Breakthroughs Blog: Vaccines

In this guest post, Jamie Rosen—media and communications manager at Aeras—writes about a new film series that features personal stories of people affected by tuberculosis (TB) worldwide, and the urgent need to develop new vaccines and other tools against the disease. Aeras is excited to share the trailer for a series of short films exposing the underreported global epidemic of TB and the movement for innovation to improve our tools to fight it. In the TB community, as in other areas of global health, we are constantly seeking ways to help people comprehend the scale and the individual tragedy of this disease, to understand the difficulties of treating it, and to inspire people to do what it takes to adequately address it. Aeras has been working with filmmaker Mo Scarpelli and her crew over the past several months to produce four films. Each film will focus on the story of one individual interspersed with expert interviews, and will feature footage from five countries around the world. The first film will focus on an American multi-drug resistant TB survivor; the second on an Indian TB doctor; the third on a South African woman who volunteered for a clinical trial; and the fourth on a British researcher working to develop new TB vaccines. Aeras is grateful for the advice and participation of many people who are working tirelessly to take care of today’s TB patients and foster hope for a better future—one with more effective diagnostics, drugs and ultimately vaccines against this rapidly evolving disease.

In this regular feature on Breakthroughs, we highlight some of the most interesting reads in global health research from the past week. Cipla and the Drugs for Neglected Diseases initiative recently announced that their malaria drug has been prequalified by the World Health Organization, an important step toward its roll-out across Asia. A new report from the Kaiser Family Foundation provides a comprehensive look at the Department of Defense's role in global health, including the department’s research and product development efforts. The US Food and Drug Administration has awarded GHTC member Aeras a grant worth $299,525 to spur the development of new vaccines against tuberculosis. A new study finds that the way medical research is funded in the United States has been vastly altered over the last 20 years by advocates asking that research be focused on particular diseases. A widespread vaccination campaign to protect 50 million people against meningitis with a new vaccine has been launched in seven African countries, health officials said Thursday.

In this guest post, Margaret McGlynn, president & CEO of the International AIDS Vaccine Initiative (IAVI), writes about a new partnership between IAVI and the Indian government. The post originally appeared on the US Agency for International Development’s (USAID) Impact blog. When you’re dealing with a global public health crisis, having an international presence isn’t just advisable—it is imperative. This applies as much to the development of new tools to prevent disease as it does to treatment. An AIDS vaccine candidate, for example, must be tested in the people who will eventually use it and against the strains of HIV it is devised to protect them from. That’s why (IAVI), in partnership with USAID, has worked diligently over the past several years to establish itself as a truly global nonprofit partner. Using donor funds, IAVI has created an enviable network of research centers in sub-Saharan Africa dedicated to assessing novel AIDS vaccine candidates in clinical trials and conducting supporting epidemiological studies on HIV. These partnerships have made meaningful contributions to the research capacity of many developing countries—a capability that is now helping local researchers tackle other diseases. IAVI and its partners are now applying that same model to support the design of a new generation of AIDS vaccine candidates. Today, IAVI and the Translational Health Sciences and Technology Institute (THSTI), an autonomous institute of the Indian government’s Department of Biotechnology (DBT), launched an HIV Vaccine Design Program near New Delhi. The program is dedicated to the large-scale generation and preclinical evaluation of immunogens, the active ingredients of vaccines. It will focus on devising immunogens capable of eliciting antibodies that can prevent infection by a broad range of the circulating genetic variants of HIV. That challenge, known to researchers as the neutralizing antibody problem, has long stymied progress toward an AIDS vaccine. But recent discoveries of antibodies capable of blocking a number of HIV variants have provided researchers with clues to the design of potentially powerful new vaccine candidates. The HIV Vaccine Design Program will use these insights to develop new methods to generate large numbers of potential HIV immunogens and rapidly assess their potential for use in candidate vaccines. Much of the work will take place in a laboratory housed within THSTI that is being built and staffed with support from IAVI, DBT, and THSTI. The program’s location is no accident. Over the past decade, IAVI has enjoyed a productive partnership for the clinical evaluation of candidate AIDS vaccines with key medical research institutions of the Indian government. Indian scientists have also actively participated in an international consortium of HIV laboratories supported by IAVI to advance HIV vaccine research. The government of India, meanwhile, is in the early phase of its “Decade of Innovation,” a policy that seeks to harness a growing roster of home-grown biotechnology companies, the nation’s deep pool of scientific talent, and global research partnerships to boost innovation in a variety of high-tech fields. The HIV Vaccine Design Program provides an opportunity to engage an emerging economy in the global quest to develop a vaccine against HIV. For India, it creates an opportunity to address a crisis of significant relevance to Indians. As importantly, it seeds the kinds of collaborations that often foster scientific and technical innovation and generate ideas that might be applied to address other diseases that have long hampered development.

On the second day of the XIX International AIDS Conference, the need for a host of new tools to prevent and treat HIV and AIDS has already made it to the forefront of the agenda. Of particular note has been the resounding call for a vaccine to prevent HIV, with leading policymakers, scientists, and advocates saying that the world will never reach the end of AIDS without this powerful tool. In a session that focused on improving the effectiveness and efficacy in the HIV and AIDS response, Senator Lindsey Graham (R-SC) said that a vaccine is desperately needed to help make a sizable dent in the pandemic. Graham’s call for a vaccine was echoed by Bill Gates from the Bill & Melinda Gates Foundation. The “ultimate tool” in the fight against HIV and AIDS “will be a vaccine,” Gates said, adding that the US government has been the largest supporter of efforts to develop and vaccine “by far.” He also said that microbicide gels and rings will be powerful prevention products. Without a number of these new tools, the world cannot “talk seriously about moving toward the end” of the pandemic. “We will get these tools, but only if we stay the course.” Later in the afternoon, National Institutes of Health (NIH) Director Francis Collins and Jon Cohen from Science magazine chaired a panel that looked at what lies ahead in HIV and AIDS science. Gary Nabel, director of the NIH’s Vaccine Research Center, said “we’ve never been in a more exciting position” in the search for an HIV and AIDS vaccine. He added that recent discoveries related to broadly neutralizing antibodies over the past two years have made HIV vaccine research “like a phoenix rising from the ashes.” When sharing their hopes for the status of HIV and AIDS research, several panelists also stressed the urgent need to develop new HIV prevention and treatment options. Nabel said that by 2020, he expects researchers will be “in the midst of efficacy trials for an HIV vaccine candidate.” Robert Siliciano of the Johns Hopkins University School of Medicine stressed that by 2020, scientists will be leading clinical trials for new drugs that attack HIV reservoirs. And Dawn Averitt-Bridge of the Well Project said that by 2020, she hopes the world has effective microbicides to prevent HIV, a functional cure for the disease, and that “research makes it into the lives of the people and families we all care so much about.” Cohen ended the session with a call for young people to become the “next generation of scientists” leading HIV and AIDS research. “I’m looking to the young people, because that’s where the revolution is going to happen.” Kim Lufkin is the GHTC’s communications officer.
