Emails show the Centers for Disease Control and Prevention (CDC) made a false statement on COVID-19 vaccine safety monitoring in 2021, months before agency officials gave false statements on the matter to The Epoch Times. The emails also show top officials in the agency discussing performing safety monitoring on a key database for myocarditis, a form of heart inflammation that has been linked to the vaccines from Pfizer and Moderna. The CDC promised in 2021 in a set of operating procedures to perform a type of analysis called Proportional Reporting Ratio (PRR) on reports of adverse reactions following COVID-19 vaccination. The reports are submitted to the Vaccine Adverse Event Reporting System VAERS, which officials have described as “the nation’s early warning system” for post-vaccination adverse events. The CDC also said in an updated set of operating procedures in 2022 that it would perform the analysis. But the CDC has made false statements three times this year on PRRs, initially saying such analysis was outside the agency’s purview, then saying the analysis was performed starting in 2021, then saying the analysis did not begin until 2022. The newly obtained emails show that an official falsely said the CDC does not perform PRR analysis to an editor in 2021.
