The national medical director for NHS Stephen Powis noted that "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” and added that the two health care workers "are recovering well."
Additionally, MHRA advised people with a history of significant allergic reactions to contact the health care professionals before receiving the coronavirus vaccine.
