Needle-Free Delivery of Stable, Respirable Powder Vaccine
Many serious infections, such as the measles virus, can enter the body through inhalation. Vaccine delivery systems that can target respiratory mucosal tissue and stimulate immune response there have the potential to be particularly effective against these types of infections. Collaborating with an international group that includes the Serum Institute of India (SII), the U.S. Centers for Disease Control and Prevention (CDC), the University of Colorado, and private companies, Dr. Sievers and his colleagues at Aktiv-Dry, LLC (AD) are developing a dry-powder version of the measles vaccine that can be inhaled through a disposable plastic device.
