When developing a new vaccine the researchers will need to find out which receptors play a role in the spread of a virus or bacteria, and look at the molecular shape.
Vaccines contain bacteria or viruses (microbes) either parts of wholes that have been killed or weakened so they don't causes diseases. These microbes work with the immune system to create antibodies against the bacteria or viruses. So if you are exposed say to Measles the body remembers these bacterias or viruses so the body is able to fight of the diseases quickly and you don't get sick.
One challenge scientists must overcome in developing an AIDS vaccine is the high genetic diversity of HIV, which makes it difficult to create a single vaccine that can protect against all strains. Additionally, the ability of HIV to rapidly mutate and evolve also poses a hurdle in vaccine development.

Vaccine
You don't, at least in America. Rabies vaccine must, by law, be administered by a registered vet.
A number must always be followed by it's correct unit.

I am afraid the answer below is wrong, as researchers have managed to make one to the core proteins that don't change between strains. I was just wondering why it hadn't been done earlier. (quote of Wrong answer) There is no universal flu vaccine. It must be reformulated each year to try to match the flu strains though likely to be most important in the coming flu season. (end quote of wrong answer) The fact that a universal flu has not been made earlier (though as of October 2008 is not commercially available) likely has to do with funding issues, changing technologies and the requirement for studies and clinical trials. Since Type A flu mutates more readily than Type B, the research is aimed at finding and utilizing aspects flu viruses that do not readily mutate. So the mechanisms that would make it work are not the normal killed-virus vaccine. They must go through a process of studies and clinical trials before they will be approved by FDA. Fear of the Avian flu has spurred the research. See Related Links for more information.

Rabies shots should be given in deltoids or triceps muscle. Vaccine must never be given in hip region. You may give the vaccine in fatty tissue, making it useless. Alternately the vaccine may be given, as intra-dermal injections, as about 8 doses of 0.1 ml, on day zero, to achieve rapid increase in antibody titre.
Vaccines administered intravenously are CONTRAINDICATED! In order for a vaccine to work, the antibodies or the weak viruses must be given time to multiply. This can only be done when the vaccine is administered intramuscularly or subcutaneously, the latter being the most common route.
