Question

Immunity of vaccination lasts throughtout life of which of the following?

• A. Mumps vaccine
• B. Measles vaccine
• C. Small pox vaccine
• D. Cholera vaccine
• E. Both A and B

Answer 1

The correct option is E Both A and B

Live, attenuated vaccines contain a living microbe that has been weakened in the lab so it cannot cause disease. Because a live, attenuated vaccine is the closest thing to a natural infection, these vaccines elicit strong cellular and antibody responses and often confer lifelong immunity with only one or two doses. Vaccines against measles, mumps, and chickenpox, for example, are made by this method.

So, the correct answer is option E.
