AIDS: Decades of research but still no vaccine

Even with no sudden increase of HIV, there are still some 50 million AIDS patients worldwide, of which a few millions die annually

Unfortunately, there isn't any vaccine yet since the mid-1980's.

Come to think of it, even if there is a vaccine, it would not be a life-long immunity, like what is happening with all the multiple Covid vaccines now..

Why would this be the case? other retroviruses like the HTLV-I and HTLV-II, can be controlled by the immune response and most of the people that are infected never develop disease. A vaccine could lead to the same for HIV, the infection remaining controlled and virus titers in blood low or undetectable for the life time of the person (with the risk of disease if the person become immunocompromised by other reasons).

People with HIV can now live a regular life if they can get the medication required to help control the virus. The article states the major reason it takes decades for vaccines to be brought to market....in non-pandemic times.....money and the political will for relentless research. This is one of the main reasons that the covid vaccine was brought out so soon and the other was decades of research into other coronaviruses and how the mRNA vaccine technology works against them. HIV research had to begin from the very bottom. There is a prophylaxis treatment available that is highly effective at protecting people from HIV....PrEP...Pre-Exposure Prophylaxis is around 98-99% effective in preventing infection through sex when taken properly
