FDA and CDC Find More COVID Vaccine Adverse Events, Including Stroke Beginning in January, documents released under the Freedom of Information Act found that the U.S. Centers for Disease Control and Prevention detected hundreds of safety signals for Pfizer and Moderna COVID-19 vaccines.
Researchers from Kaiser Permanente also reported in October that people who took the COVID boosters with the influenza vaccine were at a greater risk of stroke.
In a preprint published in April, Mr. McKernan and his team found DNA fragments in both Moderna and Pfizer vaccines that exceeded the European Medicines Agency's 330 nanograms per milligram requirement and the FDA's 10 ng/dose requirements.
COVID Vaccine-Injured People Compensated In April, the U.S. government compensated people injured by the COVID-19 vaccines for the first time.
As of Dec. 1, 10 people have been compensated for their injuries from the COVID-19 mRNA vaccines.
Mask Mandates Return in August, New COVID Vaccines Approved While no federal agencies have reinstated masking mandates, some workplaces, schools, and hospitals started bringing back mask mandates in August due to rising COVID-19 hospitalizations.
Despite the CDC's advisory board recommending the vaccine for children and adults, in a report posted on Sept. 27, it acknowledged that certainty about the vaccine's ability to prevent severe COVID, hospitalization, and death from COVID was "Low" for adults and "Very low" for children and infants.
A month later, the FDA approved the Novavax protein-based COVID vaccine to protect against COVID-19.
Final Batch of Pfizer Vaccine Documents Released by the FDA Under FOIA, the FDA released the final 51,000 pages of the Pfizer COVID-19 vaccine document.
Pfizer's COVID vaccines may have several manufacturing problems.
Not Messenger RNA but Modified RNA, Vaccines Form Aberrant Proteins While the COVID-19 mRNA vaccines on the market were advertised as messenger RNA, meaning naturally occurring RNA in the body, documents from Pfizer and studies on Moderna vaccines showed that the actual mRNA used is modified RNA, or modRNA. Naturally occurring mRNA is primarily composed of uridine, while the modRNA in vaccines has had most of the uridine switched to pseudouridine to make the vaccines hardier and more resistant to immune degradation.
