A Novel Test to Measure Mucosal Immunity to Vaccines

Giulietta Saletti of the International Vaccine Institute in the Republic of Korea will work to develop an assay test that binds to tissue-specific cell markers to not only measure the concentration of anti-body secreting cells, but also identify which of those cells are targeted to mucosal tissues. If successful, this simple test that requires a small blood sample can be used in low-resource settings to measure mucosal immune responses to vaccines in infants and children.
