Vaccine Components

Vaccines contain antigens that prompt the body to create antibodies. The antibodies fight the germs that cause the disease the vaccine is intended to prevent. In addition to antigens, vaccines contain other ingredients or additives used in the production process. These additional ingredients are used to purify, stabilize and preserve, increase the effectiveness of the vaccines, and/or create the vaccine.
