U.S. authorities are interested in patients' allergies to Pfizer vaccine

U.S. authorities are interested in an allergic reaction to a coronavirus vaccine from BioNTech/Pfizer. This was reported by a representative of the Food and Drug Administration (FDA) Peter Marks.

According to him, a chemical substance, polyethylene glycol, which is also included in the vaccine of an American company Moderna, is a possible cause of patients’ allergy to the drug. It is noted that the FDA is currently studying five cases of allergic reactions to the vaccine.

Earlier in the U.S. there was recorded a case of a severe allergic reaction to a Pfizer vaccine. The allergy developed in a nurse from Alaska ten minutes after administration of the drug. At the same time, the girl had no history of allergies reported.
