What should be kept in mind is that the deaths are a result of a run away immune response.
While a virus will not be available for some time and hopefully shorter a anti viral. In the meantime drugs that protect the patient from their own immune system will buy time.
There are two drugs I have read about that are in phase three with good results in previous testing. The drug company is not releasing details other than that that was revealed to go to phase three.
As for;
HIV is curable (remission) but no vaccine. So much so that HIV drugs are now openly advertised on TV. Also they have a drug (percep spg) that if taken prevents infection.
AIDS is no longer classified as terminal (developed countries) now a chronic condition.
