Im not sure if you can becum immmune against a viral disease but for th other kinds of diseases, when you get a disease like say chicken pox, your body produces a number of antibodies which try to protect you from acquiring that disease but they obviously cant defend your body from the disease the first timewhich is why you get it..but most of the cases, you cant ever get it again, because the antibodies produced the first time stay on and prevent repeated attacks frm chicken pox. This is natural immunisation. When a doctor injects you with a vaccine, what he's actually doin is releasing the weakened form of the disease he's protecting you against.
When this happens again your body produces antibodies for this disease and you don't get teh disease because the vaccine is a weak strain of the disease anayway. And you don't get the disease because the antibodies stay on in your blood stream and prevent you from being attacked by that disease. LO!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
