Vaccination is one of the most effective ways to prevent diseases. A vaccine helps the body’s immune system recognize and fight pathogens like viruses or bacteria, keeping us safe from the diseases they cause. Vaccines help your immune system fight infections faster and more effectively.
Receiving a vaccination sparks your immune response, helping your body fight off and remember the germ so it can attack it if the germ ever invades again. And since vaccines are made of very small amounts of weak or dead germs, they won’t make you sick.
