For information about other recruiting clinics, please see the IMPACT trial website. If you would like to discuss other ways to access PrEP, please book an appointment at our Guys@Marys clinic. We still have limited places for other people who are at higher risk of HIV. If you would like to find out about joining the trial, please walk in to speak to one of the team.
