Asked by Topperlearning User | 09 May, 2016, 07:51: AM
Expert Answer
Vaccine is any germ or germ substance introduced into the body for developing resistance to a particular disease. On injecting a vaccine into the body, the person gets the disease in mild form and his body gets stimulated to produce antitoxins. These antitoxins provide immunity against any future attack of the particular disease-causing germ.
