The growing resistance of the gonorrhea bacteria to many classes of antibiotics has left only one remaining globally recommended treatment available as an option. Zoliflodacin, if approved, could not only help address those rising cases because studies have shown that it is active against multi-drug resistant gonorrhea strains, but the antibiotic will also simplify treatment because it is one pill rather than an injection and a pill like the current standard therapy.  New study shows how the Ebola virus infects cells Phys.org (11/1) Last week, the Coalition for Epidemic Preparedness Innovations (CEPI) and the University of Oxford announced the launch of a new project to develop prototype vaccines against an arenavirus called Junin virus, which causes Argentine hemorrhagic fever. The project is aimed at kickstarting the broader development of vaccines for arenaviruses, which include the virus that causes Lassa fever, one of CEPI’s priority pathogens. CEPI will invest $25 million in the development of early prototypes of viral vector and mRNA vaccines against the Junin virus, as well as the improvement of the ChAdOx viral vector technology, part of the broader partnership between CEPI and Oxford to support vaccine development for a variety of viral families with future epidemic or pandemic potential. In a recent study, researchers have identified a new molecule in cells that is necessary for the Ebola and Marburg viruses to infect and spread in the body and that is also involved in SARS-CoV-2 infections. This discovery could eventually lead to new antiviral drugs for Ebola and Marburg, among other viral infections. The molecular, CCZ1, is a protein that regulates the transport of other molecules by cells. Researchers from the Karolinska Institutet and Institute of Molecular Biotechnology used advanced stem cell libraries and lab-grown organs to study how viruses infect the human liver and blood vessels and ultimately demonstrate how CCZ1 operates as a key factor in their spread through the body.  CEPI, Oxford launch project to develop arenavirus vaccines CIDRAP (11/2), features CEPI

Moderna’s trial began last week, with Pfizer and BioNTech’s likely to start in the coming months as well. A combination vaccine for COVID-19 and influenza has the potential to greatly reduce the burden of these respiratory viruses on patients, providers, and health care systems, underscoring why these companies and the broader research community have placed a greater focus on combination vaccines coming out of the pandemic.At the annual meeting of the American Society of Tropical Medicine and Hygiene (ASTMH) last week, the World Health Organization reported the results of a major evaluation of a pilot rollout in three African countries of RTS,S, the first approved malaria vaccine, showing positive findings about the lives it has already saved. RTS,S cut deaths among young children by 13 percent over nearly four years and cut cases of severe malaria by 22 percent among kids young enough to have received a three-shot regimen. The RTS,S vaccine is notably not a perfect tool, given the limited durability of its protection and lower efficacy, but health experts say this data makes a strong case for broader rollout of RTS,S and the potential of integrating the second approved malaria vaccine, R21, into multipronged efforts to fight malaria.A research team at the Johns Hopkins Bloomberg School of Public Health has shown for the first time that human volunteers can be safely and effectively infected with Zika virus, which could benefit research efforts to gain a greater understanding of the disease and to develop vaccines and treatments to use against it, as none currently exist. This controlled human infection model is useful for research because during the 2015-2016 outbreak, researchers were unable to test experimental products in time before the epidemic subsided, and since, there have not been any large outbreaks. The new model is controversial but has been ruled by US regulators and the World Health Organization as safe and scientifically important.

At GHTC, we get to read stories every day about incredible innovations in global health. Most of the technologies we see are inventive, some are revolutionary, and a few are so unusual, one might think they were ripped from the pages of a science fiction novel. Now, we’re testing how well you know these global health technologies with our annual Halloween game: the TRICK or TREATment quiz.For each question, we will present a description of a global health technology. Choose TREATment if you believe this innovation exists. Choose TRICK if you think we are trying to pull one over on you and, instead, the product is still in development or is just a figment of our imagination.

Specifically, the awards will go to two intranasal vaccine candidates that are administered as sprays and one self-amplifying mRNA vaccine candidate that is administered as an injection; phase 2b clinical trials of those vaccine candidates could start as soon as this winter. Funding will also go to the development of vaccine patches, cold-chain sample management, genomic sequencing, and increased laboratory capacity.The Coalition for Epidemic Preparedness Innovations (CEPI) is leading an initiative with the biopharma data provider IQVIA aimed at enhancing global research capacity to advance the 100 Days Mission, which aims to be able to respond to the next Disease X (a future pathogen with pandemic potential) with medical countermeasures within 100 days of its identification. Under the initiative, IQVIA will provide tools and resources to support research preparedness in underserved regions during ‘peacetime’ (when there is no ongoing pandemic outbreak) and to support clinical trials during future outbreaks of diseases with pandemic potential. CEPI will fill in gaps to ensure high-quality data are generated during an outbreak response to inform further research.Last week, The Lancet and the Coalition for Preventing Pandemics at the Source announced that they have convened the Commission on Prevention of Viral Spillover, which will work to mobilize decision-makers to support research and policies to prevent future viral spillovers and pandemics following the COVID-19 pandemic, which was the fifth viral pandemic caused by a viral spillover in the last century. The commission, which includes 28 experts in a variety of fields from epidemiology to veterinary medicine to food systems management, will conduct original research and publish a comprehensive report within two to three years on recommendations to prevent such spillovers.
