December 9, 2020 | The U.K.'s Regulatory Agency is advising people with a history of "significant" allergic reactions to avoid Pfizer's coronavirus vaccine, after two National Health Service members developed severe allergic reactions to it on Tuesday (Dec. 8).
"As is common with new vaccines the MHRA (Medicines and Healthcare products Regulatory Agency) have advised on a precautionary basis that people with a significant history of allergic reactions do not receive this vaccination after two people with a history of significant allergic reactions responded adversely yesterday," Stephen Powis, the national medical director for England's National Health Service said in a statement on Wednesday (Dec. 9).
Both workers have a history of severe allergies and carry adrenaline auto injectors (such as EpiPens) around with them, according to The Guardian. Shortly after receiving the vaccine, both NHS workers developed anaphylaxis-like symptoms, or severe allergic reactions, but have recovered after receiving treatment.
