What We Said After Step in 2007* *...and after RV144 in 2009; 505 and Phambili in 2013 R&D is an iterative process Every trial teaches us something We need a wider variety of approaches in the pipeline Vaccines take a long time to develop Samples from the trial are a precious resource to help explain what happened with the vaccine The field must take a deep breath, a step back and assess the implications Proceed with discovery work that includes human clinical trials
5
What’s Past is Prologue Large efficacy trials are possible and essential – and complex and unpredictable It’s not the result as much as what we do with it o No matter what the headlines say, a single number is not the full result No one trial answers all the questions o Just as no one product or approach is “the” answer for AIDS vaccines o Just as an AIDS vaccine is not “the” answer to ending the epidemic It’s all incremental – no magic bullets
6
Where to from here Mine trial data in every way possible, using the limited trial samples strategically and wisely Continue the upstream scientific focus to develop better candidates that can build on current knowledge, fill gaps and get into trials Think harder about new trial designs Deliver what we have today for prevention & treatment

AIDS Vaccines 2013 and beyond P5 – Pox-Protein Public-Private Partnership Other products currently in clinical development Replicating vectors Translating NAb discoveries into vaccine candidates Passive immunization and gene therapy studies And how to engage a variety of communities and stakeholders in the inevitable ups and downs and uncertainties
8
What is “stakeholder engagement?” Stakeholder engagement is not recruitment! (Recruitment is recruitment…) It is a process of using the expertise stakeholders have to improve the research process and shape it together It requires/benefits from improved research literacy amongst all stakeholders Good Participatory Practice Guidelines for Biomedical HIV Prevention Trials, UNAIDS & AVAC, 2011, www.avac.org/gpp.
9
Now what? Ensure preparedness efforts for “P5” trials are on track in Southern Africa and Thailand o Stakeholder dialogues; ongoing coordination with P5 partners; GPP work at proposed site levels o Publications and communications that address “what next”, “why so long” and clarity of changing timelines Work to consensus on appropriate standard of care and prevention in proposed trials including P5, passive immunization trials and others Sharpen and sustain messages about need for continued funding, state of the science and pipeline, and essential role of vaccine in long-term success at “ending AIDS” Connect preventive vaccine agenda and advocacy with o Broader “ending AIDS” advocacy o Therapeutic vaccine and cure agendas and advocacy
