Question

write a short note on vaccination?​

Answer 1

Answer:

Vaccines provide immunity from infectious diseases like tetanus, diphtheria, whooping cough, measles, polio etc. Our body has an immune system which fights microbial infection. When this system first sees an infectious microbe, it kills the microbe and remembers it.

Vaccination is a scientific system of developing human immunity without infection. The weakened or killed pathogens are injected into the body through the vaccination that builds immunity against the particular pathogen. This pathogen produced antibodies in the body.
