WORLD IMMUNIZATION DAY

The theme for World Immunization Day 2022 is "Long Life For All"

immunization is a way to make you immune to a disease, specifically by taking a vaccine. Immunization (or vaccination) protects people from disease by introducing a vaccine into the body that triggers an immune response, just as though you had been exposed to a disease naturally.

World Immunization Day is celebrated on November 10 every year. It is celebrated in order to spread awareness about the benefits of getting vaccinated and how it can prevent a plethora of diseases in the long run.

A vaccine is a biological preparation that provides active acquired immunity to a particular infectious or malignant disease.

In India, most of the major diseases causing infections like tuberculosis, polio, hepatitis b, diphtheria, pertussis, tetanus, influenza, measles, and mumps are covered under the national immunization schedule. Rota viral vaccine and vaccines against pneumonia are also recently included in our national vaccine schedule.

Vaccines contain antigen which is either killed, inactivated, or attenuated. On entering the human body it stimulates the immune system to produce protective antibodies. The antibody production increases on subsequent doses and also with subsequent infections by immunological memory.
