World Council For Health

This report was prepared by the World Council for Health (WCH). The report was prepared to determine whether sufficient pharmacovigilance data exists on WHO VigiAccess, CDC VAERS, EudraVigilance, and UK Yellow Card Scheme to establish a safety signal on Covid-19 vaccines. 

These databases are not normally used to establish the safety of an intervention. However, Covid-19 vaccines are in Phase 3 trials, and their safety and efficacy have not yet been established. The majority of those who have received the intervention (several billion people) are not being monitored by the trials. In this report, the WCH aims to use these established pharmacovigilance databases to detect if there is a concerning safety signal in those not being monitored by the clinical trials.

This report collates pharmacovigilance data about Covid-19 vaccines and other commonly administered interventions from these databases. It collates data about the types of adverse event reports linked to Covid-19 vaccines on these databases. Using data from VAERS, FAERS, and historical records, the report collates data about the rate of adverse events that have been sufficient for product recall in the past.
