As the title indicates, the document contains information about adverse events that occurred following vaccination, not vaccine side effects as many claimed. Pfizer’s document is titled “Cumulative Analysis of Post-authorization Adverse Event Reports of PF-07302048 (BNT162B2) received through 2”. In contrast, the term “side effect” refers only to adverse events causally linked to the vaccine, such as an allergic reaction to a vaccine ingredient. However, a toothache can’t be attributed to vaccination. For example, a toothache in someone who received a vaccine would be considered an adverse event. The term “adverse event” describes any health problem that occurs after vaccination, regardless of whether the vaccine caused it. To understand why the claims are misleading, it is important first to understand the difference between an “adverse event” and a “side effect”. What does the data in the Pfizer’s document mean? On their own, these reports don’t demonstrate that the vaccine caused the adverse event and don’t provide evidence that the vaccine is unsafe.

Such posts received more than 47,000 interactions on Facebook and Instagram, according to the social media analytics tool CrowdTangle.Ĭhildren’s Health Defense issued a related press release claiming that “The potential for serious harm is very clear” and that “It would be criminal to expose infants and young children to this extremely risky product”. One of the documents released was a 38-page safety surveillance report from the first three months post-authorization that included a nine-page appendix listing adverse events of special interest.īased on this document, multiple posts and memes (see examples here, here, and here) claimed that the Pfizer-BioNTech COVID-19 vaccine caused a lengthy list of serious side effects, ranging from epilepsy to liver injury to autoimmune diseases. The information contained in the Biological License Application was confidential and unavailable to the public until the FDA Center for Biologics Evaluation and Research released part of these data on 1 March 2022.

Therefore, these reports don’t establish a causal relationship between the events and the vaccine. Adverse events are health problems that occur after vaccination but aren’t necessarily caused by the vaccine. Food and Drug Administration contains information about adverse events that occurred following vaccination. ![]()
