The U.S. Centers for Disease Control and Prevention (CDC) is refusing to release updated information on reported cases of myocarditis and pericarditis following COVID-19 vaccination.
COVID-19 vaccines can cause the inflammatory conditions, the CDC has confirmed previously.
The agency has regularly conveyed the number of post-vaccination myocarditis and pericarditis cases to the Vaccine Adverse Event Reporting System (VAERS), which it helps manage, as it has consulted with its advisers on updates to the vaccines.
But during a meeting on Sept. 12, the CDC did not mention VAERS data.
Asked for the information, a CDC spokesman pointed to a CDC study that covers data only through Oct. 23, 2022.
That study identified nine reports of myocarditis or pericarditis following vaccination with one of the bivalent COVID-19 vaccines, which were introduced in September 2022. Seven of the reports were verified by medical review.
Asked for more current data, the spokesman acknowledged the agency has it but is not making it public.
“When appropriate, the updated safety data will be published,” the spokesman told The Epoch Times in an email.
He did not answer when asked why the meeting was not an appropriate time.
“The CDC has acknowledged that heart inflammation is a complication of mRNA COVID-19 shots and, yet, the only published data released by CDC officials about that complication is a seven week study that ended on Oct. 23, 2022. Where is more specific myocarditis/pericarditis data related to bivalent COVID shots for the past 10 months?” Barbara Loe Fisher, co-founder and president of the National Vaccine Information Center, told The Epoch Times via email.
The mRNA shots are made by Pfizer and Moderna. Novavax’s updated shot, which uses different technology, has not yet been authorized by the U.S. Food and Drug Administration (FDA).
“I am tired of the CDC and FDA deciding what information the public needs and doesn’t need. This is precisely the information that parents need to have especially when there are still schools and activities mandating these shots. This is evil playing out right before our eyes,” Kim Witczak, a drug safety advocate who runs the nonprofit Woodymatters, told sources in an email.
She added, “The CDC’s response of ‘when appropriate, the updated safety data will be published’ is unacceptable and they wonder why there is vaccine hesitancy and lack of trust in public health officials.”
During the recent meeting, CDC officials and their partners presented data on the bivalent shots to their advisory panel, the Advisory Committee on Immunization Practices. The advisers were considering which groups should be recommended to get one of the new COVID-19 vaccines, which were cleared by regulators with scant clinical trial data.
Dr. Nicola Klein, a Kaiser Permanente doctor who works closely with the CDC, gave a presentation (pdf) on COVID-19 vaccine safety. She presented data from the Vaccine Safety Datalink, a monitoring system that covers a much smaller population than VAERS.
Dr. Klein said that two cases of myocarditis after bivalent vaccination were detected in the Vaccine Safety Datalink (VSD) through March 11. It’s not clear why more current data were not presented. Dr. Klein did not respond to a request for comment. The cases did not trigger a safety signal among adults, Dr. Klein said.
The presented data were widely cited by doctors quoted in news outlets, including Dr. Andrew Pavia, who told a briefing that there did not appear to be a “detectable risk” of the bivalent shots causing myocarditis.
