More evidence that RNA vaccines against Covid-19 are safe. The use of this new technology on such a large scale (several billion people were vaccinated worldwide in less than a year) has caused part of the population to fear the health catastrophe caused by the potential side effects of these vaccines. Fortunately, all scientific studies examining the safety of coronavirus vaccination agree that serious side effects (such as myocarditis) are rare and that vaccines are less to be feared than coronavirus infection: the risk of serious side effects after vaccination will be 55 times lower. than with the development of a severe form of Covid-19 after infection. A new study supports this notion, showing that the vast majority of side effects from RNA vaccines are mild.
The Most Robust Vaccine Pharmacovigilance System in US History
The U.S. Centers for Disease Control and Prevention (CDC) analyzed all adverse events reported following Covid-19 vaccination between December 2020 and June 2021, during which time more than 298 million doses of RNA vaccine were administered in this country (132 million from Moderna). and 167 million from Pfizer). Their analysis, published March 7, 2022 in the journal Lancet Infectious Diseasesis based on two pharmacovigilance systems: the American Vaccine Adverse Event Reporting System (VAERS) and a recent system created specifically for coronavirus vaccines called v-safe.
The first is administered by the CDC and the US Food and Drug Administration (FDA). It collects all notifications of side effects after vaccination that may come from citizens, their doctors and vaccine manufacturers. The second is a mobile phone app where vaccinated people are surveyed daily to track any negative reactions during the first week after vaccination. “Most Reliable Covid-19 Vaccine Safety Tracking in U.S. History with These Two Complementary Systems“, says the informed Dr. Hanna Rosenblum, CDC researcher and study author.
