The steps of vaccination are:
A weakened or dead form of the pathogen is injected into the body
↓
The pathogen is not strong enough to cause disease but its presence in the body signals the body to protect itself against the pathogen
↓
White blood cells produce antibodies that destroy the pathogen
↓
Pathogens enter the body and the body can remember the pathogen using memory cells, destroying the pathogen
Vaccination may be defined as a process through which a dead or inactivated form of a pathogen is injected into the body for the purpose of stimulating the immune system.
What do you mean by Pathogens?
Pathogens may be defined as those microorganisms which are responsible for the causation of diseases.

- A weakened or dead form of the pathogen is injected into the body.
- The pathogen is not strong enough to cause disease but its presence in the body signals the body to protect itself against the pathogen.
- White blood cells produce antibodies that destroy the pathogen.
- Pathogens enter the body and the body can remember the pathogen using memory cells, destroying the pathogen. (Secondary infection).
Therefore, it is well described above.
