Vaccinations

A vaccination is a form of preventive medicine that involves the introduction of a weakened or inactivated form of a virus, bacteria, or other agent into the body, which acts as an exposure to the agent and induces the body to create immunity to the pathogen. Vaccinations are used to protect against infectious diseases, some of which can be fatal. They can also be used to prevent the spread of disease, ultimately eradicating it in the general population. Vaccinations are a safe and effective way to protect both individuals and communities from a number of serious illnesses.
