Though the World Health Organization (WHO) declared an end to the public health emergency of international concern for COVID-19 back in May, rising COVID cases and new innovations continue to make headlines in December—exemplifying this year as one still dominated by the legacy of the pandemic but also marked by exciting advances in global health research and development (R&D). As the year comes to an end, GHTC reflects on a few of the global health innovation stories that shaped 2023. 1. COVID-19 leaves a complicated legacy of scientific achievement but growing political backlash. While we all hoped the experience of COVID-19 would usher in a new era of proactive health preparedness and improved scientific understanding, 2023 has proved that the legacy of the pandemic is complicated, and history is still actively being written. On the positive side, it has been exciting to see groundbreaking research fueled by COVID-19 funding continue to bear fruit. Applying lessons learned from the pandemic response, researchers and funders alike have sought to accelerate innovative solutions to make countermeasures easier and cheaper to produce, deploy, and administer. For example, this past year brought the announcement of the Biden administration’s more than $5 billion successor to Operation Warp Speed—Project NextGen—to deliver next-generation vaccines and treatments, as well as positive clinical results from Moderna and Pfizer/BioNTech trials on combination COVID-19 and flu shots, and promising research results and funding announcements regarding a variety of needle-free vaccine technologies, including those delivered via nasal spray, inhaler, pen applicator device, and oral film. Taken together, this research could fundamentally alter our approach to controlling COVID-19, as well as ultimately help more people access and benefit from vaccines for a range of deadly diseases. Yet, 2023 could also be characterized as a year of COVID-19 political backlash, particularly in the United States. Fueled by lingering anger over COVID-related public health restrictions, misinformation, and concerns over the origins of the pandemic among their supporters, the Republican-led House of Representatives spent the year calling current and former Biden administration health officials before various subcommittees to testify on their actions, putting science and public health agencies under increasing scrutiny. Additionally, the House has proposed a funding bill for fiscal year 2024 that, if enacted, would slash funding for key agencies that were at the center of the COVID-19 response, including the National Institutes of Health and the Centers for Disease Control and Prevention, as well as cut funding to WHO and limit funding to Chinese government-supported research institutions. Only time will tell whether these efforts ultimately prove more bark than bite or whether they will lead to harmful policies and funding cuts. 2. Attention turns to research on other pandemic and epidemic threats. The year brought no rest for the weary when it comes to emerging infectious disease threats. Alongside managing COVID-19 as a here-to-stay threat, in 2023, the world also dealt with a still-smoldering global mpox outbreak, the conclusion of a Sudan Ebola outbreak in Uganda, and outbreaks of Marburg in Tanzania and Equatorial New Guinea. With these threats looming in the backdrop, researchers forged ahead on efforts to boost future preparedness. The Sabin Vaccine Institute and IAVI launched trials for their Marburg and Sudan virus vaccine candidates, respectively. Gavi, the Vaccine Alliance, also announced this year that some remaining funds from COVAX, the COVID-19 vaccine delivery initiative, would be redirected toward further investigational vaccine candidates for those two deadly viruses. Over the summer, Moderna launched a phase 1/2 trial of its mpox vaccine after having begun preclinical work during last year’s major mpox outbreak. Universal influenza shots and combination COVID-19 and flu shots also saw exciting advances this year, with the National Institutes of Health launching a clinical trial testing an mRNA universal flu vaccine and biopharmaceutical company Osivax’s broad-spectrum influenza vaccine candidate showing strong results. 