basis for transformative global health nutrition interventions, ultimately saving millions of lives each year.<a href="#_edn9" name="_ednref9" title="">9</a> These approaches have also focused on pediatric populations, although recent work suggests that solutions targeting maternal nutrition may be even more impactful on pediatric health and have the important benefit of also improving maternal health.<a href="#_edn10" name="_ednref10" title="">10</a> Given limited access of nutritional interventions by the populations in greatest need<a href="#_edn11" name="_ednref11" title="">11</a> and formulations that are not optimized for gut and metabolic health,<a href="#_edn12" name="_ednref12" title="">12</a> malnutrition remains one of the most significant global health problems facing society today.

COVID-19, with disruption of supply chains and a predilection for individuals with metabolic diseases, has served to increase the urgency for identifying locally-sourceable health-promoting maternal nutrition solutions that treat undernutrition without increasing the risk of obesity, diabetes, and hypertension. Ironically, it may be that these new solutions already exist in the form of ancient traditions reevaluated and revalued through a next-generation and evidence-based lens.

<h2>THE CHALLENGE</h2>

Beyond many of the well-known examples of microbial fermentation, the vast majority of fermentation processes around the world remain uncharacterized and their potential human health benefits are unknown. These ancient practices may hold the key to impactful and locally targeted nutritional interventions that combine tradition and science to tackle malnutrition. Rigorous scientific evaluation has been limited and characterization to understand potential benefits could be pursued to validate and underscore the importance of preserving this cultural heritage.

What we are looking for

This call seeks to fund pilot studies that investigate the biological effect of traditional locally fermented foods on key microbiome, gut, and health biomarkers in local populations. The goal is to provide investigators in Sub-Saharan Africa and South Asia with the resources to build local capacity to investigate fermented foods as novel maternal nutrition interventions. In particular, sequencing technology – a transformative tool that has enabled in-depth investigation of microbial communities – will be provided to all investigators to democratize the ability to investigate foods and health effects, and build local capacity. Ultimately, the goal is to empower local communities to develop geography and culture specific interventions powered by fermentation, in country.

Proposals should specifically address the following core elements, but investigators are welcome to propose creative strategies and designs to accomplish the core goals of this call and account for local cultural traditions. In addition, it is expected that study design will be refined after award through a collaborative forum invovling other awardees and the foundation:

<ul>
	<li>Identification of a local (geographic/cultural) fermented food for study
	<ul>
		<li>Many foods may not be colloquially considered to be fermented, but any process that incorporates biotransformation by microbes is acceptable</li>
		<li>Living microbes were actively employed as a part of the fermentation process and final product consumed retains live organisms</li>
		<li>Fermentation may be driven by known organisms, e.g. bacterial Lactobacillus sp., fungal Aspergillus sp., or less studied food-borne organisms</li>
		<li>Must be plant-based (e.g., grain or staple crop). Plant-based fermented foods are a requirement due to lower cost of goods for scalability compared to animal-based foods</li>
		<li>Food with a cultural precedent in maternal nutrition are of high interest</li>
		<li>The food being investigated must be produced in compliance under all relevant local food manufacturing regulations and modern food safety practices</li>
	</ul>
	</li>
	<li>Pilot study design for longitudinal intervention study for understanding the effect of the fermented food in a naïve (no, or limited, fermented food consumption) population
	<ul>
		<li>The target population should be women of reproductive age, and a naive population not currently consuming or with limited consumption of the target fermented food to better understanding the biological effects of the food itself. Different subpopulations (urban vs. rural, various cultural groups, different sub-geographies within a country, etc.) with lower consumption of the target fermented food could be specifically targeted. If populations traditionally consuming fermented foods are considered, it would be important to undertake a baseline to understand the additive effect after consumption of "target foods".</li>
		<li>Longitudinal intervention studies are recommended, with small cohort sizes (20-30 participants) and sustained exposure to the fermented food (e.g., at least daily &gt;5 days) but ultimately the study design should be motivated by the end goal of characterizing the effects of the food on maternal nutrition through host (blood and fecal) and gut microbiome biomarkers.</li>
		<li>A template dietary questionnaire will be provided and can be customized to local foods and traditions</li>
		<li>Existing infrastructure that may improve ability to execute on the proposed study can and should be highlighted</li>
	</ul>
	</li>
	<li>Biological sample biobanking and characterization before and after food intervention
	<ul>
		<li>Fermented foods themselves (metagenomic analysis of fungal [ITS] and bacterial [16S] constituents), potentially across distinct batches and preparation methods</li>
		<li>Serial fecal samples from participants (metagenomic analysis; lipocalin-2, myeloperoxidase, and calprotectin of particular interest)</li>
		<li>Serial serum/blood samples from participants (Iron studies, B-vitamin analysis; lipocalin-2, IL-6 and CRP are of particular interest given the association of inflammation biomarkers with maternal nutrition and birth outcomes) <a href="#_edn13" name="_ednref13" title="">13</a></li>
		<li>Other characterization approaches of food (including effects of fermentation on the nutritional profile) or biological samples using conventional or existing techniques</li>
		<li>Proposals should specifically address existing laboratory infrastructure and capacity for integrating next generation sequencing into existing laboratory workflows (e.g. nucleic acid extraction, PCR, etc.)</li>
	</ul>
	</li>
</ul>

As a part of this 18 month Grand Challenges award, sequencing platforms (funded with up to USD $40K for sequencing technology out of this USD $200K award) and training will be provided to investigators to enable local sequence-based characterization of the fermented foods and microbiome effects. The output of this study will be pilot data evaluating the biological effect of traditional fermented foods on gut, microbiome and health axes in local populations. Any additional points on the sustainability of the intervention and the empowerment of local champions to continue the work, integrating with state and national level Maternal, Infant and Young Child Nutrition (MIYCN) programs would also be welcome.

