Vaccine providers are encouraged to report any clinically significant health problem following vaccination to VAERS, whether or not they believe the vaccine was the cause.
Reports may include incomplete, inaccurate, coincidental and unverified information.
The number of reports alone cannot be interpreted or used to reach conclusions about the existence, severity, frequency, or rates of problems associated with vaccines.
VAERS data are limited to vaccine adverse event reports received between 1990 and the most recent date for which data are available.
VAERS data do not represent all known safety information for a vaccine and should be interpreted in the context of other scientific information.
