The setting is 1980s USA, Nevada in particular. The world is your typical urban fantasy world-- that is, completely identical to this world save the addition of fun things like magic. The magic is a secret, though, if that makes any difference.
I've got a character born in 1966. He gets his learner's permit in 1983 at age 16 and within a few months gets in a car accident. He loses a lot of blood and consequently has to have a transfusion. I've got him being exposed to HIV via this transfusion, then by 1985 or 86 he gets pneumocystis pneumonia, is hospitalized, and is diagnosed with AIDS. Shortly after that-- a year, give or take a few months, so in 86 or early 87-- he's turned into a vampire in an effort to cure him, rendering the disease no longer fatal since by that point he's technically dead.
I know that screening blood for HIV started in 1985, so I want him to have gotten it before there were conclusive tests to be done on donor blood. I also know that AZT was invented in 1987, but I want him and his father to think that the only way to keep him from succumbing to the disease is by turning him into a vampire. Choosing living forever over a shortened life, essentially.
Now, do I have the basic timeline right? Wikipedia says that infection to the latency stage can take around two months, and the latency stage can last as long as twenty years and as short as two weeks. Is the two or three years given in my timeline realistic enough?
