the action of making a person or animal immune to infection, typically by inoculation


SpellreacterRE: Immunisation protects children (and adults) against harmful infections before they come into contact with them in the community.

Immunisation uses the body’s natural defence mechanism - the immune response - to build resistance to specific infections. Nine diseases can be prevented by routine childhood immunisation - diphtheria, tetanus, whooping cough, poliomyelitis (polio), measles, mumps, rubella, Haemophilus influenzae type b (Hib) and hepatitis B.

fatimamahveen11: i can't understand this i can't mark you as branliest sorrryyyyy
SpellreacterRE: ok
SpellreacterRE: For certain infectious diseases like measles or mumps, once a person has had them and recovered they are almost certain never to catch that disease again. This is because when you get an infectious disease your body makes antibodies against that disease which means that if you are ever exposed to it again - your antibodies in your blood will kill off the bugs before they have any effect
SpellreacterRE: is this understandable

When a vaccine is used to kill the microbes of prevent their entry into the body, the immune power of the body increases. therefore, the mechanism of developing immune power in the body to fight against diseases known as immunisation.

 (MMR) vaccine and the varicella (chickenpox) vaccine are examples of the immunisation.. 

hope it helps :)
