Biodegradable Microspheres Deliver Time Release Vaccines, Stimulate Different Immune Response
WASHINGTON, DC – February 28, 2007 -- A new vaccine delivery system using microspheres of a biodegradable polymer may not only reduce the need for booster shots in some cases, but also appears to stimulate an immune response that traditional vaccines do not. Researchers from Iowa State University report their findings today at the ASM Biodefense and Emerging Disease Research Meeting.
