Severe allergic reactions, or anaphylaxis, to the Pfizer-BioNTech COVID vaccine are rare, with around 11 cases for every million doses administered, say US scientists. During December 14 to 23, 2020, there were 1,893,360 first doses of Pfizer-BioNTech COVID-19 vaccine administered, and the CDC identified 21 case reports of anaphylaxis. Of these 21 people, four were hospitalised, and 17 were treated in an emergency department; 20 are known to have been discharged home or had recovered. No deaths from anaphylaxis were reported.
