The correct option is 4)  Killers or inactive pathogen insert into human body

Explanation:

• Vaccination can be described as a process in which weakened or killed pathogens are injected into a human body.

• The process is done so that the immune system of the individual make memory cells against that particular pathogen. As the pathogen is weakened or already killed, it wont have harmful effect on the body.

• However, when that particular pathogen invades the body, the immune cells will immediately recognize it and produce a much faster immune response against it.
