Our site has a more streamlined user interface and a more powerful search and reporting faciltity. Medalerts is the best VAERS search engine on the web.

Reporting Vaccine Damage If you suspect that you or your child has experienced a vaccine reaction, report that reaction to the government at the Vaccine Adverse Events Reporting System. Due to reporting of adverse events, the rotavirus vaccine was removed from the market for causing bowel obstructions in infants and children. You can also report a reaction to the National Vaccine Information Center. We have kept a vaccine adverse event database since 1982. To report a reaction to NVIC, click here.
