The initial investment of up to US$850,000 will go toward a proof-of-concept of the company’s bio-responsive polymeric nanoparticle platform technology. If effective, the technology could help make major strides in access to mRNA vaccines, which transformed the global response to COVID-19 and have the potential to address a number of other diseases but require cold storage, which creates access challenges to these products, especially in low resource settings.A recent study in The Lancet found that an experimental vaccine against Marburg virus was safe and produced an immune response in a small, first-in-human phase 1 clinical trial. The candidate, cAd3-Marburg, was developed at the National Institute of Allergy and Infectious Diseases’ Vaccine Research Center and uses a vaccine platform called cAd3, which previously demonstrated a good safety profile in investigational vaccines developed for Ebola virus and Sudan virus by the center. Further trials of the vaccine candidate are planned in Ghana, Kenya, Uganda, and the United States, which could propel the candidate as a viable tool in the response to outbreaks of Marburg virus.2022 saw a handful of milestones in the fight against neglected tropical diseases (NTDs) with Togo becoming the first country to eliminate four of the diseases and Malawi eliminating trachoma, among other achievements. However, to address the major challenges that remain, funding for the research and development (R&D) of improved treatments and diagnostics will be crucial. New medicines to treat NTDS are urgently needed as current treatments medicines are often ineffective, intolerable, or entirely absent. While promising innovations for treatments against sleeping sickness and visceral leishmaniasis, among others, are in the pipeline, collaboration and partnerships will be necessary to catalyze further innovation and development.

Following Africa’s major challenges in accessing COVID-19 vaccines during the pandemic, the investment aims to ensure the production of vaccines for low- and middle-income countries during future health crises, and to increase African autonomy over regional health security efforts. The first round of funding includes $15 million over three years, which will fund the development of manufacturing facilities. Last week at the World Economic Forum’s annual meeting in Davos, the World Health Organization (WHO) announced plans to set up a new TB Vaccine Accelerator Council to catalyze the development of tuberculosis (TB) vaccines. In launching the plan, WHO Director-General Dr. Tedros Adhanom Ghebreyesus noted the lesson learned during the pandemic that global, cross-sector commitments and partnerships can accelerate the vaccine research and development process. In addition to stressing the importance of strong TB programs and commitments from high-burden countries, the speakers at the launch event urged countries to renew their commitment toward combating TB by reinvigorating research efforts that have been historically stagnant.Also, at the meeting in Davos, Pfizer announced that it will make its entire portfolio of 500 drugs and vaccines available to 45 low-income countries at nonprofit prices. This collection of medical technologies includes patented and off-patient medicines, a range of antibiotics, as well as new vaccines and medicines as they are launched. This effort is an expansion of last year’s “An Accord for a Healthier World” initiative, which focused on a smaller number of patented products, including the COVID antiviral treatment Paxlovid. The initiative will provide more than a billion people access to important products, hopefully helping to address major global health challenges, including antimicrobial resistance which has arisen in part, due to challenges accessing a broad scope of treatments.

Hetero also announced a licensing agreement with the Medicines Patent Pool to manufacture and sell the generic version in low- and middle-income countries. WHO’s inclusion will hopefully improve access for the drug, which the agency has strongly recommended for the treatment of high-risk patients with mild and moderate COVID-19, but which has been largely inaccessible to patients in low- and middle-income countries.Recent findings published in the New England Journal of Medicine found that initial results from two phase 2 clinical trials showed that two vaccines (Ad26.ZEBOV (Ad26) followed by MVA-BN-Filo (MVA) 56 days later and rVSVΔG-ZEBOV-GP (rVSV)) given with or without a booster dose 56 days later) against the Zaire strain of Ebola virus are safe and well-tolerated in adults and children. Both vaccines produced antibody responses as soon as two weeks after administration of the first dose that lasted for at least a year. As part of the PREVAC study in West Africa, these trials aim to assess the safety and efficacy of different experimental vaccine regimens for Ebola Zaire vaccines in order to reduce the high mortality associated with Zaire outbreaks.An innovative, new vaccine for HIV developed by the Scripps Research Institute in collaboration with the Fred Hutchinson Cancer Center, the International AIDS Vaccine Initiative, and the US Institute of Allergies and Infectious Diseases, among others, has demonstrated promising results in its first immunogenicity trial in humans. In response to HIV exposure, the vaccine, called eOD-GT8, is designed to induce a type of broadly neutralizing antibodies that can block a specific part of the virus that is needed for it to enter certain cells. While extensive further research and many further challenges remain, the recent results do demonstrate the potential of a complex and innovative approach.

The support is aimed at helping improve the quality of antimalarial products to meet World Health Organization’s (WHO’s) standards in order to increase the use of locally produced drugs and make them eligible for bulk procurement by global institutions, as well as to address the high burden of malaria on the continent. This effort is also part of a wider initiative to increase African manufacturing after COVID-19 uncovered the risks of the continent’s over-reliance on imported drugs. The Bill & Melinda Gates Foundation and the Coalition for Epidemic Preparedness Innovations (CEPI) are investing US$30 million in Aspen Pharmacare Holdings Limited to support the manufacturing of routine and outbreak vaccines for Africa. Through a ten-year agreement with the Serum Institute of India, Aspen will use the investment to manufacture and distribute the routine Pneumococcal, Rotavirus, Polyvalent Meningococcal, and Hexavalent vaccines, as well as support technology-transfer activities and build regional vaccine manufacturing capacity for potential future outbreaks. The investment underlies a wider effort to ensure vaccine manufacturing capacity and supply of affordable vaccines on the continent. Joining a growing call for action in response to the increasing threat of antibiotic resistance, WHO recently published the Global antimicrobial resistance and use surveillance system (‎GLASS)‎ report: 2022, which identified a high level of antibiotic resistance in bacteria that can cause fatal bloodstream infections and an increasing level of resistance in bacteria that can cause common infections. The report echoes a wider concern about the need for the development of new antibiotics for newborn babies to address the up to 570,000 deaths and estimated three million cases of neonatal sepsis each year, many of which occur in the absence of effective antibiotics due to rising antimicrobial resistance.
