The Centers for Disease Control and Prevention (CDC) confirmed that the first 22 million Americans had been vaccinated against COVID-19 at a meeting on January 27, marking another milestone in the tumultuous rollout of the vaccine in the country .
Presentation from the CDC Advisory Committee on Immunization Practices The data on vaccine safety earlier this week, where he noted that 23.5 million doses of COVID-19 had been administered nationwide as part of the “most intense and most intense vaccine safety surveillance program. complete story ”.
Additional safety data revealed that COVID-19 vaccines approved by the Food and Drug Administration mainly caused moderate side effects, such as pain at the injection site, fatigue, fever, and headache within a week of inoculation.
“The safety profiles of COVID-19 vaccines are reassuring and consistent with those seen in pre-authorization clinical trials,” the report said.
Examining a database referred to as the Vaccine Safety Database, committee researchers reported “no signals” of serious adverse side effects, including seizures, heart attacks, and other reactions. serious in vaccinees included in the database.
Anaphylaxis, or severe allergic reactions, was noted early on as a potential side effect in patients with a history of allergies. Based on data from the CDC’s vaccine adverse event reporting system, 71 people have reportedly had an allergic reaction after a vaccination.
This event was still rare, with five anaphylactic responses occurring per million doses of Pfizer vaccine administered and only 2.8 allergic episodes estimated per million doses of Moderna vaccine.
About 90% of individuals observed reported allergic reactions within the first 30 minutes after vaccination.
The committee also looked at patient outcomes specifically for residents of long-term care facilities, one of the most dangerous environments for a COVID-19 outbreak. Among the 1.3 million doses of COVID-19 vaccine administered in long-term care facilities, 11,440 deaths were reported during the same period, between December 21 and January 18.
The researchers point out, however, that “mortality in LTCFs [long-term care facility] residents is high and a substantial number of deaths in this population will occur after vaccination as time-associated coincident events ”, meaning that there is no direct relationship between deaths and vaccination against COVID-19.
The overall results indicate that COVID-19 vaccinations are safe to administer and that more data-centric measures to monitor vaccinated populations will be needed moving forward.
President Biden’s goal is to have 100 million Americans vaccinated against COVID-19 within the first 100 days of his presidential term, setting a rough deadline of April 29, 2021.
Novavax, Johnson & Johnson and AstraZeneca have all made recent progress in announcing successful clinical trial data and gaining approval in some regions. Pfizer and Moderna are also on track to manufacture millions of additional doses to supply states as part of Biden’s push for a more regular deployment.
