That's been in the works for a while. Sad HIV got politicized as being a "gay disease" so that many refused to do anything about it because that might help someone else, but piss and moaning aside, it's nice to see some progress from time to time.
Somewhat related, a friend of mine was part of the group used to test the HEP-C cure. He'd gotten hep through a transfusion and labored with it for years, was nice to know he'd gotten to where it wasn't under control, no remission, but actually cured.
I wish we had more support for science and medicine to try and solve more of the ails of the world; imagine what we could accomplish.
