HIV is a virus that evolves so rapidly that it is difficult to keep pace with the vaccines that could help avoid the disease.
Unfortunately due to this evolving mutation within the body there is still no effective way to prevent the contraction of HIV.
The HIV infection reacts differently according to various body types, some people may develop symptoms of AIDS after just twelve months, while amongst others it will take ten or even twenty years for the disease to breakout.
The HIV infection progresses according to the number of HLAs (human leucocyte antigens) each one of us has, and every single person has a different number of HLAs, this will determine how long it takes for AIDS to develop after an infection.
The HLA gene was studied in different countries to examine the way HIV infection reacted to the different kinds of genes.
Researchers found that the HIV infection evolved extremely rapidly in those populations with a high frequency of a specific gene.
These results showed that the HIV infection adapted best in those populations that contained the virus most successfully, thus demonstrating that the HIV virus evolves at an extremely rapid pace.
This does not necessarily mean that it cannot be controlled; it may also prove that the immune system is responding more effectively. Once an effective vaccine is found, it must be adapted as fast as the HIV infection to keep the pace with the latter’s evolution.
Before any vaccine can be found, more research is needed and it may still take years before a solution is discovered, but scientists are keeping up with the HIV’s mutation and studying the prospect of a vaccine as a great step towards conquering the virus.
