NEW YORK, Jan 27 (Reuters) - The U.S. Centers for Disease Control and Prevention (CDC) said on Wednesday it is observing a lower rate of severe allergic reactions in people in the United States who have received Pfizer Inc and BioNTech SE’s COVID-19 vaccine.
The CDC said that through Jan. 18, there were 50 cases of anaphylaxis reported in recipients of the vaccine. That implies a rate of about 5 per million doses administered, down from its previously reported rate of 11.1 per million doses administered through Dec. 23.
It reported 21 cases of anaphylaxis after Moderna Inc’s COVID-19 vaccine was administered. That implies a rate of 2.8 cases per million doses, up slightly from the previously reported rate of 2.5 per million doses, based on data through Jan. 10. (Reporting by Michael Erman Editing by Chizu Nomiyama)
