Information about Vaccine Safety
Vaccines are extremely safe and work best when most members of a community are vaccinated. Because vaccines must be safe for use by as many people as possible, vaccines are developed in accordance with the highest standards of safety. Years of testing are required by law before a vaccine is licensed and distributed in the United States. Once licensed and in use, vaccines are continuously monitored for safety and efficacy. Not surprisingly, the United States currently has the safest, most effective vaccine supply in history.
