Write a short note on means of spread and immunisation
Answers
Answer:
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.
Immunity describes the state of protection that occurs when a person has been vaccinated or has had an infection and recovered.
Vaccination, like infection, confers immunity by interaction with the immune system.
The term micro-organism refers to infectious agents that can only been seen under the microscope and here covers bacteria, viruses, fungi and protozoa.
Antigens are the components/fragments from pathogens or their toxins.