What we will not consider funding 

<ul>
	<li>Investigators and institutions not located in Sub-Saharan Africa or South Asia</li>
	<li>Investigators not studying local foods (specific to the culture or geography)</li>
	<li>Investigators not investigating local populations</li>
	<li>Proposals that do not contain a human interventional study targeted towards women of reproductive age. No studies on child populations will be funded.</li>
	<li>Proposals not addressing all the stated study design criteria above</li>
	<li>Proposals that do not demonstrate a capacity to perform the research proposed; investigators should describe capacity for human studies, sample collection, processing and storage, including but not limited to:
	<ul>
		<li>Relevant approvals from local authorities/institutions/Government on the research methodology and sharing of data among collaborators, eventually for global access</li>
		<li>Data analysis and adherence to relevant local laws/ policies pertaining to data sharing, hosting and data protection.</li>
		<li>Secure handling of personally identifiable information data and research results</li>
		<li>Institutional Review Boards or equivalent human study regulation strategy</li>
		<li>Sample collection capacity/protocols and capacity for sample storage</li>
		<li>Ability to perform human biological sample characterization as proposed</li>
	</ul>
	</li>
</ul>

</ul>Historical approaches of macronutrient supplementation and micronutrient fortification have been the basis for transformative global health nutrition interventions, ultimately saving millions of lives each year.<a href="#_edn9" name="_ednref9" title="" id="_ednref9">9</a> These approaches have also focused on pediatric populations, although recent work suggests that solutions targeting maternal nutrition may be even more impactful on pediatric health and have the important benefit of also improving maternal health.<a href="#_edn10" name="_ednref10" title="" id="_ednref10">10</a> Given limited access of nutritional interventions by the populations in greatest need<a href="#_edn11" name="_ednref11" title="" id="_ednref11">11</a> and formulations that are not optimized for gut and metabolic health,<a href="#_edn12" name="_ednref12" title="" id="_ednref12">12</a> malnutrition remains one of the most significant global health problems facing society today.
COVID-19, with disruption of supply chains and a predilection for individuals with metabolic diseases, has served to increase the urgency for identifying locally-sourceable health-promoting maternal nutrition solutions that treat undernutrition without increasing the risk of obesity, diabetes, and hypertension. Ironically, it may be that these new solutions already exist in the form of ancient traditions reevaluated and revalued through a next-generation and evidence-based lens.
<h2>THE CHALLENGE</h2>
Beyond many of the well-known examples of microbial fermentation, the vast majority of fermentation processes around the world remain uncharacterized and their potential human health benefits are unknown. These ancient practices may hold the key to impactful and locally targeted nutritional interventions that combine tradition and science to tackle malnutrition. Rigorous scientific evaluation has been limited and characterization to understand potential benefits could be pursued to validate and underscore the importance of preserving this cultural heritage.
What we are looking for
This call seeks to fund pilot studies that investigate the biological effect of traditional locally fermented foods on key microbiome, gut, and health biomarkers in local populations. The goal is to provide investigators in Sub-Saharan Africa and South Asia with the resources to build local capacity to investigate fermented foods as novel maternal nutrition interventions. In particular, sequencing technology – a transformative tool that has enabled in-depth investigation of microbial communities – will be provided to all investigators to democratize the ability to investigate foods and health effects, and build local capacity. Ultimately, the goal is to empower local communities to develop geography and culture specific interventions powered by fermentation, in country.
Proposals should specifically address the following core elements, but investigators are welcome to propose creative strategies and designs to accomplish the core goals of this call and account for local cultural traditions. In addition, it is expected that study design will be refined after award through a collaborative forum invovling other awardees and the foundation:
<ul><li>Identification of a local (geographic/cultural) fermented food for study
<ul><li>Many foods may not be colloquially considered to be fermented, but any process that incorporates biotransformation by microbes is acceptable</li>
<li>Living microbes were actively employed as a part of the fermentation process and final product consumed retains live organisms</li>
<li>Fermentation may be driven by known organisms, e.g. bacterial Lactobacillus sp., fungal Aspergillus sp., or less studied food-borne organisms</li>
<li>Must be plant-based (e.g., grain or staple crop). Plant-based fermented foods are a requirement due to lower cost of goods for scalability compared to animal-based foods</li>
<li>Food with a cultural precedent in maternal nutrition are of high interest</li>
<li>The food being investigated must be produced in compliance under all relevant local food manufacturing regulations and modern food safety practices</li>
</ul></li>
<li>Pilot study design for longitudinal intervention study for understanding the effect of the fermented food in a naïve (no, or limited, fermented food consumption) population
<ul><li>The target population should be women of reproductive age, and a naive population not currently consuming or with limited consumption of the target fermented food to better understanding the biological effects of the food itself. Different subpopulations (urban vs. rural, various cultural groups, different sub-geographies within a country, etc.) with lower consumption of the target fermented food could be specifically targeted. If populations traditionally consuming fermented foods are considered, it would be important to undertake a baseline to understand the additive effect after consumption of "target foods".</li>
<li>Longitudinal intervention studies are recommended, with small cohort sizes (20-30 participants) and sustained exposure to the fermented food (e.g., at least daily &gt;5 days) but ultimately the study design should be motivated by the end goal of characterizing the effects of the food on maternal nutrition through host (blood and fecal) and gut microbiome biomarkers.</li>
<li>A template dietary questionnaire will be provided and can be customized to local foods and traditions</li>
<li>Existing infrastructure that may improve ability to execute on the proposed study can and should be highlighted</li>
</ul></li>
<li>Biological sample biobanking and characterization before and after food intervention
<ul><li>Fermented foods themselves (metagenomic analysis of fungal [ITS] and bacterial [16S] constituents), potentially across distinct batches and preparation methods</li>
<li>Serial fecal samples from participants (metagenomic analysis; lipocalin-2, myeloperoxidase, and calprotectin of particular interest)</li>
<li>Serial serum/blood samples from participants (Iron studies, B-vitamin analysis; lipocalin-2, IL-6 and CRP are of particular interest given the association of inflammation biomarkers with maternal nutrition and birth outcomes) <a href="#_edn13" name="_ednref13" title="" id="_ednref13">13</a></li>
<li>Other characterization approaches of food (including effects of fermentation on the nutritional profile) or biological samples using conventional or existing techniques</li>
<li>Proposals should specifically address existing laboratory infrastructure and capacity for integrating next generation sequencing into existing laboratory workflows (e.g. nucleic acid extraction, PCR, etc.)</li>
</ul></li>
</ul>As a part of this 18 month Grand Challenges award, sequencing platforms (funded with up to USD $40K for sequencing technology out of this USD $200K award) and training will be provided to investigators to enable local sequence-based characterization of the fermented foods and microbiome effects. The output of this study will be pilot data evaluating the biological effect of traditional fermented foods on gut, microbiome and health axes in local populations. Any additional points on the sustainability of the intervention and the empowerment of local champions to continue the work, integrating with state and national level Maternal, Infant and Young Child Nutrition (MIYCN) programs would also be welcome.
What we will not consider funding 
<ul><li>Investigators and institutions not located in Sub-Saharan Africa or South Asia</li>
<li>Investigators not studying local foods (specific to the culture or geography)</li>
<li>Investigators not investigating local populations</li>
<li>Proposals that do not contain a human interventional study targeted towards women of reproductive age. No studies on child populations will be funded.</li>
<li>Proposals not addressing all the stated study design criteria above</li>
<li>Proposals that do not demonstrate a capacity to perform the research proposed; investigators should describe capacity for human studies, sample collection, processing and storage, including but not limited to:
<ul><li>Relevant approvals from local authorities/institutions/Government on the research methodology and sharing of data among collaborators, eventually for global access</li>
<li>Data analysis and adherence to relevant local laws/ policies pertaining to data sharing, hosting and data protection.</li>
<li>Secure handling of personally identifiable information data and research results</li>
<li>Institutional Review Boards or equivalent human study regulation strategy</li>
<li>Sample collection capacity/protocols and capacity for sample storage</li>
<li>Ability to perform human biological sample characterization as proposed</li>
</ul></li>

