Question

1. Briefly explain how vaccines work to assist your immune system tackle invaders in your system. 2a. Opinion: Do you think everyone should qualify for an HIV vaccine in childhood? Why or Why not?

Answer 1

1. Vaccines are killed or weakened germs that administered into the body. It protects against the disease by producing the antibodies against the particular antigens. When the invaders enter into the body, the lymphocytes produce antibodies against the foreign material and protects the body from infection. These antibodies remain in the bloodstream for a long time and prevent the antigen enters into the body again. In this way, the immune system tackles the invader's organisms. For example, if a child gets chickenpox, mumps, and measles once, they won't get again.

2. In my opinion, HIV vaccination is not necessary for every child. Because HIV is not a contact disease or droplet infection and It can be protected. So the transmission of HIV is controllable. Only the population with a risk of HIV virus can be immunized otherwise it is not necessary for everyone. The ultimate goal is to protect people. So vaccination is not the only way to protect the whole population.
