Breakthroughs Blog: COVID-19

The COVID-19 pandemic has revealed a collective failure to take pandemic prevention, preparedness, and response seriously and prioritize it appropriately, according to a report released this week by the Global Preparedness Monitoring Board (GPMB)—an independent panel co-convened by the World Bank and World Health Organization (WHO) to offer policy recommendations on pandemic preparedness. As a result, the world is paying a hefty price in economic and health losses, the report stresses. Vaccination campaigns around the world have been suspended, threatening polio eradication and potentially leading to new outbreaks of preventable diseases. Interrupted access to HIV/AIDS, tuberculosis, and malaria care threatens to cause more than 1 million additional deaths in 2020-2021 alone. Meanwhile, the costs of this pandemic have already been measured in the trillions of dollars, while the costs of preparedness are billions. GPMB representatives have noted it would take 500 years to spend as much on investing in preparedness as the world is losing due to COVID-19. In their inaugural report last year, GPMB stressed the inadequacy of systems and financing required to detect and respond to health emergencies. As COVID-19 has proven, these systems remain dangerously deficient and under-resourced. This year’s report, “A World in Disorder,” highlights five calls for urgent action: 1) responsible leadership; 2) engaged citizenship; 3) strong and agile national and global systems for global health security; 4) sustained investment in prevention and preparedness, commensurate with the scale of a pandemic threat; and 5) robust global governance of preparedness for health emergencies. Three of the five recommendations connect to strengthening the global health research and development (R&D) ecosystem.  A call for strong and agile national and global systems for global health security In its 2019 report, GPMB called on heads of government to “appoint a high-level coordinator and invest in research and development for countermeasures and non-pharmaceutical interventions, along with mechanisms for sharing genome sequences of new pathogens, and for equitable allocation of scarce medical countermeasures.” The need for this has been apparent throughout the COVID-19 pandemic, as uneven and uncoordinated responses have hampered efforts to flatten the curve.  This year’s report doubles down on the need for greater coordination and highlights the need for formal global mechanisms to facilitate the development, assessment, and distribution of diagnostics and medical countermeasures. The following recommendation and the supporting points underscore this priority: “Urgent action: Researchers, research institutions, research funders, the private sector, governments, the World Health Organization and international organizations improve coordination and support for research and development in health emergencies and establish a sustainable mechanism to ensure rapid development, early availability, effective and equitable access to novel vaccines, therapeutics, diagnostics and non-pharmaceutical interventions for health emergencies, including capacity for testing, scaled manufacturing and distribution.” Progress has been made on a coordinated R&D response but remains fragile. Scientists and researchers around the globe have raced with record speed to develop and assess countermeasures. This progress is based on past investments and existing infrastructure for basic research, as well as new frameworks and initiatives, including the Access to COVID-19 Tools (ACT) Accelerator, which highlights the need to work more collaboratively not just across different geographies, but with the end-to-end process in mind. Yet GPMB highlights that it remains to be seen whether these initiatives can deliver on their promise, or whether they will expand their scope beyond the current pandemic. What is certain is that if these endeavors are to be successful, they will need serious investment. ACT Accelerator partners estimate they will need US$35 billion to fund this initiative, of which $15 billion is needed by the end of this year. GHTC has been working diligently behind the scenes with government, private sector, and civil society stakeholders to push for greater collaboration, ensure world leaders leverage these mechanisms in the future, and use the current focus on the pandemic to establish more sustainable financing mechanisms for R&D to confront future health threats. Global preparedness is not simply the sum of national preparedness. The GPMB report highlights the need for global agreements or mechanisms to share information and allocate limited supplies of countermeasures. The expert panel notes that while “national preparedness is key, global and regional mechanisms for tracking potential pathogens, early alert, information sharing, research and development, regulatory capacity-building and harmonization, allocation of countermeasures, stockpiles and supply chains must also be strengthened and