Vaccination

Vaccination is a medical procedure that involves administering a vaccine to an individual to protect them against a disease. Vaccines work by exposing the body to a small, harmless version of a virus or bacteria, which triggers an immune response. This immune response causes the body to produce antibodies, which help protect against future infections with the actual virus or bacteria.

Vaccines are an important tool in preventing the spread of infectious diseases and protecting public health. They have been responsible for the eradication of diseases such as smallpox and the near-eradication of others, such as polio. Vaccines are usually given as injections, but can also be administered orally or through the nose.

There are many different vaccines available to protect against a wide range of diseases, including measles, influenza, and pneumonia. It is important to follow the recommended vaccination schedule to ensure that you are protected against these diseases.

In some cases, vaccines may have side effects, but they are generally mild and temporary. Serious side effects are rare. It is important to talk to your healthcare provider about any concerns you have about vaccination.
