Coronavirus Watch: Severe allergic reactions to vaccines still 'rare,' CDC says


Severe allergic reactions to COVID-19 vaccines are still extremely uncommon.

In a pool of nearly 1.9 million first doses of the Pfizer-BioNTech vaccine administered in the U.S., there were 21 cases of a severe allergic reaction, the Centers for Disease Control and Prevention said Wednesday.

More than 81% of them occurred in people with a history of allergies or allergic reactions, and most of the patients who reported having a severe reaction – 90% – were women.

"This is still a rare outcome," said Dr. Nancy Messonnier, director of the CDC's National Center for Immunization and Respiratory Diseases. "We all would hope that any vaccine would have zero adverse events, but even at 11 cases per million doses administered – it’s a very safe vaccine." Read more.
