Vaccinations are an important step in protecting against serious, and sometimes deadly, illnesses like the flu, measles, and tuberculosis. They help reduce the risk of infection by working with the body’s natural defenses to help it safely develop immunity to diseases. When germs invade the body, they attack and multiply. This invasion is called infection, which then leads to illness. After fighting the infection, the body is left with a supply of cells that help recognize and fight future diseases.
