The U.S. Centers for Disease Control and Prevention (CDC) has identified hundreds of safety signals for the two most widely administered COVID-19 vaccines, according to monitoring results obtained by The Epoch Times.
Bell’s palsy, blood clotting, and death were among the signals flagged through analysis of adverse event reports submitted to the Vaccine Adverse Event Reporting System (VAERS). The CDC, which runs VAERS with the U.S. Food and Drug Administration (FDA), describes it as “the nation’s early warning system” for vaccine issues.
The CDC’s primary analysis compared the reports made for specific events suffered after receipt of a Moderna or Pfizer COVID-19 vaccine to the reports lodged following vaccination with any other vaccine, or all non-COVID-19 vaccines. The type of analysis is known as Proportional Reporting Ratio (PRR).
Safety signals mean a condition may be linked to a vaccine. Signals require further analysis to confirm a possible link.
The CDC analysis was conducted on adverse events reported from Dec. 14, 2020, to July 29, 2022.
The Epoch Times obtained the results through a Freedom of Information Act request after the CDC refused to make the results public.
VAERS is a passive reporting system that accepts reports from anybody, but most are lodged by healthcare professionals, who were told during the pandemic they were required to lodge reports if post-vaccination issues cropped up. People who lodge false reports face penalties.
Reports don’t prove causality or a link between an event and a vaccine. At the same time, studies show that the number of reports is often an undercount of the actual occurrence of post-vaccination events.
‘Onus Is on the Regulators’
The CDC and FDA said in operating procedure documents that officials would monitor VAERS to identify “potential new safety concerns for COVID-19 vaccines,” with the CDC performing PRR analysis. The CDC has issued multiple false statements on the data mining, but ultimately acknowledged it didn’t start performing the monitoring technique until 2022—more than one year after the Pfizer and Moderna vaccines were authorized.
