Gelatine in the Nasal Flu Vaccine

Expand All

The nasal flu spray protects you from getting the flu. It prevented 44% of flu cases in children during the 2018/19 season.

It also protects people around you by preventing you from spreading the virus, especially to older people and babies.


Gelatine from pork is a common ingredient in drugs including the nasal flu vaccine.

It is a stabiliser that helps to keep the vaccine safe and effective during storage.

The gelatine used in vaccines is different from that in foods as it highly processed and broken down into small fragments.

It would take years of tests to find an alternative stabiliser.

From the Kashrut and Medicines Information Service

"It should be noted that according to Jewish laws, there is no problem with porcine or other animal derived ingredients in non-oral products. This includes vaccines, including those administered via the nose, injections, suppositories, creams and ointments."


 Statement from the Muslim Council of Britain

"Vaccines containing porcine are not permitted in Islam UNLESS lives are at risk and there are no alternatives. Our view is not that Muslims should automatically refuse such treatment. Health is paramount, anyone concerned about the use of gelatin in vaccines must consult a medical practitioner and make an informed decision."


The inactivated flu vaccine can be given as an alternative to the nasal flu vaccine. This option can be discussed with your GP.


The final decision about whether or not to be vaccinated, or to have your children vaccinated, is yours.

If you would like further information before making your decisions about vaccinations, you may wish to talk to your doctor or practice nurse. More information including allergies and dietary preferences can be found on this website.
