The word vaccine comes from the Latin word "vacca" meaning cow. People who get vaccinations are receiving a vaccine. A vaccine is like a weakended form of a disease, that gives your body immunity against the disease by way of an antigen. These antigens work by stimulating your immune system to create antibodies against the disease. Vaccines come in the form of a needle or a liquid. Many school children receive their booster shots for tetanus, diphtheria, and pertussis between the ages of four and five, and again in grade nine.
