UK regulators have issued a warning that people who have a history of “significant” allergic reactions should not currently receive the Pfizer/BioNTech Covid-19 vaccine.
The warning comes after two NHS staff members who received the Pfizer/BioNTech vaccine suffered an allergic reaction, the NHS in England has confirmed.
Both are recovering, it is understood - the Mirror UK reports.
The NHS in England said all trusts involved with the vaccination programme have been informed.
The Medicines and Healthcare products Regulatory Agency (MHRA) has given precautionary advice to NHS trusts that anyone who has a history of "significant" allergic reactions to medicines, food or vaccines should not receive the vaccine.
Professor Stephen Powis, national medical director for the NHS in England said: "As is common with new vaccines the MHRA 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. Both are recovering well."