<h2>THE OPPORTUNITY</h2>

At the Bill &amp; Melinda Gates Foundation, we believe that malaria eradication within a generation is possible. We recognize that in order to achieve this, National Malaria Control Programs (NMCPs) must be empowered to use timely, high-quality data to inform their malaria strategic planning, decision-making, program implementation, and evaluation. As we work to sustain the decline in incidence rates that have marked the last fifteen years of malaria control, this concept of data-to-action has never been more important.

Our vision for data-to-action, recently endorsed by WHO’s Malaria Policy Advisory Committee (MPAC), is one of stratification and sub-national tailoring. In the first step, multiple data sources – from geospatial to epidemiological data – are used to define district-level strata within a country. Next, additional data types are used as the input to mathematical models that output the optimal package of interventions that result in maximum malaria burden reduction within a given resource envelope. The success of stratification and sub-national tailoring is highly dependent on the underlying data, which may not always be complete, high-quality, and / or timely. We are therefore exploring new data streams that might improve our understanding of factors driving changes in malaria epidemiology or be used to optimize the choice of interventions modelled. One of these new data streams is serological, genetic, and / or genomic data which arises from malaria molecular surveillance.

Malaria Molecular Surveillance (MMS) is an umbrella term which describes the use of molecular biology approaches – from serology to genotyping to whole genome sequencing (WGS) – to interrogate parasite and / or vector populations in order to derive epidemiologically actionable information. MMS does not include research-oriented genetic and genomic investigations, such as studies using genomics to investigate parasite or mosquito biology. Rather, the emphasis is on analyses that can directly influence malaria control policy and practice. In addition to the laboratory techniques used, MMS also includes the bioinformatics tools and resources necessary to process, interpret, and share the resulting data.

<h2>THE CHALLENGE</h2>

Initial work in the MMS space focused on methods development and proof-of-concept pilot studies. Now, the tools and analyses are maturing, the infrastructure is in place, and the time-to-result is much shorter, meaning that MMS is beginning to influence program planning and execution. In elimination settings, genetics has been deployed in focused investigations of malaria importations. In higher-burden settings, MMS is being used to visualize the spatio-temporal spread of antimalarial drug resistance markers, influencing treatment guidelines, and to track the effect of different interventions on parasite genetic diversity as a surrogate measure of transmission intensity.

