A study shows that a twice-yearly shot was 100% effective in preventing new HIV infections in women in Africa.

Twice-yearly shots used to treat AIDS were 100% effective in preventing new infections in women, according to study results published Wednesday.

There were no infections in the young women and girls that got the shots in a study of about 5,000 in South Africa and Uganda, researchers reported. In a group given daily prevention pills, roughly 2% ended up catching HIV from infected sex partners.

“To see this level of protection is stunning,” said Salim Abdool Karim of the injections. He is director of an AIDS research center in Durban, South Africa, who was not part of the research.

The results in women were published Wednesday in the New England Journal of Medicine and discussed at an AIDS conference in Munich. Gilead paid for the study and some of the researchers are company employees. Because of the surprisingly encouraging results, the study was stopped early and all participants were offered the shots, also known as lenacapavir.

        AIDS has been the most dangerous STD for decades. It has changed attitudes to sex worldwide. Having a vaccine is going to change them again.

          There’s already very effective medicine available in the west to treat and prevent HIV/AIDS, we call it PrEP.

            This is more effective than prep and easier, because you only need a shot every 6 months. The testing for this new shit involved using prep for the control group.

            The new medicine worked so well they stopped the trial and gave the control group the shot. No one with the shot got sick at all. If they had continued with the control group, a few of them would have gotten AIDS.

        Not to sell out my community but I know quite a few people whose condom use went down after they got on PrEP
