GSK’s Arexvy vaccine is a single shot intended for use in adults aged 60 and older and could be available as soon as fall of this year, as long as the US Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices provides further approval. RSV, which has an annual global death toll of 160,000 people, has challenged vaccine researchers for six decades. Building on those years of efforts, GSK’s Arexvy showed strong results in an ongoing trial of nearly 25,000 adults. Further FDA approvals for RSVP vaccines developed by Pfizer, Moderna, and Bavarian Nordic could follow soon, with the decision on Pfizer’s candidate expected as soon as this month.Last week at the 2nd Global Forum on Childhood Pneumonia in Madrid, Spain, the Bill & Melinda Gates Foundation announced a nearly US$200 million commitment, to be awarded over the next year and a half, to support the development and delivery of affordable vaccines for some of the leading causes of childhood mortality, including pneumonia, meningitis, neonatal sepsis, and RSV. This includes supporting a more affordable next-generation pneumococcal conjugate vaccine, Pneumosil, developed by the Serum Institute of India and PATH and advancing a Group B streptococcus vaccine entering phase III trials later this year. The foundation is partnering with the companies developing these vaccines to ensure they are available and affordable to Gavi and low- and middle-income countries, therefore narrowing the gap between the rollout of vaccines in high-income and Gavi-supported countries.A new gold-standard clinical trial in Kenya showed that a single dose of the human papillomavirus (HPV) vaccine may be as effective as two or three doses over at least three years. Deploying a single-dose strategy could dramatically lower the rates of cervical cancer and other associated diseases, as well as extend vaccine supplies, lower costs, and simplify distribution, especially in low- and middle-income countries. At least 24 countries have already shifted to a one-dose approach, and this trial could make it a more widely adopted strategy, which the World Health Organization estimates could prevent 60 million cervical cancer cases and 45 million deaths worldwide over the next 100 years.

Those trials should get underway soon, said WHO officials, as four or five of the 28 potential candidates already have doses ready. In the meantime, contact tracing, isolation, and supportive care are being used to prevent transmission in the countries. A lack of laboratory capacity in Equatorial Guinea has so far prevented the timely identification of cases, but the Africa Centres for Disease Control and Prevention is working to provide technical support, as well as build infrastructure and capacity to improve testing, which will be important in upcoming trials.Last week, the US Centers for Disease Control and Prevention (CDC) warned about the recent, rapid spread of the drug-resistant fungus Candida auris, or C. auris, in health care facilities and highlighted the serious risk the fungus poses to immunocompromised individuals. C. auris is resistant to typical antifungal treatments, and developing a vaccine for the fungus would likely take many years. There are currently no approved vaccines for any form of fungal infections. One vaccine candidate, being developed with support from the US National Institutes of Health, is designed to be cross-protective against several fungal pathogens, potentially including C. auris, although a phase 1 clinical trial is over a year away.Executives at three of the world’s leading flu vaccine manufacturers—GSK, Moderna, and CSL Sequiris— have said that they are preparing the capacity to develop hundreds of millions of avian flu shots within months if a new strain of avian flu jumps to humans. The companies are already or will soon begin testing sample human vaccines that match the subtype currently circulating among birds and mammals. Sanofi has also expressed its readiness to begin production, alongside its stock of existing H5N1 vaccines. However, there is concern about how to ensure equitable global access to such vaccines in the case of an outbreak, given a substantial portion of doses are already reserved for wealthy countries through preexisting preparedness contracts.