In June 2019, a WHO Technical Consultation on the role of parasite and vector genetic and genomic data in malaria surveillance (<a href="https://www.who.int/malaria/mpac/mpac-october2019-session7-report-consultation-on-genomics.pdf" target="_blank">workshop report</a>), stakeholders from MMS community – both on the research and programmatic sides – gathered with the goal of identifying those MMS use cases for which sufficient evidence exists to recommend routine use for malaria control and elimination, and those for which more upstream research is needed in order to generate a broader evidence base for future recommendations.

The list of use cases that are ready or near ready (marked with an asterisk*) for programmatic deployment includes:

<ul>
	<li>Detect drug resistance: monitor the prevalence/frequency of molecular markers of drug resistance to inform intervention selection, treatment guidelines, and surveillance</li>
	<li>Detect hrp2/3 deletions: monitor the prevalence/frequency of hrp2/3 deletion affecting RDT efficacy to inform diagnostic selection</li>
	<li>Assess drug resistance gene flow: determine the origins of drug resistance markers and monitor their spread within/among regions and parasite populations to inform containment strategies and regional policies around intervention selection, treatment guidelines, and surveillance*</li>
	<li>Predict emerging resistance: detect signatures of positive selection suggesting emerging resistance to inform intervention selection, treatment guidelines, and surveillance*</li>
	<li>Identify local transmission: identify focal areas of high transmission and clusters of infections to inform resource deployment*</li>
	<li>Distinguish local and imported cases: in elimination settings, classify cases as imported or otherwise for case investigation and elimination certification*</li>
	<li>Reconstruct transmission chains: elucidate contributing factors (e.g. seasonality, migrants, asymptomatic cases, and highly infectious individuals) to ongoing transmission patterns to inform intervention selection, resource deployment, surveillance, and case investigation*</li>
	<li>Determine connectivity of parasite populations: assess degree to which transmission is linked among regions due to linked parasite populations to inform program planning and resource deployment*</li>
	<li>Survey for allelic variation in target sites for gene drive: determine whether SNPs that would prevent CRISPR site recognition exist in wild populations to optimize gene drive release planning*</li>
</ul>

As MMS transitions from proof-of-concept work in academic institutions to operational reality in NMCPs, Ministries of Health, and National Public Health Institutes, the challenge lies in conducting the work in a way that engages country programs and malaria decision-makers and that empowers them to understand and use their data actively for programmatic decision-making.

The purpose of this call is therefore to identify new and innovative approaches to integrating malaria molecular surveillance into malaria surveillance and programmatic decision-making in malaria endemic countries. 

What we are looking for:

We are looking for innovative proposals that will use MMS data to enable NMCPs to inform their national and sub-national surveillance efforts, national strategic planning, and/or intervention implementation. These may include proposals that: create or expand laboratory, bioinformatics, and data interpretation capacity within NMCPs or at institutions closely affiliated with an NMCP; create or implement tools for communicating and sharing parasite and/or vector molecular surveillance data; and/or build relationships between groups with MMS capacity and NMCP partners. Proposals should target the use cases identified above that are ready or near-to-ready for programmatic deployment. We do not want respondents to be generating MMS data for research purposes; rather, the intent of this call is to support the application of MMS approaches to routine malaria surveillance and planning within NMCPs, Ministries of Health, or similar organizations.

While we welcome respondents from around the world, we are particularly interested in proposals from respondents working in high-burden malaria settings. All proposals must include a principal investigator or co-investigator from a malaria-endemic country.

Winning proposals should:

<ul>
	<li>Explain the rationale for and potential benefits of using MMS data in their setting</li>
	<li>Address one or more of the use cases outlined in the Challenge section above</li>
	<li>Include representation from the NMCP, Ministry of Health (MOH) representation, government agency or healthcare provider responsible for malaria control in the country / region</li>
	<li>Describe how MMS information arising from the project will be shared with the NMCP, MOH and other key stakeholders</li>
</ul>

A few examples of work that would be considered for funding:

<ul>
	<li>Implementing or scaling-up a laboratory assay for hrp2/3 deletion and / or antimalarial drug resistance marker surveillance in partnership with an NMCP</li>
	<li>Developing a web interface or reporting tool for communicating molecular data to stakeholders who do not have genomics / bioinformatics experience</li>
	<li>Creating a bioinformatics workflow for MMS data that goes from fastq file to a readable report summarizing the analysis results in a user-friendly way</li>
	<li>Developing and implementing a training program to familiarize NMCP staff with the use and interpretation of MMS data</li>
</ul>

We will not consider funding for:

<ul>
	<li>Proposals that do not include an investigator from a malaria-endemic country</li>
	<li>Proposals that do not include an explicit partnership with the NMCP, MOH or other authority responsible for malaria surveillance and control in the country / region</li>
	<li>Proposals that do not demonstrate how the results will immediately influence malaria decision-making by the relevant NMCP, MOH or other authority</li>
</ul>

