In June, South Sudan is expecting to begin the rollout of the preventive malaria intervention seasonal malaria chemoprevention (SMC), although there are concerns that high parasite resistance in eastern and southern African countries will limit its long-term efficacy. In June 2022, the World Health Organization (WHO) updated its recommendations that previously restricted SMC’s use to the Sahel region, where malaria transmission is highly seasonal, to encourage its use in other regions after pilot studies showed positive results in countries with high resistance, including South Sudan. Experts have emphasized the need for rigorous monitoring and evaluation to assess SMC’s efficacy in areas of high resistance and to detect any parasite resistance in the Sahel, as well as the development of alternative tools and drugs for malaria chemoprevention.Last week, the European Medicines Agency recommended authorization of GSK’s Arezvy vaccine for respiratory syncytial virus (RSV) in adults 60 years of age and older, which if approved, will be the world’s first available vaccine for RSV. Regulatory agencies in the United Kingdom and United States are expected to make decisions on GSK’s vaccine in the coming months. Pfizer and Moderna are also developing vaccines for the virus, with Pfizer’s candidate already having gained the backing of a panel of US Food and Drug Administration (FDA) advisors earlier this year.Bavarian Nordic, the maker of the Jynneos vaccine, which is approved by the FDA to protect against both smallpox and mpox, is planning to dramatically scale up production capacity for their vaccine. The company’s CEO connected the move to the rapid spread of mpox last year, which highlighted the need to be able to manufacture at a much greater scale than currently available: from tens of millions to hundreds of millions of doses. Bavarian Nordic plans to simplify its production process to facilitate partnerships with other manufacturers in order to have adequate production capacity for stockpiling and in case of a future emergency.

During the COVID-19 pandemic, the facility was established in response to global vaccine access inequity to pursue mRNA vaccines for COVID-19 and potentially other poverty-related diseases. South African biotech firm Afrigen Biologics and vaccine producer Biovac are working with the publicly available sequence of Moderna’s mRNA COVID-19 vaccine to create a similar vaccine candidate, which will be tested on humans early next year. The candidate will the first to be made based on a widely used vaccine (like Moderna’s) without the developer’s approval and assistance and the first mRNA vaccine designed, developed, and produced at lab scale on the African continent.The White House plans to nominate cancer surgeon Dr. Monica Bertagnolli to become the director of the US National Institutes of Health (NIH), succeeding Dr. Francis Collins, who stepped down in 2021. Dr. Bertagnolli has served as the director of the National Cancer Institute since last fall. If confirmed by the Senate, she will inherit COVID-19 pandemic-era challenges around increased scrutiny of the agency’s funding of virus research, including grants to EcoHealth Alliance, which studied coronaviruses in Wuhan, China.Two studies published last week found that repurposed drug combinations lowered the risk of severe COVID-19 in high-risk patients. Stanford University researchers looked at the combination of the antidepressant fluvoxamine and the corticosteroid budesonide among nonhospitalized adults with early symptomatic COVID-19 and at least one risk factor. A second team from Weill Cornell Medicine looked at the combination of the monoclonal antibodies amubarvimab and romlusevimab in nonhospitalized adult COVID-19 patients with high-risk factors. Using combinations of repurposed drugs to treat severe COVID-19 (if successful in further testing) could prove to be an important tool in reducing the burden of COVID-19 in low- and middle-income countries, where oral therapeutics for COVID-19 are largely unavailable.
