Vaccination is different from other types of medical benefits as it prevents us from diseases.
We take medicine to cure disease not to prevent the body from being diseased. But vaccination is used to prevent the body from being affected by harmful disease such as polio, hepatitis B, et cetera.
The attenuated or live form of microorganisms are injected in the body so that the body is prepared for the further attack by the microorganism.
Other medical health benefits cures the disease.