<h2>Summary</h2>

Smart Farming Innovations for Small-Scale Producers Request for Proposals (RFP) seeks Smart Farming solutions that leverage digital technology innovations that have the potential to drive positive impact for smallscale producer (SSP) entrepreneurs delivered through bundled farmer services and enabled by scalable digital and data platforms (<a href="#Fig1" id="_Fig1">Figure 1</a>). Solutions should address one or more challenges faced by smallscale crop and livestock producers in one or more areas of agricultural advisory, farm management decision support, input supply, finance, insurance, market access and linkages. Solutions should use human-centered design to elucidate the barriers that prevent SSPs from improving productivity, profitability and income – then propose Smart Farming solutions that can help elevate smallscale production entrepreneurs. Some of the fundamental challenges to address include: 1) low productivity driven by lack of access to information and services; climate change, weather variability and pest and disease outbreaks; 2) lack of access to tailored financial and insurance products, and 3) lack of access to and choice of market and offtake options. Additionally, solutions will need to consider barriers to adoption of digital farmer services, such as low language and digital literacy, the high relative cost of services and devices and, in particular, gender gaps and other potential downsides of digital solutions (e.g. the growing digital divide).

Smart Farming Innovations for Small-Scale Producers

Note: Please see the request for proposals document with additional background as a PDF file on the right.
<h2>Summary</h2>
Smart Farming Innovations for Small-Scale Producers Request for Proposals (RFP) seeks Smart Farming solutions that leverage digital technology innovations that have the potential to drive positive impact for smallscale producer (SSP) entrepreneurs delivered through bundled farmer services and enabled by scalable digital and data platforms (<a href="#Fig1" id="_Fig1">Figure 1</a>). Solutions should address one or more challenges faced by smallscale crop and livestock producers in one or more areas of agricultural advisory, farm management decision support, input supply, finance, insurance, market access and linkages. Solutions should use human-centered design to elucidate the barriers that prevent SSPs from improving productivity, profitability and income – then propose Smart Farming solutions that can help elevate smallscale production entrepreneurs. Some of the fundamental challenges to address include: 1) low productivity driven by lack of access to information and services; climate change, weather variability and pest and disease outbreaks; 2) lack of access to tailored financial and insurance products, and 3) lack of access to and choice of market and offtake options. Additionally, solutions will need to consider barriers to adoption of digital farmer services, such as low language and digital literacy, the high relative cost of services and devices and, in particular, gender gaps and other potential downsides of digital solutions (e.g. the growing digital divide).

Grand Challenges Explorations – Brazil: Data Science Approaches to Improve Maternal and Child Health, Women's Health and Children's Health in Brazil

<h2>THE OPPORTUNITY</h2>

Fundamental changes in menstrual health and hygiene (MHH) products are needed to meet the needs of women and girls in low and middle income countries (LMIC) who face challenges with regard to their overall menstrual health and to managing their menstrual periods with dignity. Women and girls in LMIC face significant challenges barriers related to MHH from menarche to menopause. Current literature, while limited, shows an association between inadequate access to MHH products and poorer physical and mental health outcomes.<a href="#_ftn1" name="_ftnref1" title="">[1]</a> <a href="#_ftn2" name="_ftnref2" title="">[2]</a> In Ethiopia, for example, only 28% of women and girls reported having "everything they need" to manage their menstruation. Globally, based on data collected from 8 countries in PMA2020 (Performance Monitoring for Action, 2020), it is estimated that 528 million women and girls are lacking what they need for basic MHH care. Challenges can range from social stigma, lack of clean water for basic hygiene, and ineffective, inadequate, or expensive products.<a href="#_ftn3" name="_ftnref3" title="">[3]</a> For example, many women and girls face limited economic resources to purchase supplies that best meet their needs. In addition, girls face inadequate or poor water and sanitation facilities at school, lack of privacy and lengthy travel to and from schools, which increases the likelihood of leaks/stains. Lack of access to MHH products that are context-appropriate, affordable and sustainable can have tangible biological and social impact. Additionally, limited access to MHH products leads to diminished dignity and respect and increased discrimination and stigma for many women and girls in LMIC across their reproductive life.

Key characteristics of MHH products for women and girls include effectiveness, safety, discretion, sustainability, and affordability. Currently available products (e.g., disposable pads, reusable pads, tampons, and menstrual cups) all involve trade-offs among one or more of these desired characteristics and attributes. For example, menstrual cups are discreet but expensive and difficult to use; disposable pads are discreet but create a lot of waste that is particularly problematic in LMICs. Additionally, lack of access to clean water limits the utility of reusable products (e.g., menstrual cups) for many women. As a result, some women and girls turn to inadequate and potentially harmful homemade alternatives such as goatskin, cow patties, or cloths in many settings. In India for example, 88% of women and girls use homemade alternative products to manage MHH.

While a multi-pronged approach to address dignified menstrual health is broadly necessary, one key need is innovation in materials science and transformative product development to better meet user needs. This Grand Challenge opportunity is focused exclusively on the product innovation domain. To date, changes in this field have been largely incremental - often focusing on increasing access through pricing or making current products with biodegradable materials. Disruptive innovation in this space has the potential to shift the current market structure and thus improve reach to poor and vulnerable populations. To be most impactful, significant changes in science and technology require mitigation of environmental impact with the aspirational goal to create zero waste and move toward a circular economy (defined as an economic system aimed at eliminating waste and the reuse, sharing, repair, refurbishment, remanufacturing, and recycling of resources).

