Detailed explanation-1: -Live-attenuated vaccines Because these vaccines are so similar to the natural infection that they help prevent, they create a strong and long-lasting immune response. Just 1 or 2 doses of most live vaccines can give you a lifetime of protection against a germ and the disease it causes.
Detailed explanation-2: -The immune response to a live, attenuated vaccine is virtually identical to that produced by a natural infection because the immune system does not differentiate between an infection with a weakened vaccine virus and an infection with a wild NOTES Page 5 Principles of Vaccination 5 1 virus.
Detailed explanation-3: -Modified live virus (MLV) vaccines are effective because they provide the same immunity (cellular, humoral, systemic, and local) produced by natural exposure (2). Properly immunized animals have sterilizing immunity that not only prevents clinical disease but the presence of antibody also prevents infection.
Detailed explanation-4: -Vaccination protects the vaccinated persons and those around them who are vulnerable to the diseases, reducing the risk of diseases spreading among family members, school mates or colleagues, friends, neighbours and other people in the community.
