FDA approves first monthly injectable to treat HIV infection

Great news. There are definitely a number of people out there who, in part due to social circumstances have difficulty taking meds daily and this will likely help a good proportion of them.

I have always heard that Truvada (prep) was extremely effective at preventing HIV infection. These new injectables are reported by the article to be 89% and 66% more effective at preventing transmission.

What is this based on? Was I misinformed about Truvada's effectiveness? Is this a decrease in an already very low chance of transmission? Or is this in comparison to people forgetting to take their daily pills vs a shot that a health care provider had record of administering?

It's currently common in the gay community for sexually active, healthy people to take Truvada proactively to protect against HIV because it's understood to be even more effective than condoms. If there is a better option or if the current option is not as effective as widely believed then standard of care should change.

> Was I misinformed about Truvada's effectiveness?

No, effectively used Truvada works very well.

Probably almost certainly yes or it's just a small improvement at the margin.