developed, sustained and financed. Preparedness to conduct rapid research and countermeasure development requires sustained commitment to capacity-building and funding for basic science research.” Past pandemics have shown that without clear frameworks and procedures to facilitate the equitable sharing of limited medical countermeasures, low and middle-income countries (LMICs) may be unable to secure access to the innovative medical products they need. GHTC believes that as instruments such as the COVID-19 Global Vaccine Access (COVAX) Facility are stood up, it is important to ensure that the world leaders look beyond the current pandemic and establish sustainable mechanisms that will outlast COVID-19 to support the range and scope of R&D necessary to confront health emergencies in the future. Manufacturing capacity, stockpiling, and supply chains have become major bottlenecks. When COVID-19 struck, most countries did not have sufficient stockpiles of medical countermeasures or the pre-existing capacity and resources to suddenly scale up manufacturing to respond to a pandemic. This created a major surge in global demand and exposed the fragility of global supply chains for medical goods. In LMICs that cannot afford bidding wars, it has been extremely challenging to source personal protective equipment, testing materials, treatments, and medical equipment. Over the past decade, the manufacturing of vaccines, therapeutics, and diagnostics has become increasingly concentrated in a few countries, which has exacerbated the risk of ruptures and has proven detrimental to the equitable distribution of health products. This shortage of manufacturing capacity for medical countermeasures has threatened countries’ capacities to fight COVID-19.  A global coordination mechanism can support regional capacity building in LMICs. GHTC is urging world leaders to create a global institution or broaden the mission of an existing mechanism like the Coalition for Epidemic Preparedness Innovations (CEPI) that can coordinate and galvanize biomedical research expertise and advance health products to respond to emerging health threats. This institution should also work closely with countries to improve regional capacity, provide technical assistance, and highlight where there may be a need for additional strategic investments to support preparedness capabilities.  A need for sustained investment in prevention and preparedness, commensurate with the scale of a pandemic threat As seen previously with Ebola, and now with COVID-19, the cost of response is far greater than preparedness due to massive economic disruption caused by pandemics. It also demonstrates the urgent need for global financing mechanisms to accelerate national health preparedness and prevention capacity, including for biomedical research, development, and manufacturing. The GMPB report follows the calls of many experts, articulating the need for new health security financing incentives and investment accountability. The following recommendation from the report highlights the need for international financing for R&D: “Urgent action: The World Bank and other International Financial Institutions (IFI) make research and development (R&D) investments eligible for IFI financing and develop mechanisms to provide financing for global R&D for health emergencies.” Extraordinary events require extraordinary financing. The world urgently needs a robust, dedicated global health security funding mechanism to catalyze and accelerate the necessary investments that will help prevent the next pandemic. The GPMB expert panel argues in its report that rapid financing of emergency R&D and capacity-building is hampered by the lack of mechanisms in IFIs to provide such financing at the global level. Many experts believe that new mechanisms are needed, and some— including GHTC—believe that the World Bank’s Health Emergencies Preparedness and Response Fund (HEPRF) can fill that role by financing some short-term R&D capacity-building programs. This includes rapidly increasing regional diagnostics manufacturing and laboratory capacity, expanding clinical trial capabilities in LMICs for COVID-19 health products, and supporting regional regulatory processes to speed the uptake and use of these new technologies. Advocates have also pushed for innovative financing models such as a Global Health Security Challenge Fund to close the massive global gaps in pandemic preparedness.  