3. mRNA vaccine technology remains an area of growth, particularly for Africa. The success of mRNA-based COVID-19 vaccines has inspired a flurry of efforts to leverage mRNA technology to address other diseases and potential pandemic threats, as well as to remedy the inequity in access to new tools faced by African countries during the pandemic. BioNTech is advancing mRNA vaccine candidates for malaria, tuberculosis, and HIV, among others, and initiated in April a phase 1 clinical trial to test mRNA vaccine candidates against tuberculosis. This year, newly published research also found that a novel mRNA-based malaria vaccine was effective in animals that had already been exposed to malaria. Additionally, the Coalition for Epidemic Preparedness Innovations this year announced support for a variety of mRNA vaccine candidates against virus families that can affect humans, aiming to create a library of prototype vaccines that can be rapidly adapted as new viral threats emerge. 2023 saw the official launch of the mRNA vaccine technology hub in South Africa, which will pursue vaccines for COVID-19 and other poverty-related diseases to be produced for the African continent. Gavi also announced the African Vaccine Manufacturing Accelerator, which will invest up to $1 billion in boosting African manufacturing, while BioNTech opened an mRNA vaccine factory in Rwanda, which is expected to become part of a decentralized and robust end-to-end mRNA vaccine manufacturing network in Africa. The hope is that these efforts will boost the capacity of African innovators to design, develop, and produce at scale exciting new technologies to tackle diseases with a high burden on the continent and mitigate the equity challenges exposed during the COVID-19 pandemic.  4. Two vaccines for malaria are now recommended. In October, WHO recommended the R21/Matrix-M malaria vaccine, developed by the University of Oxford—two years after recommending RTS,S, the first malaria vaccine—adding another important tool to the world’s arsenal of malaria control interventions. Additionally, results reported in late 2023 about the pilot rollout of RTS,S showed positive findings about the lives it has already saved, making the case for a broader rollout of RTS,S and the potential of integrating R21 into multipronged efforts to fight malaria, as well as hopefully encouraging further innovation in the space. While right now supply of both malaria vaccines remains constrained, manufacturers of both vaccines have agreed to scale up production to meet global demand. 5. Two major firsts for NTDs. 2023 saw two major firsts for innovation against neglected tropical diseases (NTDs), which hopefully will inspire further investment to fill the growing funding shortfalls in NTD R&D. In November, the US Food and Drug Administration announced its approval of the world’s first vaccine against chikungunya, a chronic and debilitating disease that has no specific treatment, which has become an increasing global threat due to climate change. The single-dose shot was developed by Valneva. A month prior, Johnson & Johnson presented new data showing that its pill for dengue fever appeared to protect against a form of the virus in a small human challenge trial done with the Johns Hopkins School of Public Health, providing hope for the first-ever specific treatment for dengue, a serious disease that currently threatens about half of the world’s population, which is similarly a growing threat around the world due to climate change.  6. Setbacks and hope in HIV innovation. Last month brought disappointing news for the global health community as researchers from the PrEPVacc trial that was testing two different HIV vaccine regimens in Africa announced that the study had been shut down after an independent data monitoring committee concluded there was little or no chance the study would demonstrate efficacy. This leaves no efficacy trials underway globally for HIV vaccines.  While this vaccine outcome is certainly discouraging, in more welcome news, 2023 saw exciting developments in efforts to expand affordability and access to long-acting pre-exposure prophylaxis (PrEP) options. In May, Indian drug company Cipla announced that a generic version of cabotegravir long-acting (CAB-LA)—the first long-acting injectable PrEP option—will be manufactured at its plants in South Africa for the first time, which could potentially offer millions of people at risk of HIV infection in Africa access to this drug. In December, GHTC had the privilege of honoring the partners, led by ViiV Healthcare, that developed and are accelerating access to CAB-LA for PrEP for their efforts to advance this groundbreaking new product that could transform global HIV prevention efforts.  