Question

How does HIV leads to AIDS? Is there an HIV vaccine? How can you avoid HIV infection?​

Answer 1

Explanation:

HIV destroys CD4 T cells — white blood cells that play a large role in helping your body fight disease. The fewer CD4 T cells you have, the weaker your immune system becomes. You can have an HIV infection, with few or no symptoms, for years before it turns into AIDS.

There is currently no licensed HIV vaccine on the market, but multiple research projects are trying to find an effective vaccine.
