AVAC Report 2019: With 2020 targets sure to be missed, we ask Now What?

Report cover

Today, AVAC released Now What?, our 2019 annual report on the state of the HIV prevention field. Each year, the AVAC Report frames the most pressing advocacy issues facing the HIV response. At the threshold of 2020, it’s clear that global goals for HIV prevention will miss the mark by a long shot.

Though important progress has been made, the crisis UNAIDS called out in 2016 persists today with new infections around 1.7 million annually, a far cry from the 2020 target of fewer than 500,000.

So, we asked ourselves, Now What?, and answered with cross-cutting analysis and an advocacy agenda to match.

FIRST, we call for leadership that is bold, visible and activist, from the new head of UNAIDS, to houses of parliament to civil society coalitions: take uncompromising stances, demand accountability, speak out for intersectional issues of race, gender, class and climate. This work needs to be funded, full-throttle and fearless.

SECOND, we call for the use of today’s most recent evidence to guide new prevention targets that will pave the way for epidemic control. Clear milestones for the prevention research pipeline must be set. Investments over the past decades have provided us with the prevention options we have today, and much-needed new strategies are under now investigation. The field needs targets for prevention research that people can understand and influence.

THIRD, we call for multilayered prevention approaches that are centered around the person, not the virus. Since last World AIDS Day, we’ve learned again, perhaps most strikingly from the ECHO trial, about the dynamic needs of women for HIV and pregnancy prevention. The complexity of translating results into policy, bring renewed urgency to the need for comprehensive HIV prevention and reproductive health approaches. Multilayered prevention incorporates multipurpose strategies (i.e., products that prevent both pregnancy and HIV) within programs designed to address structural barriers (i.e., policy reform, transforming community norms, facilitating educational empowerment).

2020 will be a pivotal year—join us in calling on leaders, from the grassroots to global capitals, to make 2020 a turning point, when siloes come down, crises are transformed by innovation, and prevention is center stage in the fight against HIV.

Happy reading, and we’d love to hear how you answer Now What?

AVAC’s “3D” View of the World: 2019 and beyond

This infographic lays out AVAC’s top-line recommendations from AVAC Report 2019: Now What? The recommendations fall into three categories: deliver — prevention programs whose impact is well-measured and -defined; demonstrate — next-generation engagement for next-generation trials; develop — new targets for the post-2020 world.

HVAD 2019: Vaccine science needs your support!

[UPDATE: Slides and recordings from both webinars are now available. Links are provided below.]

HIV Vaccine Awareness Day (HVAD) 2019, on May 18, comes with promising headlines about advances in potential vaccines for HIV and other diseases that imperil public health. But, 2019 has also seen outbreaks of a highly infectious, vaccine-preventable disease, the result of misinformation and fear being spread by anti-vaccine campaigners.

This HVAD, AVAC has an updated toolkit of resources for translating HIV vaccine research with a renewed sense of urgency, and two dedicated hashtags to rally the call on social media: #HIVvaccineAware and #HVAD2019. We hope you’ll join the conversation — with the updated HVAD 2019 toolkit and our upcoming webinars (below and online)!

We also hope you will join two upcoming webinars:

Resources like these are essential for public understanding and support for vaccine research. Vaccines are not simple products. They require sustained investment to develop, they can be challenging to manufacture, and just as challenging to explain to potential users.

This HVAD, join us in thanking the ongoing dedication and ingenuity – of scientists, trial participants and community advocates – to find a vaccine against HIV, and let us renew our commitment to advance public understanding and support for vaccine research, development and delivery.

HIV-Specific Neutralizing Antibodies – Targets and research status

Numerous studies, both early and late phase, are investigating the efficacy of neutralizing antibodies. This infographic shows the ongoing studies and the differing locations they target on the virus.

One Timeline, Two Stories, One Message: Putting trials and targets together

One problem with HIV prevention agendas is that they either live in an eternal present or in a far-off future. It’s “work with what we’ve got, which is condoms and VMMC and a little bit of PrEP”, or it’s “nothing can change without an AIDS vaccine”. The future depends on using what’s available, better and more widely, without ever losing sight of what’s in the pipeline.

As the figures below show, in the very same timeframe that the world will miss its critical target for incidence reduction and scale-up of primary prevention, several trials will release results that could change the future. 2020 will be a time of hope and reckoning. But only if the two stories start to be told as one.

HIV Prevention Research and Demonstration Sites in South Africa

This map demonstrates the breadth of HIV prevention research and demonstration projects in South Africa by site and type (e.g. daily oral PrEP demo projects, ARV-based rings, long-acting injectable PrEP, preventative Vaccines, antibodies, hormonal contraceptives). This map was developed by Wits RHI with support from AVAC as part of the Coalition to Accelerate and Support Prevention Research. This graphic first appeared in AVAC Report 2017: Mixed messages and how to untangle them.

No Prevention, No End – AVAC launches new report and call to action

Today AVAC released No Prevention, No End, our 2018 annual report on the state of the field. Starting from the title—which humbly borrows the cadence of the call for an end to state-sanctioned violence against Black Americans, “No Justice, No Peace”—through to the closing words, “This is the worst possible moment for slowing down,” the Report is a call to action and guide for addressing the HIV prevention crisis that threatens progress in curtailing epidemics worldwide.

