Vaccines are extremely safe and harm is rare. Worldwide, more than 30000 vaccine doses are delivered per second through routine immunization programs, which, in turn, prevent an estimated 2 million to 3 million deaths annually. Yet the specter of vaccine injury plays a central role in vaccine access and will continue to do so as vaccine technologies evolve.
