Question

What is vaccination?

Answer 1

Vaccination is the administration of antigenic material to stimulate an individual's immune system to develop adaptive immunity to a pathogen. Vaccines can prevent or ameliorate morbidity from infection.

Vaccination is when a virus, or bacteria, is deliberately administered to you (usually by injection) so that your immune system can prepare to fight a future infection.

e.g. Polio vaccine which will help your body to fight against polio virus.