Click here to download the Report and individual sections and graphics; click here for a new episode of the Px Pulse podcast which covers the Report’s key themes and features lead author Emily Bass, AVAC’s Director of Strategy and Content.

UNAIDS named the prevention crisis in its July 2018 report, Miles to Go. It acknowledged that the scale-up of antiretroviral treatment, while essential, is insufficient as a prevention strategy. AVAC has been warning of an imbalance in approaches and investments across approaches, and calling for ambitious targets matched with political will, financing, timelines and more since the UNAIDS targets were first launched in 2014. (Check out AVAC Report 2014/5: Prevention on the Line for a summary of this critique of targets.)

In this year’s Report, we call out three core problems with primary prevention and the global HIV response, identifying the risks they bring and the path to a solution. Specifically, we focus on:

  • Investing in demand creation: The private-sector gloss on this term cannot obscure its essential role in making primary prevention work. Strategies that might save lives are condemned as unwanted or unfeasible when they’re delivered in programs that lack integrated demand-side thinking, which is a science and not a set of slogans.
  • Making informed choice central to HIV prevention: Programs that offer more than one option, along with a supportive environment for a provider and client to discuss risks, benefits and personal preferences aren’t a luxury but a necessity. The family planning field has metrics to measure choice; HIV should pick these up, with prevention programs leading the way.
  • Unstinting radical action: Progress in the global AIDS response is tenuous; so is the state of democratic institutions and the future of the planet. These interconnected issues require more bold action, including from countries that are aid beneficiaries, and from the citizens of those countries who unite to hold truth to power. In the HIV prevention context, this means accountability for primary prevention at every level, including research for next-generation options.

AVAC is launching this Report as many stakeholders in HIV prevention research gather in Madrid for the HIV Research for Prevention (R4P) conference. Visit our special R4P page to find us on-site and follow along from afar, to see how the themes of this year’s Report resonate in a global and wide-ranging discussion of HIV prevention research and implementation at a critical time.

HIV Vaccine Awareness Day 2018: Tools & more

HIV Vaccine Awareness Day, May 18, commemorates the vital and ongoing work to develop a vaccine against HIV. This work advances because of the ingenuity, courage and commitment of trial participants, host communities, funders, scientists and advocates. AVAC salutes the collective trust and sustained dedication to end the epidemic.

2018 is marked by great advances in research and important opportunities for advocacy. In addition to a host of tools AVAC updates annually to keep you current on this front, The Rise of Broadly Neutralizing Antibodies by AVAC founder and former Global HIV Vaccine Enterprise executive director Bill Snow offers a comprehensive look at antibody mediated prevention and its connection to vaccine research.

In case you missed it, check out the recording and slides from the May 17 webinar featuring Dr. Sandhya Vasan’s discussion on the legacy of RV144 and vaccine advocate Mark Hubbard’s take on today’s agenda for HIV vaccine advocacy.

The Rise of Broadly Neutralizing Antibodies

Bill Snow founded AVAC and is the former Global HIV Vaccine Enterprise Executive Director.

Research on broadly neutralizing antibodies (bNAbs) is taking the field of HIV prevention science in new directions, with implications for new prevention interventions and vaccine development. There’s much to know and much to learn about these powerful instruments of the immune system.

Since 2016, more than 2,700 men in Brazil, Peru, Switzerland and the US, and 1,900 women in Southern Africa have begun to enroll in clinical trials looking at antibody-mediated prevention, or AMP (see Figure 1). A collaboration between the HIV Prevention Trials Network (HPTN) and HIV Vaccine Trials Network (HVTN) (both funded by the National Institutes of Health), the AMP studies test the safety and efficacy of the broadly neutralizing antibody (bNAb) VRC01 when it is given every 8 weeks to reduce the risk of HIV infection. But how did this approach come about, why is it important and what may happen next with bNAbs for HIV prevention?

What’s an antibody?

Antibodies are Y-shaped proteins produced by B cells to clear infected cells and pathogens in the bloodstream. B cells are part of what is known as the adaptive immune system, which mounts defenses aimed at specific invaders—like a cold virus or chicken pox or HIV. The innate immune system also defends against invaders, but its defenses are not so finely tailored to a specific pathogen. When a virus encounters the right B cell, the B cell begins cloning itself and produces antibodies designed to battle that virus. These antibodies circulate throughout the body looking for the virus, and they evolve continuously, becoming ever more precise and numerous.

The Antibody Hierarchy

Here are some terms that will help you follow this ongoing story:

  • Antibody: Proteins produced by B cells as a major part of the adaptive human immune defense against specific invaders.
  • Binding antibody: An antibody that attaches to a virus but doesn’t necessarily render it ineffective; can be driven by the innate immune system.
  • Monoclonal antibody: A bioengineered antibody made in a manufacturing facility by copying (cloning) one original antibody—selected for its potency and other characteristics.
  • Neutralizing antibody: Antibody that disables virus.
  • Broadly neutralizing antibody: An antibody that neutralizes many different genetic variants of HIV.
  • Passive antibodies: A dose of monoclonal antibodies that are infused or injected, rather than made by one’s own immune system.
