Question

What is the difference between vaccination and immunization.

Answer 1

Vaccination is when a vaccine is administered to you (usually by injection). Immunisation is what happens in your body after you have the vaccination. The vaccinestimulates your immune system so that it can recognise the disease and protect you from future infection (i.e. you become immune to the infection).

Vaccination is the administration of a weakened form the virus to allow the body to become immune to the disease.
Immunization is the process whereby a person is made immune or resistant to an infectious disease, typically by the administration of the vaccine.
