PrEP may prevent HIV infection even when not used daily

The medication used to prevent HIV infection, Pre-exposure prophylaxis (or PrEP), can now be taken as needed rather than daily, according to a new study. Researchers found that on-demand use reduced risk of HIV infection by 97 percent. The team also noted that while using the medication, more people opted not to use a condom, rising from 77 percent at the baseline to 86 percent.
