British media have reported that British regulators have warned that people with a history of “significant” allergic reactions should not currently receive the Pfizer / BioNTech Covid-19 vaccine after two people stung Tuesday developed allergic reactions.
The NHS in England confirmed that two NHS employees who received the vaccine on the first day of the mass vaccination program had allergic reactions.
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.
The NHS in England said it has notified all trusts participating in the vaccination plan.
This means that anyone planning to get the vaccine on Wednesday will be asked about their history of allergic reactions.
Professor Stephen Powis, national medical director for the NHS in England, said: “As is common with new vaccines, the MHRA has 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.”
The MHRA advice states: “Any person with a history of a significant allergic reaction to a vaccine, medicine or food (such as a previous history of anaphylactoid reaction or those who have been advised to carry an adrenaline autoinjector) should not receive the Pfizer/BioNtech vaccine.
“Resuscitation facilities should be available at all times for all vaccinations. Vaccination should only be carried out in facilities where resuscitation measures are available.”
Obviously, both staff have a history of severe allergic reactions – to some extent they need an adrenaline auto-injector.
They developed symptoms of “anaphylactoid reaction” shortly after vaccination, and after proper treatment they have both recovered.
