Members of some religious communities may be concerned about using vaccines that contain gelatine from pigs.
The UK Health Security Agency (UKHSA) spoke to the Kashrut and Medicines Information Service, who said:
‘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.’
Some Muslim leaders have also ruled that the use of gelatine in vaccines does not break religious dietary laws, because it is highly purified, and it is also injected or inhaled rather than eaten.
