This post in the Center for Global Health R&D Policy Assessment blog reflects on this year’s Institute Of Medicine (IOM) Annual Meeting, “Vaccines: The Science, Policy, and Practice of Immunization,” which took place on October 17. According to the blog, the event was “an opportunity to both relish recent accomplishments in immunization such as the roll out of the Meningitis A vaccine in Central Africa, the hopefully permanent drop in polio cases in India and the global increase in DTP3 coverage, and to step back and critically consider the challenges and opportunities that lie ahead in maintaining momentum for existing vaccine programs and in developing and rolling out new ones” (Rao, 10/21).
