Recently we got great news from a real-world study of HIV pre-exposure prophylaxis (PrEP).

Researchers at San Francisco's Kaiser Permanente Medical Center reported on the real-world experience of 657 people who started PrEP between 2012 and 2015. Over 99% were men who have sex with men, 84% reported multiple sexual partners, and 30% had HIV-positive partners. Together they were observed for over 388 person-years of PrEP use.

The big news: Exactly zero patients contracted HIV infection! That's huge.

The problem is, the popular conversation about it has been over the top. From The Washington Post to FoxNews and the Huffington Post, people have been saying it's "100% effective" and lots of other undeserved superlatives.

PrEP works, this study was great, but there is real danger in all of this over-hype.
