“Established in 1990, the Vaccine Adverse Event Reporting System (VAERS) is a national early warning system to detect possible safety problems in U.S.-licensed vaccines.” VAERS is a passive reporting system- meaning it relies on individuals to send in reports to VAERS. This includes patients and parents, not just doctors.
Healthcare providers are required by law to report any event listed in the VAERS Table of Reportable Events to VAERS, as well as any adverse events listed by the vaccine manufacturer as a contradiction to further doses of the vaccine.
Although vaccine manufacturers hold no liability to claims of injury- including death, as per the 1986 National Childhood Vaccine Injury Act, vaccine manufacturers are required to report all adverse events brought to their attention.
