A landmark study found that men whose HIV infection was fully suppressed by antiretroviral drugs had no chance of infecting their partner—suggesting that if everyone with HIV were fully treated, there would be no further infections. Of the nearly 1,000 male couples across Europe who participated in the study, in which one partner with HIV was receiving treatment to suppress the virus, there were no cases of transmission of the infection to the HIV-negative partner during sex without a condom. According to Professor Alison Rodger, co-leader of the paper published in The Lancet, these findings “provide conclusive evidence for gay men that the risk of HIV transmission with suppressive ART [antiretroviral therapy] is zero” and that the study’s findings “support the message of the international U=U campaign that an undetectable viral load makes HIV untransmittable.” The Global Polio Eradication Initiative (GPEI) unveiled a new five-year strategy on Tuesday, which includes the use of novel oral polio vaccines—several of which are being developed by PATH and its partners—as well as the adoption of smartphone technologies to assist in disease surveillance and faster response. GPEI is also planning to establish a regional hub in Amman, Jordan to allow for easier coordination and increased technical support for polio vaccination programs in Afghanistan and Pakistan, two polio-endemic countries. Additionally, as part of the new strategy, GPEI is expanding its partnership with development institutions such as Gavi, the Vaccine Alliance. These new approaches, among others, will be implemented by GPEI under its new strategy from 2019-2023 in the hopes that this new strategy will be its last, with wild poliovirus successfully eliminated by 2023. The new strategy is currently facing a funding gap of US$3.27 billion, which organizers hope to fill with a pledging conference in November. On Wednesday, the US Food and Drug Administration (FDA) approved the first vaccine against dengue fever. The vaccine, Dengvaxia, has generated much controversy in recent months due to post-marketing research performed by its manufacturer, Sanofi Pasteur, which showed that the vaccine offers protection for people who have already had at least one bout of dengue, but increases the risk of severe infection in children who were dengue-naïve, or never infected when they were vaccinated. The FDA ruled that Dengvaxia can only be administered to individuals between the ages of 9-16 living in parts of the United States where the dengue virus is endemic, and that it can only be given to children and young adults who had one previous laboratory-confirmed case of dengue. Identifying these individuals with prior infection is currently a challenge, because there is no point-of-care diagnostic test available, though Sanofi officials say they have to have one ready for FDA submission by late 2020. Sanofi will earn a priority review voucher (PRV) by bringing Dengvaxia to market. A PRV is an incentive created to encourage pharmaceutical companies to develop drugs and vaccines for neglected diseases and, in exchange, allows a company to expedite the review of another product it wants to bring to market or sell the voucher to another company.

The Trump administration’s budget request for fiscal year 2020 (FY20) includes cuts that—if enacted—would hamstring the research and development (R&D) of new global health technologies funded by the National Institutes of Health (NIH), Centers for Disease Control and Prevention (CDC), US Agency for International Development (USAID), and Department of Defense (DoD). Since the release of the budget request in early March, however, lawmakers from both parties have expressed their commitment to shielding these critical funding strings from the president’s scissors.Among the proposed cuts is a 12 percent reduction for NIH. On April 11, the Senate Appropriations Labor, Health and Human Services, Education, and Related Agencies Subcommittee (LHHS) held a hearing to review the budget request for NIH. From the beginning, it was clear the administration’s proposal would face bipartisan pushback. Subcommittee Chairman Roy Blunt (R-MO), in his opening remarks, said, “I'm disappointed, of course, that the 2020 budget request would cut the agency by 13 percent. I'm confident that this committee will not do that, but we'll talk to you today about the reasons that we should continue in the direction we're in rather than head in another way.”Chairman Blunt was followed by Ranking Member Patty Murray (D-WA), who delivered an even stronger rebuke: “At a time of remarkable possibility in medical research, a time where we can and should continue leading the world in medical discovery, the Trump administration wants to cut funding for NIH… President Trump's damage -- damaging budget is wildly out of step with the sentiments of Congress, thankfully, and the American people. And I feel confident, working with our Chairman, that we will once again reject it.”Later in the hearing, Senator Richard Shelby (R-AL), who serves as Chairman of the full Senate Appropriations Committee, also voiced his support for an NIH funding increase:“What you do is more important than most [of] what we do in America. I'm not interested in cutting your budget. I'm interested in increasing it…I think this is a great investment for America, for the world, for humanity, what you do… it's not only a financial investment, which is good for the economy. It is the leading scientists, the cutting edge of scientific research that you add. And we all benefit from it immensely.”The week prior, the House Appropriations LHHS Subcommittee had held their hearing on the NIH budget. Subcommittee Chairwoman Rosa DeLauro (D-CT) said that Congress would reject proposed funding cuts to the NIH. In her opening statement she emphasized the value of