According to an interim report from Sen. Ron Johnson’s office, CDC and FDA officials knew in 2021 about the potential risks of heart-related complications, such as myocarditis, from the experimental COVID-19 jabs and hid the knowledge from the public for months. “Even though CDC and FDA officials were well aware of the risk of myocarditis following COVID-19 vaccination, the Biden administration opted to withhold issuing a formal warning to the public for months about the safety concerns, jeopardizing the health of young Americans,” the report alleges, according to the New York Post. The report alleges that federal health officials knew about substantial reports of myocarditis in February 2021 and waited until June of that year before making the risk known. JUST IN – CDC and FDA officials were well aware of the risk of myocarditis following mRNA injections — and took steps to downplay them, scathing Senate report says. pic.twitter.com/aOFCFgA0r0 — Disclose.tv (@disclosetv) May 21, 2025 From the New York Post: On Feb. 28, 2021, an Israeli Ministry of Health official attempted to contact the CDC and Food and Drug Administration (FDA) about 40 cases of myocarditis and other heart-related ailments in young people from the Pfizer vaccine. At the time, Israel had a much higher vaccination rate than the US, the report noted. About 10 days later, an FDA official drafted a response noting that “limitations of passive surveillance … [and] incomplete data make it challenging to assess causation.” US health officials requested more data from the Israelis. By mid-April, a Defense Department contractor involved with the Pentagon’s work on immunization delivered a presentation to the COVID-19 Vaccine Safety Technical (VaST) working group that concluded “there is a high likelihood that cardiac symptoms following COVID-19 vaccination represent a hypersensitivity eosinophilic myocarditis.” By this time, there had been more than 158 cases of myocarditis, pericarditis, or myopericarditis reported on the Vaccine Adverse Event Reporting System (VAERS). The following month, the COVID-19 vaccine was approved for adolescents, and members of VaST “felt that information about reports of myocarditis should be communicated to providers.” “Top federal health officials actively took steps to ‘delay warning the public’ for months in 2021 about the potential risks of heart-related complications from receiving mRNA COVID-19 vaccines, a scathing interim report from Sen. Ron Johnson’s office alleges.

The FDA is requiring COVID vaccine makers Pfizer and Moderna to update their warnings about the possible risk of myocarditis and pericarditis. https://t.co/KWQ2WpuBI6 — CBS News (@CBSNews) May 21, 2025 CBS News reports: Orders to expand the warnings were posted Wednesday by the FDA, in letters dated April 17 to Pfizer and BioNTech about their Comirnaty vaccine and Moderna about its Spikevax vaccine. Both vaccines previously carried warnings about how the risk of the heart side effects — which doctors call myocarditis (an inflammation of the heart muscle) and pericarditis (inflammation of the membrane surrounding the heart) — looked to be higher in young men, generally within the first week after vaccination. While the earlier labels specified ages 18 to 24 years old for Moderna’s vaccine and 12 to 17 years old for Pfizer’s, the new warning will apply to males ages 16 to 25 for both vaccines. “Following administration of the 2023-2024 Formula of mRNA COVID-19 vaccines, the highest estimated incidence of myocarditis and/or pericarditis was in males 16 through 25 years of age,” the FDA says in the new blanket warning it will require for both vaccines. The rate of myocarditis and pericarditis was around 8 cases per million doses for children and adults under 65 years old after use of that season’s vaccines, the FDA says.
