These are the groups of people who can’t have the Pfizer Covid vaccine

People in the UK with severe allergies have been warned not to receive the Pfizer/BioNtech vaccine.

The Medicines and Healthcare products Regulatory Agency (MHRA) gave out the advice after two NHS workers had an allergic reaction to the jab.

Both people, who have recovered, have a history of serious allergies and need to carry adrenaline pens around with them.

So, who should not be vaccinated? There are currently three types of people who should avoid the jab - here’s what you should know.

Who can’t be vaccinated?

People with allergies

After the NHS workers had an allergic reaction, the MHRA said their temporary warning applied to anyone who has had reactions to medicines, food or vaccines in the past.

That includes anyone that has experienced a reaction so severe that they have been prescribed an EpiPen adrenaline injection.

The two workers had an anaphylactoid reaction, which often involves a skin rash, breathlessness and a drop in blood pressure, and is different to anaphylaxis which can be fatal.

The specific reason for the NHS staff members’ allergic reaction remains unclear.

People with all severe allergies have been told not to be immunised because those who are allergic to one thing are often prone to react to new allergens.

Healthcare professionals have also been told that the vaccine should not be given to people with any allergy to the vaccine’s ingredients.

However, the ingredients don't include anything that commonly provokes allergic reactions from vaccines, like eggs or gelatin.

Reactions to vaccines are not uncommon, and can happen with others like the annual flu jab.

Pregnant women

Pregnant women have also been told that they can’t get a vaccine, because there is currently no data about any potential risks.

The Joint Committee on Vaccination and Immunisation (JCVI) recommended that pregnant women should not opt to receive the jab.
