What Are Vaccines and Immunizations?

Vaccines cause immunization — the process of warding off and protecting you from a range of infectious diseases that can harm you and make you sick. You can be vaccinated for a range of infections and viruses including the flu, HPV, whooping cough, polio and measles. Vaccines can be taken orally, injected and inhaled.
