Haven't read it but I'm pretty certain no one will be getting injected with HIV, lol. Once they're happy with the safety of it, I'd imagine they will take from a selection of people who currently don't have HIV but are in an at-risk group, e.g. couples with one HIV-positive partner, promiscuous bummers like Matt Canning and Primemuscle; fat, gay Black men like Goodrum, etc.