Robust global governance of preparedness for health emergencies is vital for global security COVID-19 has highlighted significant gaps in the governance of preparedness. Key issues have arisen around the functioning and implementation of the International Health Regulations (IHRs), which countries have committed to meet, and our current mechanisms are inadequate to fully respond to the crisis or help catalyze and coordinate R&D for medical countermeasures. The GPMB recommendation below highlights the need to galvanize world leaders to develop a new governance framework for global preparedness through a United Nations (UN)–led forum: “Urgent action: The Secretary-General of the United Nations, the Director-General of the World Health Organization, and the heads of International Financing Institutions convene a UN summit on Global Health Security, with the aim of agreeing on an international framework for health emergency preparedness and response, incorporating the IHR, and including mechanisms for sustainable financing, research and development, social protection, equitable access to countermeasures for all, and mutual accountability.” Current measures of preparedness are not predictive. The GPMB expert panel asserts that our understanding of preparedness is based on a narrow set of public health capacities that does not fully capture the range of national and international capacities necessary to ensure preparedness, including R&D, measures to mitigate the socioeconomic impacts of epidemics and ensure continuity of essential services, international cooperation, and the preparedness of international organizations. This underscores a problem GHTC has raised for several years, namely that while it has never been more apparent that R&D for health technologies and medical countermeasures is vital to enhance our capacity to prevent and combat threats as they emerge, capacity-building of R&D for medical countermeasures including diagnostics is noticeably absent from IHRs and the Global Health Security Agenda. In order to address current and future pandemics, it will be essential to ensure that R&D is integrated formally into both. While not every country needs a full suite of R&D capabilities for vaccines, diagnostics, therapeutics, and other technologies like personal protective equipment and oxygen therapies, GHTC believes every country should have a plan and pathway to gain access to these tools at an affordable price when needed. Final thoughts: GPMB highlights that the pandemic is a stress test for global solidarity and multilateralism One of the greatest challenges of the COVID-19 pandemic is faltering multilateral cooperation. While a plethora of new initiatives have emerged to combat the coronavirus, nationalistic attitudes and political tensions have hampered the global response. We have seen this year that disagreements over the adequacy of WHO’s response to the pandemic, as well as continued diplomatic strife between the United States and China have complicated the implementation of a collective response and stalled progress in the G7 and G20, with both fora failing to develop or publish strong consensus resolutions or roadmaps. The report makes it quite clear that we are at a fork in the road when it comes to this crisis. We can either choose to take bold collective action and strengthen the multilateral system, with a strengthened focus on gaps like R&D capacity, or retreat into nationalism. COVID-19 will remain a protracted crisis without global collaboration, and now is the time to strengthen the global health security R&D architecture of the future to ensure that we are prepared for the next pandemic.

On Saturday, the company announced the UK trials of its vaccine candidate would resume, citing the conclusion of its investigation into the adverse reaction. AstraZeneca’s clinical trials in the United States, Brazil, and South Africa remain paused. No further details on the affected participant or illness have been released, to protect patient confidentiality. The UK trial continuation was greenlit by Britain’s regulatory authority, and the review process included analysis from independent boards overseeing trials on several other COVID-19 vaccine candidates.German diagnostic test maker Qiagen plans to launch a COVID-19 antigen test that processes about 30 samples per hour and provides results within 15 minutes. The company plans to launch two versions of the test in November, one for labs and one for point-of-care use, and has not yet received authorization from the US Food and Drug Administration (FDA). Studies on the diagnostic indicated 100 percent accuracy in identifying those without the disease and at least 90 percent accuracy in identifying those with the disease. The test uses an eHub, a small portable device, to analyze nasal swab samples. Qiagen expects to be able to produce several million tests per month when it launches and scale up to more than 10 million per month in 2021.The United States has indicated it will not participate in the COVID-19 Vaccine Global Access (COVAX) Facility, a global effort to develop and distribute COVID-19 vaccines effectively and equitably. The initiative—co-led by the World Health Organization (WHO), the Coalition for Epidemic Preparedness Innovations (CEPI), and Gavi, the Vaccine Alliance—currently includes more than 170 countries and hopes to work against “vaccine nationalism,” which WHO Director-General Dr. Tedros Adhanom Ghebreyesus has said exacerbated the pandemic and supply chain failures. The Trump administration said the United States will continue to work toward a vaccine that maintains FDA standards.