<h2>THE CHALLENGE</h2>

We seek fundamentally transformative and innovative ideas to support the design and development of new MHH products that meet key criteria of being responsive to user needs - particularly in LMIC context; with priority focus on safety, unobtrusiveness, effectiveness (no leaking), cultural acceptability, and sustainability. While there are a number of challenges related to access to current products, reducing stigma, and shifting social norms, this opportunity is specifically focused on driving transformative innovation in the product development domain. We are particularly seeking new technologies, including those potentially used in adjacent fields such as materials science, that could be adapted to innovative MHH products. We fully recognize that technology alone does not automatically improve people's lives. Thus, these creative solutions must be contextually grounded and designed in response to the needs and preferences of women and girls living in LMIC and designed particularly with the future in mind.

Proposals should include how they will address the following criteria:

<ul>
	<li>Innovation: We are seeking radical transformation of existing MHH products, including leveraging materials science and other product innovations.</li>
	<li>Discretion: The ability to use a product without it being detected is of high importance to women and girls, specifically during: wear (e.g., no blood leaking and staining clothes), cleaning (e.g., for reusable products, washing product can be kept discreet and is feasible in the absence of clean water supply), and disposal (e.g., for disposable products, does not leave conspicuous waste). Other considerations include safety (e.g., obviating the need to access public sanitation facilities at night). Finally, functionality over the life course depends upon adaptability to times of irregular and sometimes heavy bleeding, including perimenarche, postpartum, and perimenopause.</li>
	<li>Sustainability: Current MHH products either require access to clean water to clean (e.g., menstrual cup) or result in waste (e.g., disposable pad). A transformative product would neither require neither clean water nor result in waste.</li>
</ul>

Note: Given the foundation's target geographies and populations, a MHH product needs to be affordable for a woman throughout her reproductive years. This criterion will need to be weighed carefully against the prior criteria. While striving for a low cost of goods sold (COGS), we also recognize that affordability can be addressed through multiple levers including market dynamics and scaled production.

The following will not be considered for funding:

<ul>
	<li>Basic research in materials science or product design that does not address the criteria as outlined above</li>
	<li>Proposals only focusing on innovative new materials science without a clear path toward developing an MHH prototype manufacturing process</li>
	<li>Proposals where there is no clear path forward to scale</li>
	<li>Proposals focused on current MHH product delivery and education, as opposed to a technological solution for innovations in new products</li>
	<li>Proposals that focus on incremental change of existing products</li>
	<li>Proposals focused on other aspects of MHH, including infrastructure/systems for addressing access to existing products, water and sanitation improvements or shifting social norms around stigmatization.</li>
</ul>

<h2>BACKGROUND</h2>

Cesarean section (CS) is a life-saving procedure for mother and newborn. However, too often c-section is not available, is provided without adequate quality, or is provided when not medically indicated - all dimensions that lead to maternal and newborn mortality and morbidity. We see an opportunity to nurture the field to identify and demonstrate feasibility of interventions to address challenges related to safe, timely, and appropriate cesarean section in low and middle income countries.

<h2>THE CHALLENGE</h2>

We invite proposals for interventions to address the following challenges related to the cesarean section:

<ol>
	<li>Increasing access to cesarean section where it is currently inadequate</li>
	<li>Increasing quality and safety of cesarean section to reduce iatrogenic harm to both mothers and newborns</li>
	<li>Reducing rates of non-medically indicated cesarean section.</li>
</ol>

Interventions addressing more than one challenge (e.g. quality and access) are encouraged. In some geographies all three of these challenges exist simultaneously, at different times for different populations; in other geographies only one or two of these challenges predominate. Applications should clearly state which of these three challenges is being targeted and provide clear rationale for why the intervention is likely to address the challenge. We are particularly interested in geographies with high fertility and weak health systems that will face challenges to ensure the provision of safe c-sections can keep pace with medical need, and we will thus consider applications proposing activities to be implemented in Sub-Saharan Africa or South Asia (India, Pakistan, Bangladesh).

Grant Funding Levels

We seek to make Seed Grants to generate proof of concept of novel interventions together with Validation Grants to generate further evidence of feasibility at a larger scale for existing interventions.

<ul>
	<li>Seed Grants of $100K for up to 24 months: These grants are intended to provide proof of concept of an intervention that is entirely novel at small scale (e.g., single facility or district). Applicants should conduct a literature review to verify that the proposed intervention has no documented evidence; documentation of the methods and outcomes of this review must be provided in the application. These grants should demonstrate the feasibility of a novel intervention and its impact on one or more of the c-section challenges identified in this call for applications.</li>
	<li>Validation Grants of $300K for up to 24 months: These grants are intended to demonstrate the feasibility of a single intervention or a combination of interventions at the scalable unit <a href="#_ftn1" id="_ftnref1">[1]</a> of a health system. Validation grants must replicate, confirm or more rigorously test one intervention - or multiple interventions - that have previously demonstrated proof of concept at a smaller scale. Given the complexity of the problem, we acknowledge that multi-component interventions are required, and we eoncourage applications exploring these.</li>
</ul>

What We Are Looking For:

All applications should:

