Question

What is immunisation?

Answer 1

Immunization is the technique of generating immunity to an infectious organism or agent in a person or animal. Immunization-inducing vaccine. Diphtheria, polio, tetanus, measles, mumps, and rubella vaccines are included in a recommended immunisation plan for newborns and young children.

Complete answer:
The procedure of administering a vaccine to a person in order to protect them from disease is known as immunisation. Immunity (protection) from immunisation is similar to immunity from disease, except that instead of acquiring the disease, you get a vaccine.
This is why vaccines are such effective medicines. The majority of vaccines are administered via needle (injection), although others are administered via mouth (orally) or nasal spray (nasally). Immunizations, needles, shots, and jabs are all terms used to describe vaccinations.
Vaccines are made from the same bacteria that causes sickness. The germs in the vaccine, on the other hand, have been killed or weakened so that they do not cause you to become unwell. Some vaccines only contain a portion of the disease-causing bacterium.
Your body is fooled into believing it has been infected with the disease when you are inoculated. Antibodies are produced, which kill pathogens. These antibodies last a long time in your body and remember how to fight germs. If the disease's germs enter your body in the future, the antibodies will destroy them before you get sick. Getting a vaccine is far safer than contracting the disease.

Note: After being inoculated, the majority of persons are entirely protected against the disease. People who have been inoculated may still contract the disease in rare situations because the vaccination only provides limited protection.
