Question

what is immunisation​

Answer 1

⠀⠀ ⠀ ⠀⠀ $\huge{\tt{\red{❥}\green{A}\purple{N}\pink{S}\blue{W}\orange{E}\red{R}}}$Immunisation describes the process whereby people are protected against illness caused by infection with micro-organisms (formally called pathogens). The term vaccine refers to the material used for immunisation, while vaccination refers to the act of giving a vaccine to a person.

Answer 2

Explanation:

Immunization is the process of giving a vaccine to a person to protect them against disease. Immunity (protection) by immunization is similar to the immunity a person would get from disease, but instead of getting the disease you get a vaccine. This is what makes vaccines such powerful medicine. Most vaccines are given by needle (injection) but some are given by mouth (orally) or sprayed into the nose (nasally). Immunizations are also called vaccinations, needles, shots or jabs.
