The 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 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.
