U.S. GOVERNMENT DISCLAIMER
The U.S. Government collects reports of adverse health events that follow the administration of a vaccine. This database, called the Vaccine Adverse Event Reporting System (VAERS) is available for anyone to use.
MedAlerts offers an alternative to the official VAERS search engine, CDC Wonder. Both are built from the government's raw data, but MedAlerts has a better user interface, more powerful search capabilities, and more extensive reporting, making it the best VAERS search facility.
If you suspect that you or your child has experienced a vaccine reaction, report that reaction to the government.
