Severe Side Effects of mRNA Vaccines: Insights from Peer-Reviewed Studies
Since the introduction of mRNA vaccines, such as Pfizer-BioNTech’s BNT162b2 and Moderna’s mRNA-1273, in late 2020, they have been pivotal in combating the COVID-19 pandemic. These vaccines, which use messenger RNA to instruct cells to produce a spike protein and trigger an immune response, have demonstrated high efficacy in preventing severe illness. However, alongside their widespread use, concerns about severe side effects have prompted extensive research. This article explores major peer-reviewed studies that have investigated these rare but significant adverse events, shedding light on their nature, frequency, and implications. Myocarditis and Pericarditis: A Recognized Risk One of the most well-documented severe side effects of mRNA vaccines is myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the heart’s outer lining). A 2021 study published in JAMA analyzed safety surveillance data from the U.S. Vaccine Adverse Event Reporting System (VAERS)…
