The most common role of a virus in making vaccines is injection of a live weaken form of the virus. This virus will reproduce poorly once inside the body.
When you get infected with HIV, the virus enters your blood and gets inside your cells that are floating around
It can outbreak all over the body and happen again
Vaccines contain an inert or inactive version of a virus. When the body detects it, it develops anti-bodies to the inert virus in the vaccine. So when the real virus shows up, the body recognizes it, and can easily defeat it.
I'm not sure this is also for bacteria, but when a virus enters a host, it travels to a nearby cell and attaches to it and fuses a chemical into it containing its DNA. Once inside, the DNA duplicates over and over making copies of that virus until the cell explodes releasing the new virus' and they repeat the process. You cannot kill a virus with medicine since it is not a living thing. Bacteria on the other hand is a living thing.
once you die, they find out in thw autopsy
HIV is a virus, and can't be removed from the body once infected.
i dont really no
