England’s PrEP Impact Trial ran between 2017 and 2020. This chapter centres first on the policy events that first gave rise to the trial underpinned the trial’s genesis. Interviews with key stakeholders demonstrate that rather than achieving its aims as practical implementation trial that might have enabled and shared learning on the best ways to roll out PrEP, instead the Impact trial was designed and maintained as a ‘show trial’ to help manage a policy and financial impasse. Those interviewed tended to observe that because Impact’s power dynamics were rooted in traditional hierarchies about the production of evidence, this undermined its use as anything more than a stop-gap. Ultimately, rather than enabling the sharing of lessons for those planning the immanent launch of England’s future PrEP services, this trial’s legacy will instead be largely about the divisions and inequalities that it has exacerbated.