<ul>
	<li>Focus on health service or delivery innovation. This call for applications excludes development of new medical devices and non-interventional analysis of data</li>
	<li>Describe how the intervention will be tailored to the epidemiology and health system where it will be implemented</li>
	<li>Ensure that women and newborns receive care that respects and preserves their dignity, including informed consent<a href="#_ftn2" id="_ftnref2" name="_ftnref2">[2]</a></li>
	<li>Include participation from institutions based in South Asia and sub-Saharan Africa; applications led by institutions from these geographies are encouraged</li>
	<li>Propose interventions that align with the attributes of scalable health innovations<a href="#_ftn3" id="_ftnref3" name="_ftnref3">[3]</a></li>
	<li>Report impact on c-section rates disaggregated by Robson classification<a href="#_ftn4" id="_ftnref4" name="_ftnref4">[4]</a>, and safety with indicators such as case fatality rates and rates of post-operative complication</li>
	<li>Propose activities to be implemented in a country in Sub-Saharan Africa or South Asia (India, Pakistan, Bangladesh).</li>
</ul>

A few of the many options we will consider include (but are not limited to): clinical team huddles for improving quality of CS; interventions to improve immediate breastfeeding and bonding among mother-infant pairs after CS; interventions to improve communication between patient and care team; restructuring labor wards to facilitate latent phase labor management; adjustments to financial incentives related to CS; policy and liability reform.

We will not consider funding for approaches that have been widely used and evaluated in LMIC settings to scale up access to cesarean section (e.g., task shifting); activities to improve quality of care that already have extensive evidence of effectiveness; emergency transport interventions; mass media campaigns; or development of new tools for surgery, anesthesia, or patient monitoring.

Collaboration

This request for proposals seeks to create a consortium of individually funded projects that will benefit from sharing information between projects. We expect that such sharing will help to ensure that the goals of the innovative approaches in individual projects are ultimately integrated with each other, thereby increasing the chances that the programs will be greater than the sum of their parts. Furthermore, we expect that sharing experimental methods, data, and resources will ultimately improve the ability to compare and validate local research findings and to develop interventions and products. We expect to bring together all grantees after 18-24 months to share what they have learned in their work and to discuss how to accelerate progress with these lessons.

Improving Access to and Use of Safe and Appropriate Cesarean Section

<h2>BACKGROUND</h2>
Cesarean section (CS) is a life-saving procedure for mother and newborn. However, too often c-section is not available, is provided without adequate quality, or is provided when not medically indicated - all dimensions that lead to maternal and newborn mortality and morbidity. We see an opportunity to nurture the field to identify and demonstrate feasibility of interventions to address challenges related to safe, timely, and appropriate cesarean section in low and middle income countries.
<h2>THE CHALLENGE</h2>
We invite proposals for interventions to address the following challenges related to the cesarean section:
<ol><li>Increasing access to cesarean section where it is currently inadequate</li>
<li>Increasing quality and safety of cesarean section to reduce iatrogenic harm to both mothers and newborns</li>
<li>Reducing rates of non-medically indicated cesarean section.</li>
</ol>Interventions addressing more than one challenge (e.g. quality and access) are encouraged. In some geographies all three of these challenges exist simultaneously, at different times for different populations; in other geographies only one or two of these challenges predominate. Applications should clearly state which of these three challenges is being targeted and provide clear rationale for why the intervention is likely to address the challenge. We are particularly interested in geographies with high fertility and weak health systems that will face challenges to ensure the provision of safe c-sections can keep pace with medical need, and we will thus consider applications proposing activities to be implemented in Sub-Saharan Africa or South Asia (India, Pakistan, Bangladesh).

Grand Challenges seeks ideas for interventions to address the following challenges related to cesarean section: 1) increasing access to cesarean section where it is currently inadequate, 2) increasing quality and safety of cesarean section to reduce iatrogenic harm to both mothers and newborns, 3) reducing rates of non-medically indicated cesarean section. Proposed activities should be implemented in Sub-Saharan Africa or South Asia (India, Pakistan, Bangladesh).

<h2>THE OPPORTUNITY</h2>

Countries rely on both routine health systems and campaign-based delivery to extend the reach of important health products. Many programs, including immunization, neglected tropical diseases, nutrition, malaria, and polio regularly rely on such campaigns to support accelerated disease control, make progress towards elimination/eradication goals, and achieve large scale health impact.

Campaign-based delivery of health interventions is typically time-limited, intermittent, and implemented at-scale. All countries utilize health campaigns in some capacity - such as for outbreak response - and campaigns have been shown to be an effective way of driving health impact. For example, Vitamin A supplementation is estimated to reduce risk of all-cause child mortality by 12%. <a href="#_ftn1" id="_ftnref1" name="_ftnref1">[1]</a> Measles campaigns are estimated to reach 66% of "zero-dose" children who are not otherwise immunized by routine health systems. <a href="#_ftn2" id="_ftnref2" name="_ftnref2">[2]</a>

Still, the performance of campaigns is variable, and campaigns often do not realize their potential impact. For example, only 47% of the measles campaigns and 38% of vitamin A campaigns reached their intended coverage targets.<a href="#_ftn3" id="_ftnref3" name="_ftnref3">[3]</a>&nbsp;Campaign evaluations may also show they consistently miss a subset of populations - most often the most vulnerable - resulting in reduced equity of the health intervention. Although many campaigns experiment with or implement innovations to increase effectiveness, these innovations are rarely systematically evaluated, iterated upon, and disseminated.

Quality planning is a key enabler of effective campaign implementation and is critical to support campaign performance. More specifically, microplanning, which specifically addresses the detailed, delivery-level planning required to reach intended populations with a health intervention, is recognized as a critical driver of campaign success. Planning and microplanning can be used as a tool to identify and reach the most vulnerable populations (e.g., high-risk and unreached populations).

