Immunity means being protected from something and being unaffected or not bothered by it. There are two main types of immunity: innate, also called natural or inherited, and adaptive. Our immune system protects us and helps fight off disease. Microorganisms, small microscopic organisms, and viruses are everywhere.

Shots may hurt a little, but the diseases they can prevent are a lot worse. Some are even life-threatening. Immunization shots, or vaccinations, are essential. They protect against things like measles, mumps, rubella, hepatitis B, polio, tetanus, diphtheria, and pertussis (whooping cough). Immunizations are important for adults as well as children.