2023 also saw Population Council announce that South African company Kiara Health will start producing vaginal rings for HIV prevention in the next few years, which could make the innovative tool cheaper and more readily available to women in Africa. The dapivirine ring, which has been approved by nearly a dozen countries and WHO offers women an alternative long-acting HIV prevention method that can be used discretely without a sexual partner’s knowledge or consent.  7. Urgency and awareness of AMR continues to rise. Over the summer, WHO published its first global research agenda for antimicrobial resistance (AMR), outlining topics and needed tools that researchers should focus on to address its rise. The summer of 2023 also saw the largest ever investment from a country in global AMR surveillance—£210 million from the United Kingdom to support the Fleming Fund’s activities in strengthening surveillance and workforce capacity in countries where the threat of AMR is the highest, including investing in new genome sequencing technologies. This year also saw some exciting announcements about ongoing and upcoming research to address AMR. The Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) received renewed support from G7 governments and launched three funding rounds, which elicited more than 200 applications from around the world. The Global Antibiotic Research & Development Partnership (GARDP) announced positive results from an unprecedented global phase 3 clinical trial testing a first-in-class oral antibiotic to treat uncomplicated gonorrhea, which if approved, will be the first new antibiotic for treating the bacterial infection in decades. Beyond therapeutics, innovation in diagnostics is also essential to addressing AMR. This year, a new study found that a combination of fluorescence microscopy and artificial intelligence was shown to be effective in detecting AMR across multiple antibiotics, a tool that could help health care providers better treat patients with antibiotics and ultimately stall the rise of AMR. 8. Exciting policy developments in the United States and at WHO could boost global health innovation. At the 76th World Health Assembly held in May, member states adopted a historic resolution on strengthening global diagnostic capacity. The resolution, which GHTC advocated for alongside partners like FIND, recognizes the need for countries to prioritize access to appropriate diagnostic tests and calls upon countries to put in place national strategies to expand diagnostic testing and utilize diagnostic data in health decision-making. In November, GHTC also welcomed the introduction in the US House of Representatives of the Supporting Innovative Global Health Technologies (SIGHT) Act, legislation championed by GHTC to empower the US Agency for International Development to boost its health R&D capabilities. The bipartisan bill would create a distinct disease-agnostic program area and budget line for health R&D within the agency’s Global Health Bureau and establish a Chief Innovation Officer for Health position.

The researchers compared the immune system activity of past HIV vaccine study participants to people with HIV who naturally keep the virus from replicating even without antiretroviral therapy, finding that future HIV vaccine candidates may be more successful if they include additional doses or persist longer in the body to continue to stimulate the immune system to deliver the proteins necessary to destroy HIV-infected cells. The research is especially encouraging given the recently halted HIV vaccine trial and hopefully can lead to further advances in the field.Last week, the Global Health Innovative Technology (GHIT) Fund announced that it will invest approximately $8.8 million to accelerate the further development and commercialization of a triple artemisinin combination drug against malaria. Specifically, the investment will support a global, multicenter phase 3 clinical trial project in Africa and Southeast Asia led by Fosum Pharma. The project also includes the development of a co-formulated child-friendly version of the drug, given the high proportion of malaria deaths that occur in children under five. The new drug could also play a role in addressing the rising threat of malaria drug resistance. Recent findings suggest that an inhaled vaccine for COVID-19 delivered directly to the respiratory tract where the virus infects the body could improve protection against infection. The researchers tested COVID-19 vaccine boosters delivered via nasal spray, inhaler, and a shot in the arm in adult rhesus macaques, finding that the inhaled vaccine provided greater mucosal immunity than the other two methods. The promising findings will hopefully further research toward more effective vaccines against COVID-19 and other respiratory viral infections.

