To say we're big fans of Disney movies is an understatement—Ariel sang at Greatist's fifth birthday, after all. So when Todrick Hall's latest video, inspired by The Lion King, popped up in our feed, we clicked without even thinking. Turns out, "Hakuna Truvada" (a play on "Hakuna Matata") is both catchy and informational. The song teaches listeners about Truvada, a pill taken daily to reduce the risk of HIV infection. The drug, which is often referred to as PrEP, a shorthand version of the scientific term preexposure prophylaxis, requires a prescription, so it's something to talk about with your doctor if you're part of a high-risk group for contracting HIV.
