Francoise Barre-Sinoussi the woman who co-discovered HIV in 1983, and won a Nobel Prize for her work,French scientist said in International AIDS Society Conference, in Vancouver,the future of HIV is gloomy and why there's still no cure.
Hiv virus cannot be prevented by any vaccine as yet as we do not have a vaccine, I think we have learned a lot from the negative results as well ... it's not a failure. We are learning from negative data as much as we learn from positive data and I think vaccine research is typical of that. In the last six - seven years we are starting to see a lot of progress in the field of HIV vaccine.I think the field of vaccinology in general is moving and maybe I am too optimistic, but I like to think because of HIV the field of vaccinology globally is moving, not only for HIV.
But difficult to say today, because we do not have a cure. I am not sure, by the way, we will have a cure. I used to say to develop a cure for HIV is an impossible mission because the reservoir of cells is not only in the blood. How to eliminate all the cells which are reservoirs is why I say it's an impossible mission. They are everywhere -- in the gut, in the brain, in all the lymphoid tissue.Even if you have a very efficient strategy, how you can make sure that there's not one or two cells still there and if one is there the virus will reappear again? That's why I say it's an impossible mission.
So BOTH CURE AND VACCINE NEEDED FOR ITS COMPLETE CURE OR ERADICATION UNTIL THEN ONCE DISEASE LIFE LONG HIV ARV OR HAART MEDICINES ARE QUITE EFFECTIVE FOR PATIENTS AS WELL AS PROTECT THE NEAR ONES AS CONTACT AND HEALTH PERSONEL BY BOTH PRE AND POST EXPOSURE PROPHYLAXSIS WHICH IS QUITE EFFECTIVE TO PREVENT DISEASE AND MAKE LIFE FULL OF QUALITY AND QUANTUM FOR PATIENTS.
