Answer 2

Answer:

vaccines are weaker or dead form of a virus or a disease causing micro organism which are used to prevent the a critical effect if we get infected in the future by these disease causing organism

Explanation:

The concept is that once the weaker form is injected  to our body our immune system will react and it may cause a small fever to some people and our immune system will remeber what to do when this microb or virus enter our body again...when it enters again our immune system will act vigorously thus preventing further critical issues.
