The article discusses the prevention of HIV, including the use of PrEP (Pre-Exposure Prophylaxis) and PEP (Post-Exposure Prophylaxis). PrEP is a daily medication that can prevent HIV infection, while PEP is a course of antiretrovirals taken after exposure to HIV. A new form of injectable PrEP is being developed, which would only need to be administered every six months. This new form of PrEP could provide an alternative for individuals who have difficulty taking daily medication.
