People with a history of significant allergic reactions should not have the Pfizer/BioNTech Covid jab.

The advice comes as two NHS workers had allergic reactions.

The Medicines and Healthcare products Regulatory Agency advice applies to those who have had reactions to medicines, food or vaccines.

The MHRA advice states: “Any person with a history of a significant allergic reaction to a vaccine, medicine or food (such as 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.”

The two people had a reaction shortly after having the new jab, had treatment, and are now both recovering.

It is reported that they had an anaphylactoid reaction, which tends to involve a skin rash, breathlessness, and sometimes a drop in blood pressure.

Both workers are understood to have a history of serious allergies and carry adrenaline pens around with them.

Professor Stephen Powis, medical director for the NHS in England, said both individuals are recovering well.

“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,”
