Is it confirmed yet?
It's quite impossible to destroy the HIV microbe and the chances are low its a definite cure for it. They will probably test it on some 'volunteers' to see its effects first as usual, then sell it to pharmaceutical companies and maybe it will be distributed to Ministries of Health for a quite high price. So don't expect free healthcare is for these kind of things. Free healthcare is for check-ups and antidotes against colds, flus and sirups. Not for HIV cure.
What will happen, if it is indeed a cure?
Massive protests all around the world against governments and pharmaceutical companies as usual for not distributing it freely with healthcare cover. It already happened when there was a lawsuit against South Africa about blocking affordable drugs to fight AIDS in Africa. It will happen again and as usual the pharmaceutical company sharks will profit from our illnesses by selling the drugs in impossible to afford prices.
