Institute for Vaccine Safety

The Institute for Vaccine Safety was established in 1997 in the Department of International Health at the Johns Hopkins University School of Public Health - now the Johns Hopkins Bloomberg School of Public Health.

Our mission is to provide an independent assessment of vaccines and vaccine safety to help guide decision makers and educate physicians, the public and the media about key issues surrounding the safety of vaccines. The institute’s goal is to work toward preventing disease using the safest vaccines possible.
