How does a person become immune to a viral disease by medical treatment/natural process?
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 ur body from the disease the first timewhich is why u 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 dont get teh disease because the vaccine is a weak strain of the disease anayway. And you dont get the disease because the antibodies stay on in your blood stream and prevent you from being attacked by that disease. LO!!