scientists’ work: "Funding [biomedical] research has the power to do more good for more people than almost anything else within the purview of this subcommittee.”Referring to the administration’s newly launched effort to end the transission of HIV and AIDS in the United States, Chairwoman DeLauro continued: “Decades of research supported by NIH led to the development of the very treatment and prevention approaches that have put achieving this goal within reach, specifically antiretroviral therapy and PrEP. The NIH must be involved, if we are to continue to make progress in reducing HIV and AIDS, domestically and abroad.”In other budget hearings, lawmakers focused on important funding sources for global health R&D outside of NIH—including the DoD. In the House Appropriations Defense Subcommittee hearing on the US Army budget on April 9, Rep. Betty McCollum (D-MN), Vice Chair of the Subcommittee and Co-chair of the House Global Health Caucus, pressed the Secretary of the Army and Army Chief of Staff about proposals to divert funding from malaria vaccine research funded by the US Army: “Given that malaria remains the number one infectious disease threat for troops deployed in these regions, and we know that we have issues with [treatment] compliance, whether it’s State Department, military, even Peace Corps volunteers because of the side of effects from these diseases, it remains critically important that the Army’s research on malaria vaccines continue. I’m concerned in the FY20 budget that the justification appears that the funding for the project that conducts malaria vaccine research is being realigned into other projects. Given nearly all the most effective widely-used anti-malarials were developed in part by the US military research team, I find the possibility of losing momentum in research extremely alarming.” With the ongoing outbreak in the Democratic Republic of the Congo (DRC), Ebola is another infectious disease high on lawmakers’ radar. On March 14, the Senate Appropriations LHHS Subcommittee held a hearing on the Ebola outbreak in DRC and other emerging health threats. Subcommittee Chairman Blunt’s (R-MO) opening statement emphasized, “It is clear that our investments to improve global health have a direct impact on the wellbeing of every American.” He highlighted recent funding increases he has championed for the NIH National Institute for Allergy and Infectious Diseases, the CDC, and the Global Health Security Agenda. Senator Richard Durbin (D-IL) also expressed his support for global health research: “If you wanted to look at the most important room in Washington, DC, when it comes to medical research over the last few years, it would be this room, this subcommittee. Under the leadership of Chairman Blunt and Senator Murray, we have seen for four straight years a 5 percent increase and real growth at the NIH. I think an overall 30 percent over that period of time, the 5 percent real growth each year. Increases to the CDC I wish were equal, but they had been good. We hope they'll get better in the future. I reject the President's budget out of hand. This notion of 12 percent cut to the NIH is just unacceptable and I think most Democrats and Republicans would agree.”In addition to defending investments in biomedical R&D, lawmakers have expressed support for funding for international aid and development—which would be cut by 24 percent under the President’s budget proposal. On February 27, the House Appropriations State and Foreign Operations Subcommittee held an oversight hearing on USAID Programs and Policies. In her opening statement, Appropriations Committee Chairwoman Nita Lowey (D-NY) emphasized the value of USAID, stating, “Failing to maintain our position as the leader in global development and humanitarian assistance will cost lives, risk the spread of infectious diseases, and reduce American influence around the world.” Included in the budget proposal is a US$1.35 billion reduction to the President’s Emergency Plan for AIDS Relief (PEPFAR). In response, several lawmakers vigorously defended the United States’ role in addressing the international HIV and AIDS epidemic. On March 6, Rep. Eliot Engel (D-NY), Chairman of the House Foreign Affairs Committee, said, “I'm particularly opposed to cuts in funding for global AIDS programs. There's a 22 percent cut in PEPFAR used to treat millions internationally, mostly in Africa.” Later that month, Rep. Karen Bass (D-CA) also defended PEPFAR: “The administration has maintained most Africa focused aid initiatives launched by previous Congresses, and in some cases have sought to fund them, however at far lower levels. These include the global President's Emergency Plan for AIDS or PEPFAR…and I'm glad that those initiatives have continued but concerned about the cuts in funding. I will conclude by stressing…that US relations with Africa has always enjoyed bipartisan support here in Congress, and we expect to continue to work together. Each time the administration has sought to reduce funding, the State Department or USAID, especially those that would impact African countries, we have worked together in a bipartisan manner to restore that funding.”In early April, Rep. Eliot Engel (D-NY) again affirmed his belief “in development as a way to advance American interest and security that’s rooted firmly in our values.” In reaction to the President’s budget proposal, he noted that, “Tuberculosis and malaria and AIDS patients all around the world” would be pushed aside by the “heartless and harmful approach to foreign policy.” The Trump administration’s budget request, if enacted, would slash funding for lifesaving research, development, and implementation of new global health technologies. Fortunately, lawmakers, with support from advocates, have diligently opposed these cuts. It’s our job to ensure this continues.
