Press Release

The Search for an HIV Vaccine Must Continue

Field Will Learn for Halted PrEPVacc Arm

New York, 6 December 2023 – Today the PrEPVacc trial team announced at a special session at the International Conference on AIDS and STIs in Africa (ICASA) in Harare, Zimbabwe, that they were stopping vaccinations in the study following a review by an independent data safety committee that determined there was little chance the vaccines being tested could stop HIV acquisition. The oral PrEP arms of the study will continue. 

PrEPVacc was testing two different vaccine strategies against a placebo: one regimen combining a DNA vaccine with a protein-based vaccine (AIDSVAX), and another regimen combining DNA, MVA and a protein-based vaccine (CN54gp140). 

“We always hope for a positive outcome in HIV prevention trials, and this news is disappointing,” said Mitchell Warren, AVAC executive director. “We look forward to seeing the full PrEPVacc data in 2024 and hope it will add to the body of evidence that is helping scientists understand how to develop better vaccine candidates that will one day protect against HIV.”  

“The PrEPVacc outcome underscores yet again that the science of HIV vaccine development is extremely challenging,” he added. “Now is not the time to step back from vaccine research. There are several promising strategies in early-stage research that must continue, along with research for other HIV prevention options. We will not end HIV without ensuring that everyone who is vulnerable to HIV infection has a choice of effective and desirable prevention options.”  

Importantly, PrEPVacc’s PrEP arms will continue. The study is testing two different formulations of daily oral PrEP, looking to see if a new formulation – F/TAF (also known as Descovy) – is at least as good in the trial population at protecting against HIV acquisition as F/TDF (also known as Truvada and the most widely used version of PrEP). The trial will provide the first data for F/TAF among cisgender women (who make up 87% of the just over 1,500 PrEPVacc trial participants). F/TAF is approved for use in the US and UK, but not for those individuals who have receptive vaginal sex, since previous trials regrettably did not enroll cisgender women. 

The PrEPVacc study is scheduled to conclude in 2024 and data from all arms of the study are expected to be reported in the last half of 2024. 

“The PrEP arms of PrEPVacc will provide important insights into the potential of expanding access of F/TAF for PrEP to women in East and Southern Africa who need additional options to protect themselves from HIV. Equitable access to new interventions should be a goal of every research program,” said Stacey Hannah, AVAC’s director of Research Engagement. 

“PrEPVacc is a complex, innovative trial design, and, while the vaccine result today is disappointing, the trial team has worked from the outset to implement the Good Participatory Practice (GPP) Guidelines. The team’s hard work on the front-end to apply GPP to this trial is paying off especially now in the ability to deliver complex, disappointing results to trial participants, advocates, policymakers and other key supporters of PrEPVacc and of HIV prevention broadly.”

AVAC Commemorates World AIDS Day

This World AIDS Day we at AVAC are reflecting on remarkable gains and increasing threats to progress against AIDS. Our latest issue of PxWire, tracking trends in research, development and delivery of HIV prevention options, speaks to this important progress: 

However, as we look to 2024, all these gains could be imperiled by political and financial choices facing leaders today.

The answers to these questions will require donors and political leaders to do the right thing, and it will depend on us, a global movement of advocates with a track record of world-changing achievements, to stay the course and build the road to reach everyone one of these goals. Below are a few key resources to support your work.

At AVAC, we believe it’s up to all of us to make sure the world does not squander another decade in slow, fragmented rollout of life-saving innovation in HIV prevention or risk underfunding research and development. If we work together to build equity into the rollout of options that exist already and support the promise of expanding choices in the near future, the world will at long last bend the curve of HIV.  

Call to Action for Voluntary Medical Male Circumcision

The Job Is Not Done Yet

In the pursuit of a future without HIV and AIDS, voluntary medical male circumcision (VMMC) remains an integral component of the arsenal in HIV prevention, offering a cost-effective and scientifically proven intervention that holds immense potential in curbing the acquisition of HIV.

Spotlight on New PrEP Tools and Data: From R&D to access

Tuesday, November 28

Between the recent accelerated growth in global PrEP initiations, and the introduction of new PrEP products like cabotegravir and the dapivirine vaginal ring, the field of PrEP data has never been more exciting or more complex. Staying on top of the latest advances is key for advocates, researchers, funders, and others working in HIV prevention to do their job effectively—but how can you navigate the vast amount of PrEP data online? AVAC, the Medicines Patent Pool (MPP), and Unitaid presented information on three important online PrEP resources and understand how they can support and enhance your work:

  • PrEPWatch.org: the one stop shop for PrEP resources to support introduction and scale-up, including the PrEPTracker, the only place to find information on global PrEP initiations online
  • Long Acting Therapeutics Patents and Licenses Database (LAPaL): LAPaL is the go-to resource to learn about long-acting therapeutics, their patent landscape, development and regulatory status
  • Access to Medicines Tracker: the go-to place for quarterly-updated insights on regulatory filings, regulatory approvals, and product supplies of MPP-licensed generic medicines at the country level.

Getting the COVID-19 Vaccines We Need

As of March 2023, the World Health Organization reported that there are 199 COVID-19 vaccines in pre-clinical development, and 183 in clinical trials. Most are injectable; but 16 candidates are intranasal, 5 are oral, 2 are inhalable, and 1 is an aerosol.

HIV Vaccine Research

HIV vaccine research is a multifaceted endeavor that requires collaboration across many disciplines to develop a vaccine that protects people from HIV infection. The graphic outlines the different areas of research that are being pursued, including vaccine platforms, immune system research, clinical research capacity, and community engagement.
