Lassa fever is recognized by the World Health Organization (WHO) as a priority pathogen requiring accelerated research and causes an estimated 5,000 deaths each year, with the disease primarily affecting West Africa. There are no approved vaccines for Lassa currently. The hope is that this trial, which is the most advanced Lassa vaccine trial to date, will lead to the availability of a vaccine candidate for evaluation and use in future Lassa outbreaks and eventually an approved vaccine for routine immunization, as well as foster sustainable in-country research capacity and partnerships through engagement with Nigerian partners.Last week, FIND and LifeArc announced a new project in Kenya aimed at improving the detection and treatment of visceral leishmaniasis, a neglected tropical disease that mainly affects children and is fatal in more than 95 percent of cases if untreated. The project, which will run from 2024 to 2027, aims to increase early diagnosis and treatment to prevent disability and death from the disease in part by accelerating the development of new and improved diagnostic tests that are more sensitive than those currently available. The project will also build on ongoing efforts to improve community awareness, boost local and national testing capacity, and strengthen overall health system capacity.Last week, Cepheid announced that its point-of-care HIV test has received prequalification status from WHO. The decision will lead to the inclusion of the company’s HIV-1 PCR assay with extended coverage on a list of tests that meet WHO’s standards for global use, boosting access in low- and middle-income countries without designated or stringent regulatory authorities. The test can be used to detect HIV infection in infants and people who were recently infected and provides rapid results, enabling improved linkage to further care and treatment initiation.

The second-generation adjuvanted inactivated vaccine candidate, VLA1601, will be tested in 150 adult participants in the United States, with the first topline data from the trial expected as soon as early next year.  Numerous outbreaks of Zika have occurred around the world, but the virus is currently circulating in Mexico, Central and South America, the Caribbean region, and some areas of the continental United States.Moderna’s next-generation mRNA vaccine for COVID-19 elicited a higher immune response against most strains of omicron BA.4/BA.5 and the original virus than the company’s currently licensed vaccine and has a similar safety profile in Phase 3 trial. The vaccine candidate, mRNA-1283, demonstrated the highest benefits in patients over 65, who are at risk of more severe disease. The trial included over 11,000 patients from across the United States, the United Kingdom, and Canada. These results also point to the future promise of the company’s combination mRNA vaccines for COVID-19 and influenza, which are also currently in development and previously demonstrated a similar immune response to the company’s vaccines for COVID-19.The US Food and Drug Administration (FDA) recently announced the approval of Roche’s Cobas malaria test for screening blood, organ, and tissue donors, which could help reduce the risk of transfusion-transmitted malaria. The test is designed to qualitatively detect in whole-blood samples Plasmodium DNA and RNA from the five main species of Plasmodium parasite species known to cause human infection: P. falciparum, P. malariae, P. vivax, P. ovale, and P. knowlesi. Roche’s technology is now the first FDA-licensed test for screening blood donors for malaria.
