A pill to prevent HIV transmission appears to be effective, according to two recent studies. Of 657 test subjects in San Francisco, none were infected with HIV. In the UK, test subjects showed a lower risk of being infected. A number of test subjects did contract other sexually transmitted infections, however.
According to Newsweek, “The study can’t say whether the high rate of STIs is due to PrEP use. STI diagnoses may have gone up because patients on PrEP tend to make more doctors’ visits, allowing more opportunities for infections to be found.”
