Ingredients 

Yes, the vaccine does not contain any animal products or egg.

If, and when, further vaccines are approved we will publish information about known allergens or ingredients that are important for certain faiths, cultures and beliefs.

These vaccines are safe and effective for the vast majority of people – they have been tested on tens of thousands of people and assessed by experts.  

Any person with a history of immediate-onset anaphylaxis to a vaccine, medicine or food should not receive the Pfizer/BioNTech vaccine. A second dose of the Pfizer/BioNTech vaccine should not be given to those who have experienced anaphylaxis to the first dose of Pfizer/BioNTech vaccination.

Everybody will also be screened for potential allergic reactions before getting vaccinated. All vaccinators will have the training they need to deal with any rare cases of adverse reactions, and all venues will be equipped to care for people who need it – just like with any other vaccine. 

The original MHRA advice was that anybody with a known allergy to specific ingredients in the vaccine should not be vaccinated. This was temporarily widened but the guidance has now reverted to this. 

Checking for allergies is a routine part of the process before giving any vaccine or new medicine. Having these conversations – as well as being able to deal with allergic reactions in the rare case they do happen, is a central part of training for vaccinators. But these are new vaccines and so the NHS and the MHRA are being extra vigilant and responding quickly to ensure everyone across the NHS is totally clear on these requirements.  

There is no material of foetal or animal origin in either vaccine. All ingredients are published in healthcare information on the MHRA’s website.

For the Pfizer/BioNTech vaccine information is available here (opens in a new window).

For the Oxford/AstraZeneca vaccine information is available here (opens in a new window).

There is no evidence to suggest that individual genetic material will undergo an alteration after receiving the vaccine
