While there are still 85 sites at which the PrEP trial is available, these are not evenly distributed geographically. Some of the most popular sexual health clinics with the LGBT community, such as London’s Dean Street, filled their trial quota in just weeks.ĭr Alan McOwan of Dean Street told PinkNews: “We had a capped allocation that was used up very quickly… it’s very frustrating to have to turn people at high risk away.” 26 locations involved in the trial have closed recruitment so far, according to data made public by the IMPACT trial.
