Your mother is worried because she heard that the chicken pox vaccine your baby brother is going to receive is weakened form of
the virus that causes the disease. How do you explain to her that being injected with the disease will actually help protect your brother? PLEASE EXPLAIN!!!
Being exposed to a weakened form of the virus allows your immune system to adapt to that virus and learn how to overcome it, without actually becoming sick. should your brother get the virus, his immune system will know how to handle it.
