What is "vaccination"?
Vaccination refers to the process of giving a vaccine to help the immune system develop protection against specific diseases. Vaccines typically contain a small, harmless piece of the virus or bacteria that causes the disease, which stimulates the immune system to recognize and fight the actual germs if it enters the body in the future. Vaccination is an important tool in preventing infectious diseases, reducing the spread of illnesses, and protecting public health. It can be given through injections, nasal sprays, or oral doses, depending on the vaccine.
