Answer 1

Your link worked for me. This drug works by closing the pores that the virus uses to enter the cells. Since it acts on human cells and not the virus, the virus can't mutate to be immune to the drug. I hope this one turns out to be good.

Answer 2

Your link goes nowhere, unfortunately.

I'm having trouble finding useful information about the the drug Isenstress. Apparently, it blocks the insertion of HIV genetic material into human DNA and in doing so prevents replication of the virus but I don't know the mechanics of this. I would venture to say that this is a possible key to preventing all viruses that taking up residence. I would also venture to say that in the past, the approach to defeating HIV was quite different and involved a direct attack on the virus itself. Merck has devised an indirect attack and is actually a defense rather than an offense. Therefore, that is probably why it works when nothing else has.