The Global Health Technologies Coalition (GHTC) yesterday honored Senator Chris Van Hollen (D-MD) and Congressman Brian Fitzpatrick (R-PA) for their leadership in championing global health research and development (R&D) at its 2023 Innovating for Impact Awards, an annual initiative celebrating US policymakers and partnerships catalyzing global health innovation. GHTC also recognized the partners, led by ViiV Healthcare, that developed and are accelerating global access to cabotegravir long acting (CAB-LA) for HIV prevention—the first and only long-acting injectable option for pre-exposure prophylaxis (PrEP)—for their efforts to advance this groundbreaking new product that could transform global HIV prevention efforts. Senator Chris Van Hollen, who is a member of both the Senate Appropriations Subcommittee on State and Foreign Operations and the Foreign Relations Subcommittee on Africa and Global Health Policy, was honored with a Congressional Champion Award for his longstanding work to grow funding for US biomedical research and global health programs and to advance smart policies to further their impact. “I am pleased to be on the appropriations committee, and not only using that platform to try to fully fund, for example, our efforts at NIH and all of our health research here at home, but also, the research here at home that has a direct benefit to people around the world,” Senator Van Hollen said in accepting the award. GHTC also recognized Congressman Brian Fitzpatrick with a Congressional Champion Award for his leadership in introducing the Supporting Innovative Global Health Technologies (SIGHT) Act to establish a new disease-agnostic research and development (R&D) program at the US Agency for International Development (USAID), as well his support of numerous other bills to bolster product development for tuberculosis, maternal and child health, epidemic preparedness, and antimicrobial resistance. “The United States must remain a world leader in health technology innovation, both at home and abroad. And I personally will always oppose any dangerous cuts to critical agencies that allow our nation to remain a leader in global health,” Congressman Fitzpatrick stated in prerecorded acceptance remarks. GHTC also presented the Partnership Award to Dr. Kimberley Smith, head of research and development at ViiV Healthcare, who accepted the award on behalf of the many partners who have contributed to developing and advancing global access to CAB-LA for PrEP. As a discrete solution that reduces the frequency with which people must take HIV medicine from daily pills to as few as six injections per year, CAB-LA can help more people adhere to PrEP and reduce infections, particularly among at-risk women and girls.  Developed by ViiV, with support from the US National Institutes of Health (NIH) and the Bill & Melinda Gates Foundation, and first approved in the United States in late 2021, CAB-LA for PreP is beginning to be rolled out in low- and middle-income countries (LMICs) through a series of unique public-private partnerships. This includes projects funded by the US President’s Emergency Plan for AIDS Relief (PEPFAR) to support countries in implementing and scaling up CAB-LA, as well as an agreement with the Medicines Patent Pool (MPP) to enable generic manufacturing of the product for use in LMICs.  “It is literally humbling and a tremendous honor to be here to accept this partnership award on behalf of all of the partners,” said Dr. Smith. “This is a game changer, and I'm very much looking forward to the day when we can look back and say that this was the beginning of the end of the AIDS epidemic.Dr. Smith from ViiV was joined in accepting the award by Dr. Jeanne Marrazzo, director of the NIH National Institute of Allergy and Infectious Diseases (NIAID); Dr. Carl Dieffenbach, director of the Division of AIDS at NIH/NIAID; Dr. Emily Kainne Dokubo, deputy global AIDS coordinator for program quality at PEPFAR; Dianna Edgil, chief of the supply chain at USAID; Dr. Myron Cohen, principal investigator of the HIV Prevention Trials Network; and representatives from other organizations involved in advancing CAB-LA for PrEP. “GHTC is thrilled to honor Senator Van Hollen, Congressman Fitzpatrick, and the partners who advanced CAB-LA for PrEP with our Innovating for Impact Awards,” said Jamie Bay Nishi, executive director of GHTC. “History has shown us time and again just how important accessible health technologies, smart policymaking, and multisector partnerships are to confronting global health challenges. We’re delighted to be recognizing the outstanding work of our honorees who are driving innovation to advance global health progress.” During the awards reception, in recognition of 2023 being the year of the World Health Assembly resolution on strengthening diagnostic capacity, GHTC also featured a digital exhibit on diagnostic tools as an often underrecognized driver of global health progress. Now in its seventh year, the Innovating for Impact Awards celebrate US commitment to global health R&D and honor the multisector partnerships and policymakers helping to transform breakthrough scientific research into lifesaving technologies for unmet global health challenges.  View photos from the event on Flickr.Learn more about the initiative and past honorees.

While we know that vaccines, drugs, diagnostics, devices, and vector control innovations are all vital tools in our global health toolbox, in this year of the World Health Assembly resolution on strengthening diagnostics capacity, GHTC wanted to shine a special spotlight on diagnostics as an often underrecognized driver of global health progress. Diagnostics play a critical role for patients, health care providers, and decision-makers, and innovating and improving access to diagnostics are necessary to achieving universal health coverage. The below presentation, which was shared during GHTC's Innovating for Impact Awards reception on December 12, features an explainer of types of diagnostics tests and a glossary of terms, as well as key quotes and facts that demonstrate the critical role of diagnostics.
