The top U.S. public health agency identified hundreds of safety signals for the Pfizer and Moderna COVID-19 vaccines months earlier than previously known, according to files obtained by The Epoch Times.
The U.S. Centers for Disease Control and Prevention (CDC) found more than 700 signals that the vaccines could cause adverse events—including acute heart failure and death—in May 2022, the files show.
The CDC detected many of the same signals in July 2022, The Epoch Times previously reported. The new files show that the first time the CDC calculated a proportional reporting ratio (PRR) on vaccine injury reports, signals were identified.
The analysis went over reports lodged between Dec. 14, 2020, and May 6, 2022.
The CDC initially claimed that it didn’t run the PRR, a data mining method, on the injury reports made to the Vaccine Adverse Event Reporting System. The CDC later claimed that it started the method in February 2021, shortly after the vaccines were rolled out. Both of those claims were false, the CDC ultimately said, adding that it didn’t start until March 2022.
When the first analyses were done that month, CDC employees identified more than 200 signals for Pfizer’s shot and 93 signals for Moderna’s vaccine, the files show. Those analyses compare the events lodged after receiving one vaccine with events lodged after receiving another, or several others.
The Epoch Times obtained the files through Freedom of Information Act requests.
The strongest analysis involves comparing the reports lodged after vaccination with the Pfizer and Moderna COVID-19 vaccines with the reports lodged after vaccination with all non-COVID-19 vaccines. The analysis is contained in files labeled “Table 5.”
According to the files provided by the CDC, the agency didn’t start that analysis until May 2022.
“The program staff advises that ‘Table 5 was only created from May 6, 2022, to July 31, 2022,’” a CDC Freedom of Information Act processer told The Epoch Times via email.
The CDC didn’t respond to a request for more information.