Three new studies, recently published in the journal JAMA, support the use of steroids to treat severely ill COVID-19 patients, generating mounting evidence that these common drugs are the most effective treatment for the virus found to date. The use of steroids to treat COVID-19 had been under debate over the last few months, as some worried that they could prevent the body from fighting off the virus effectively as a side effect of tamping down the immune system’s potentially deadly overreaction to infection. Dexamethasone, a steroid that was found to reduce deaths among the most serious COVID-19 cases, has been in use in some areas since a major June UK study demonstrated its efficacy. The new research, published jointly by three different global teams, further backs the use of dexamethasone as well as another steroid, hydrocortisone. Positive results on steroid use are especially significant because of their wide availability and inexpensive prices, making them an accessible treatment option.Study results released last week, gathered from tests on more than 30,000 people in Iceland analyzing immune response to COVID-19, found evidence of a lasting antibody presence post-infection. Previous smaller studies have suggested COVID-19 antibodies might disappear quickly after infection, making the unknowns of lasting immunity and future infection a question of interest for researchers. The new study, conducted by Amgen-subsidiary deCODE Genetics, used nasal swabs and blood samples from 30,576 individuals to examine infection levels and immune response. Results showed that after the first wave of antibodies, which may fade after a month or two as other studies have reported, a longer-lasting second wave of antibodies forms, which was shown to remain stable for four months. While these findings are not necessarily applicable to all countries’ populations, and several unknowns remain, the results provide an optimistic sign for vaccine makers hoping to confer long-lasting COVID-19 immunity.The National Institutes of Health (NIH) is backing nine additional COVID-19 test manufacturers as part of its Rapid Acceleration of Diagnostics initiative (RADx), adding US$129.3 million in funding to scale up production of point-of-care screening tests and high-throughput laboratory assays. Many of the test candidates are using innovations that have moved from labs to point of care in five to six months—a process that usually takes years—according to NIH National Institute of Biomedical Imaging and Bioengineering (NIBIB) Director Bruce Tromberg. NIBAB helps lead RADx, which hopes to deliver products and services to the public this fall.

The US Food and Drug Administration (FDA) last week granted emergency use authorization (EUA) to a rapid, inexpensive COVID-19 diagnostic test developed by Abbott Laboratories that delivers results within 15 minutes. The test, which works by detecting antigens unique to SARS-CoV-2, is the first COVID-19 antigen diagnostic that does not require specialized equipment to read the results. The diagnostic does require a health care professional to obtain a nasal swab from the patient, which is then inserted into a credit card–sized device. A strip inside changes color if SARS-CoV-2 proteins are detected. Abbott has said the company intends to produce tens of millions of the diagnostic in September and 50 million in October, to be priced at US$5 per test.The National Institutes of Health’s (NIH) National Center for Advancing Translational Sciences (NCATS) will begin studies on GS-441524, a compound similar to remdesivir, as a potential treatment for COVID-19. The compound, developed by Gilead, has not yet been tested in humans, but research suggests it works in the same way as remdesivir and is active against SARS-CoV-2. Gilead says it has primarily pursued remdesivir due to evidence that it is more effective than GS-441524 at blocking viral replication in test tubes and animal models and was more active against multiple coronaviruses in lab tests. Other researchers have said GS-441524 could have similar or superior effects to remdesivir, is more easily synthesized enabling easier creation of oral versions, and does not cause much toxicity. NCATS expressed its intention to further study the compound in an August 20 letter and has said it expects to conduct studies quickly and make results available to the research community.Scientists are looking into an alternative vaccine delivery route to combat COVID-19: nasal sprays. The majority of vaccines—and all current COVID-19 vaccine candidates in clinical trials—are delivered as an injection into muscle to optimize the human immune response and prevent people from becoming sick. A nasal spray, some researchers say, could be more effective in helping to prevent the spread of disease, as COVID-19 infection can take hold in the nose or throat before systemic immunity from a vaccine kicks in, allowing infection to still spread to others. The nasal spray could provide a local immune response in the nose and throat as well as a systemic response through the entire body. Multiple researchers are in early stages of developing nasal spray vaccines, including one with inspiration from an existing nasal spray flu vaccine.
