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."
"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 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.
