AIDS, RESEARCH Research into an AIDS virus vaccine. Illustration of the creation of a virus enabling the production of GP120 and GP41 molecules (the AIDS virus' harpoon molecules which allow it to latch onto the cells it infects) by a vaccinated monkey's own organism. While the GP120 molecules mutate during virus duplication, the GP41 molecules do not seem to. This triggers an immune response making it possible to obtain GP41 antibodies and memory T lymphocytes. This vaccine is obtained using fragments of AIDS DNA along with measles DNA.
