UK Regulator Issues Allergy Warning on Pfizer Vaccine

“Any person with a history of anaphylaxis to a vaccine, medicine or food should not receive the Pfizer BioNTech vaccine. A second dose should not be given to anyone who has experienced anaphylaxis following administration of the first dose of this vaccine,” said June Raine, chief executive of the Medicines and Healthcare products Regulatory Agency (MHRA).

Earlier it had warned that people with a “significant allergic reaction” to those things should not take the shot, without specifying anaphylaxis.
