Correct me if am wrong, the world has united in the past against whooping cough, small pox, measles...why not against AIDS or cancer or malaria?

Furthermore, even if you had cures for all known causes today, people would still die from new causes, and from these, pharms would make lots of patent money.

From this perspective, pharms are not in danger of profit erosion from such advances

Cures for these two conditions will always be availed as alternative medicine, with a lot of propaganda from the pharma/government agencies on how ineffective they are.

The problem is that we are fragmented and nobody knows what the other person is doing unless you meet at an international conference to present results.

I & others are deeply involved trying to profile the prevalence of which coreceptor (R5 and X4) the viruses are using to enter the cell. Development of resistance against all the virus targets is very easy.... skip medication or the virus mutates under drug pressure BUT human genome will not be pressured by the virus to mutate.
Remember in a patient, HIV is not clonal but exists as a quasi species. If only CCR5 exist then the patient can benefit but if CXCR4 then the patient is excluded. Also remember that all the other HIV therapies target the virus but this one targets the host (patient).
