CDC officials made the request, which turned out to be wrong in response to a Freedom of Information Act (FOIA) report request from a CDC team focused on examining the risk of post-vaccination myocarditis and pericarditis, two forms of heart inflammation. Both began to be detected at higher than expected rates following vaccination against COVID-19 in spring 2021.
The team is focused on studying data from the Vaccine Adverse Event Reporting System (VAERS), a passive surveillance system co-operated by the CDC and the US Food and Drug Administration.
The date range for the search was April 2, 2021 to October 2, 2021.
“The National Center for Emerging Zoonotic Infectious Diseases searched our records that he did not disclose any documents related to his request”, said CDC Archives Manager Roger Andoh. The center is part of the CDC.
No abstract or report was available because “an association between myocarditis and COVID-19 mRNA vaccination was not known at the time,” Andoh added.
The Pfizer and Moderna COVID-19 vaccines are based on messenger RNA (mRNA) technology.
First reports of myocarditis
Reports of heart inflammation after COVID-19 vaccination were first made public in April 2021 by the US military, which detected the problem with the Israeli authorities long before the CDC.
While CDC Director Dr. Rochelle Walensky said that month the agency had looked for a safety signal in its data and found none, in late June, CDC researchers they said that the available data “suggest an association with vaccination” and in August described ( pdf ) the problem as an “evil” of vaccination.
The claim that the link was unknown “is probably false,” Barbara Loe Fisher, co-founder and president of the National Vaccine Information Clearinghouse, said by email. “Either the right hand doesn’t know what the left hand is doing at the CDC, or federal health officials are spreading the wrong information about what they knew about myocarditis after the COVID mRNA vaccines and when they knew it. “
Sen. Ron Johnson (R-Wis.) said that FOIA’s response “raises even more questions about the honesty, transparency, and use, or lack of use, of its security monitoring systems, such as VAERS, to detect Adverse events of injection of COVID-19. .”
“I sent Of cards to the CDC about the agency’s inability to find records showing its use of vaccine monitoring systems. To date, the CDC has not responded to my letters,” he added.