We believe there is opportunity to dramatically&nbsp;improve the way health campaigns that deliver health products or services realize impact, including through improved planning/microplanning. These campaigns will achieve higher coverage of target populations, better identify and reach high-risk/unreached populations, and efficiently use campaign resources.

<h2>THE CHALLENGE</h2>

We are seeking innovative solutions that accelerate the improvement of coverage, reach, efficiency, and effectiveness of mass health campaigns that deliver health products or services in low-and middle-income countries, specifically through improved planning/microplanning and focus on unreached populations.

Specifically, we are looking for innovations in approaches, practices, or tools that dramatically improve the&nbsp;planning/microplanning that will lead to improved effectiveness of campaigns. We are also looking for innovative tools and technologies to more effectively identify and reach the most vulnerable populations when countries are designing and implementing mass campaigns.

In order to contribute to the development and spread of campaign "best practices", a solution should be applicable to campaigns beyond the context in which it is originally tested (e.g., applicable in&nbsp;multiple&nbsp;lower- to middle-incomes countries and/or applicable&nbsp;across multiple types of health campaigns&nbsp;such as immunization, NTDs, malaria, or nutrition).

We are especially interested in novel approaches that draw on innovation from large-scale delivery models outside of the health sector, which may include interventions used in the private sector.

Successful proposals should consider the following:

Planning and microplanning: This includes the planning processes - led by governments and often supported by partners - at the national, sub-national, facility, or community levels. Overall planning supports the mobilization of information and resources needed to conduct the campaign, and&nbsp;<a href="https://www.who.int/polio-transition/documents-resources/best-practices-microplanning.pdf?ua=1" target="_blank">microplanning</a>&nbsp;specifically addresses the detailed, delivery-level planning required to reach intended populations with the health intervention. Innovations might include/consider:

<ul>
	<li>Interactive or adaptive microplans that better incorporate past or real-time data (e.g. based on prior campaign performance or operational monitoring data) to guide planning and implementation.</li>
	<li>Increased automation of microplans (e.g. updating, adapting microplans for other platforms).</li>
	<li>Modeling and analytics to test, identify, and recommend more effective implementation approaches (e.g. modeling to identify optimal location of campaign fixed sites and outreach posts in order to improve community access).</li>
	<li>Novel or nontraditional information or data sources to improve the accuracy of planning (e.g. geospatial data to improve population estimation or location and more accurately plan for and target campaign delivery).</li>
	<li>Technologies for developing and using community maps or populations that can help campaigns to better reach their intended age groups or sub-populations.</li>
	<li>Novel approaches to understanding the effectiveness of campaign planning and implementation while campaigns are ongoing or during post-campaign evaluations.</li>
</ul>

Identifying and reaching high-risk or unreached populations: This includes innovative approaches to better understand, identify, and reach un/underserved communities and unreached or "zero-dose" children. This wil likely include novel tools, technologies, and methodologies to more effectively identify and reach high-risk or unreached populations at a subnational level (e.g. approaches to leverage data, maps, or other information to support campaign planning, appropriate use of targeted or sub-national campaigns, and post-campaign assessments).

Criteria for success include solutions that:

<ul>
	<li>Are transformative, novel, or innovative. These interventions will significantly change the way in which campaigns are planned, conducted, or evaluated by proposing new ways of working, leveraging lessons from other sectors, or increasing transparency and effectiveness.</li>
	<li>Could be used by various health campaigns beyond the campaign in which the innovation is originally conceptualized or tested, such as for immunization (measles, yellow fever, meningitis, etc.), neglected tropical diseases (trachoma, onchocerciasis, schistosomiasis etc.), nutrition (vitamin A, deworming), malaria (bed net distribution, seasonal malaria chemoprophylaxis), and polio.</li>
	<li>Could be used in various low- and middle-income countries beyond the country in which the innovation is originally conceptualized or tested.</li>
	<li>Can be designed, tested, and scaled as a "best practice".</li>
	<li>Can be applied in low- and middle-income countries.</li>
	<li>Are cost effective.</li>
</ul>

We will not consider funding for:

<ul>
	<li>Proposals that are not innovative; proposals that only offer incremental / non-transformative improvements (e.g., use of mobile data collection instead of paper-based collection) with no clear link to dramatically improved campaign effectiveness; proposals that repeat conventional approaches without novel application.</li>
	<li>Proposals addressing one specific health need/campaign platform, rather than an innovation that would improve health campaigns in general.</li>
	<li>Proposals focused on educational campaigns or are not specifically focused on campaign-based delivery of health goods and services. Interventions that are better classified as technical assistance or campaign implementation (e.g., focused on the delivery or improvement of a single campaign).</li>
	<li>Proposals focused on improving access to existing tools or technologies or seeking to apply existing tools in ways that do not transform the current practices used for campaign-based delivery.</li>
	<li>Proposals where the solution is to leverage one health campaign for co-delivery of other goods or services (e.g., using a NTD campaign to deliver vaccine reminders).</li>
	<li>Approaches not directly relevant to low-income settings and that do not clearly consider the local context of available financial systems and infrastructure for resource poor health settings (e.g., using expensive devices; require government issued IDs where few people have them; require hospital deliveries in settings where this is not the norm).</li>
	<li>Secondary analysis of existing studies or systematic reviews unless there is a clear way in which the analysis can be scaled and will fundamentally change practice.</li>
	<li>Approaches that circumvent the public sector completely.</li>
