January 22, 2021

(STAT News) – The Moderna Covid-19 vaccine, like the one made by Pfizer and BioNTech, appears to induce rare anaphylactic reactions in a small number of people who receive the vaccine, new data from the Centers for Disease Control and Prevention suggest. As of Jan. 19, there have been 15 confirmed cases of anaphylaxis after receipt of Moderna’s vaccine and 45 confirmed cases of anaphylaxis after receipt of the Pfizer vaccine, the CDC said in a statement to STAT. That works out to a rate of 2.1 cases per million doses of the Moderna vaccine and 6.2 cases per million doses of the Pfizer, according to the agency.