The 2022 midterm elections on November 8 were expected to deliver a decisive power flip from Democrats to Republicans. However, as the new landscape comes into focus, it appears that Democrats will hold the Senate, and Republicans are likely to win the House of Representatives by a handful of seats. These margins and the composition of new committees will determine the trajectory of global health research and development policy over the next two years.Both chambers on a knife edge splitRepublicans underperformed most analysts’ projections in both chambers. In the House, they are expected to eke into power by only a handful of seats. In the Senate—where several Republican candidates failed to overtake their competitors in close races—Democrats have retained control and may even net gain one seat, depending on the outcome of a special runoff election in Georgia on Tuesday, December 6, between incumbent Senator Raphael Warnock (D) and Herschel Walker (R).Implications on makeup of key committeesNext steps for both parties include electing new party leaders, which is expected to happen later this year. Following that, early next year, the parties will designate committee assignments, which will impact oversight and policymaking for the next two years of global health research. In the House, committee majorities will be determined by who holds the majority in the full House. In the Senate, if the final split is 50-50, then committees will also be evenly split. But if Senator Raphael Warnock wins his reelection in Georgia, then the Senate will be 51-49, and Democrats will take the majority on each committee with one extra seat.Though we do not yet know exactly how the committees will look next year, we do know which members from the 117th Congress will return to the 118th and which current members will be stepping down.Leadership of most committees relevant to global health research and development (R&D) are expected to remain relatively stable with top Democrats and Republicans trading positions as chairs and ranking members. Some exceptions include Representative Karen Bass, chairwoman of the Subcommittee on Africa, Global Health, Global Human Rights and International Organizations, who is stepping down in pursuit of becoming the next mayor of Los Angeles and Rep. Hal Rogers (R-KY), ranking member of the House Appropriations State, Foreign Operations, and Related Agencies Subcommittee, who may become chair of the subcommittee or may be replaced by Rep. Mario Diaz-Balart (R-FL).Among the members currently serving on the House Foreign Affairs Committee who have retained their Congressional seats are Reps. Susan Wild (D-PA), Maria Elvira Salazar (R-FL), Young Kim (R-CA), and Abigail Spanberger (D-VA). Members who were defeated include Reps. Tom Malinowski (D-NJ) and Steve Chabot (R-OH). Some other members of Congress on relevant appropriating and authorizing committees to global health research who are retiring or lost their primaries earlier this year include Reps. Albio Sires (D-NJ), David Price (D-NC), Lucille Roybal-Allard (D-CA), Cheri Bustos (D-IL), Jaime Herrera-Beutler (R-WA) and Fred Upton (R-MI). In the Senate:There were no major losses among incumbents on the Foreign Relations Committee; Health, Education, Labor, and Pensions (HELP) Committee; or the Appropriations Labor, Health, nor on the Human Services, Education, and Related Programs (LHHS) and State and Foreign Operations subcommittees. Some big names will be retiring, including Sens. Richard Shelby (R-AL), ranking member on the Appropriations Committee; Roy Blunt (R-MO), ranking member on the LHHS Subcommittee; Richard Burr (R-NC), ranking member on the HELP Committee; and Rob Portman (R-OH).Some leadership changes are expected. Sen. Patty Murray, previous chair of the Senate HELP Committee, is expected to become the head of the Senate Appropriations Committee. The Senate HELP Committee will likely be led by Sen. Bernie Sanders (I-VT) and Sen. Rand Paul (R-KY) or Sen. Bill Cassidy (R-LA). The Senate LHHS subcommittee may be led by Sen. Joe Manchin (D-WV) and Sen. Marco Rubio (R-FL). Both 2022 GHTC Innovating for Impact award winners, Sen. Sherrod Brown (D-OH) and Sen. Todd Young (R-IN) retained their seats.  A potentially challenging landscapeWith Democrats elected to retain control of the Senate in the 118th Congress, leadership in both parties of the current Congress may be more interested in passing an end-of-year funding package so that the 118th Congress can begin with a clean slate. The same may not be true next year, though. If Republicans have a slim majority in the House as projected, it could empower more conservative members to dangle threats to regular governance, such as annual passage of an appropriations package, as bargaining chips—a threat some members have already referenced. Such a dynamic may also lead to hardball negotiations over raising the debt ceiling, a final agreement on which is due in July of next year. Ultimately, these dynamics could limit the potential for global health R&D funding growth in the next two years, despite the need for greater resources. Beyond the funding picture, if Republicans win control the House, they plan to increase oversight over many US government agencies, including several public health and research agencies such as the National Institutes of Health and the Centers for Disease Control and Prevention. Oversight over the executive branch is a critical function of Congress, but aggressive oversight can also threaten the basic functioning of these agencies as staff efforts are redirected. This could ultimately impact the pace of progress for global health research and science in general.Looking aheadGlobal health R&D has historically received bipartisan support, yet this will be the first Congress to be seated after the COVID-19 pandemic, a global health catastrophe that has provoked some policymakers to question the value of certain types of research and the global health status quo. The results of this election are still being finalized, but regardless of who is in charge, there will remain opportunities for crafting and passing good policy. Whether progress happens and at what pace will largely depend on the ability of advocates to make the bipartisan case for why global health R&D is a force multiplier for creating a healthier and safer future for Americans and all global citizens.
