Vaccines are used to stimulate the immune system into producing antibodies, so that the individual is thereafter protected from the disease.  Some vaccines have lifelong effects, and others may need to be repeated.

Sites listed here will represent companies which develop and/or manufacture vaccines for use in humans and animals.  If the primary focus is on animal health, please submit to the Veterinary subcategory.
