Those trials should get underway soon, said WHO officials, as four or five of the 28 potential candidates already have doses ready. In the meantime, contact tracing, isolation, and supportive care are being used to prevent transmission in the countries. A lack of laboratory capacity in Equatorial Guinea has so far prevented the timely identification of cases, but the Africa Centres for Disease Control and Prevention is working to provide technical support, as well as build infrastructure and capacity to improve testing, which will be important in upcoming trials.Last week, the US Centers for Disease Control and Prevention (CDC) warned about the recent, rapid spread of the drug-resistant fungus Candida auris, or C. auris, in health care facilities and highlighted the serious risk the fungus poses to immunocompromised individuals. C. auris is resistant to typical antifungal treatments, and developing a vaccine for the fungus would likely take many years. There are currently no approved vaccines for any form of fungal infections. One vaccine candidate, being developed with support from the US National Institutes of Health, is designed to be cross-protective against several fungal pathogens, potentially including C. auris, although a phase 1 clinical trial is over a year away.Executives at three of the world’s leading flu vaccine manufacturers—GSK, Moderna, and CSL Sequiris— have said that they are preparing the capacity to develop hundreds of millions of avian flu shots within months if a new strain of avian flu jumps to humans. The companies are already or will soon begin testing sample human vaccines that match the subtype currently circulating among birds and mammals. Sanofi has also expressed its readiness to begin production, alongside its stock of existing H5N1 vaccines. However, there is concern about how to ensure equitable global access to such vaccines in the case of an outbreak, given a substantial portion of doses are already reserved for wealthy countries through preexisting preparedness contracts.

The treatment was tested for prevention and treatment in mice and for prevention in monkeys. No treatment exists for dengue, which has four different strains, and the two available vaccines for the disease have not yet been approved universally, highlighting the great potential of this new treatment in reducing disease burden. Further research is needed to find out whether the treatment could produce vulnerability to more serious reinfection and to test the compound in humans.Last week, the World Health Organization (WHO) recommended the use of bednets treated with new insecticides in areas where there is mosquito resistance to pyrethroid, which has historically been used to treat bednets. WHO now recommends combining pyrethroid with an additional chemical—either the insect growth regulator pyriproxyfen or the insecticide chlorfenapyr. The recommendations are based on large-scale trials done by the London School of Hygiene & Tropical Medicine in Tanzania and Benin. Researchers say the rollout of the new bednets could happen as early as the next few months and should take place in concert with the development of a comprehensive long-term plan to manage and prevent future resistance.Mobile vaccine production units, made by German pharmaceutical company BioNTech, recently arrived in Rwanda as part of a larger initiative to boost mRNA vaccine manufacturing on the African continent. The facility, which will hopefully start producing doses in around a year, will be able to manufacture up to 100 million mRNA vaccines a year for African Union countries, as well as potentially innovate treatments for diseases like HIV/AIDS, tuberculosis, and malaria, which are among the leading causes of death on the continent. There are further deliveries of these mobile production units planned for South Africa and Senegal.
