Bavarian Nordic’s vaccine for smallpox was deployed in the United States and Europe under emergency authorizations and recommended by WHO primarily for post-exposure during the mpox emergency, although the limited available stock that was already earmarked for wealthy countries created access challenges in low- and middle-income countries. Randomized control trials planned in endemic countries will provide more essential data about the efficacy of the vaccine against mpox. Additional data is also needed to fully understand how the strain of the virus evolved to sustain prolonged transmission between humans.Last week, the US$30 million Human Pangenome project, launched in 2019 and funded by the US National Human Genome Research Institute, published the first phase of the first human pangenome, which aims to be a genome that is more representative of the diversity of DNA in humans around the world. The genome could be an important guide for researchers building genetic tests and looking for new drug targets. This initiative addresses diversity gaps in the first reference genome, released in 2001, which have undermined the ability to develop tests that work across diverse populations.A new global research consortium organized by the Centres for Antimicrobial Optimisation Network aims to fight antimicrobial resistance by improving clinical use of antimicrobials and improving practices and guidelines for prescribers, users, and policymakers. Research hubs in Kampala, Cape Town, São Paulo, Liverpool, and London—where there is a high burden of drug-resistant infections and where there are communities highly affected by the burden of infectious disease—will generate essential data on the optimal use of antibiotics. Researchers hope this will in turn lead to more effective treatment and prevention of bacterial infections in the face of rising antimicrobial resistance worldwide.

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.

The investigation will look at various questions, including when the individuals were vaccinated and at what dose, as well as whether they share a common characteristic like having HIV that could impact the effectiveness of the vaccine. If other possibilities are ruled out, French health authorities will start looking at the possibility of a mutation in the virus. The vaccine, Imvanex or Jynneos, is a third-generation smallpox vaccine. There is no specific vaccine for mpox, and this investigation could yield important data about the real-life efficacy of this vaccine for the virus, which is expected to remain a public health issue.This week, German diagnostics startup Midge Medical announced a partnership with the Institut Pasteur de Dakar to offer a rapid molecular diagnostic test for Marburg virus for field testing on the African continent. The collaboration started with a request from the Institut to adapt the startup’s Minoo system, a portable, battery-operated, isothermal amplification instrument with smartphone connectivity enabling data analysis and readout of results, which was previously used for COVID-19 testing. Midge Medical said they integrated the Marburg virus test into the Minoo platform within a month and delivered a prototype assay and provided training to staff at the Institut for field testing, where it has been favorably received.German scientists have reported promising results for a nasal vaccine for COVID-19 tested in hamsters. While this vaccine is not yet close to rollout, other nasal vaccines have been in use in China and India since last fall (although studies about their effectiveness has not yet been published) and at least four other nasal vaccines for COVID-19 are in late-stage clinical trials. While strong data to back up these vaccines is still needed, the hope is that these next-generation vaccines could better prevent people from getting sick and spreading infection by blocking the virus at the point of entry in the nose and throat where it first gains a foothold.

The agency will continue reviewing tests that have already been submitted for authorization and is expected to review only some additional tests from experienced developers that use innovative technological approaches, fill a gap in need, or demonstrate potential for wide public health benefits. Instead, the agency is encouraging most developers to submit their tests through different review processes. Despite the end of the national emergency declaration for the COVID-19 pandemic on May 11, the 440 EUAs already granted will remain in effect as long as a separate agency-level EUA declaration determined by FDA continues.The World Health Organization (WHO) convened an emergency meeting of the Marburg virus vaccine consortium following the confirmation of the first-ever Marburg outbreak in Equatorial Guinea. During the meeting, five vaccine developers shared updates on their vaccine candidates for the disease. WHO is taking steps toward pursuing a real-time clinical trial for some of the candidates in alignment with the already-approved WHO clinical trial protocol for Marburg vaccines (which needs to be adapted to the country context) and in consultation with country officials. Sabin Vaccine Institute and Janssen’s candidates are in phase 1 clinical trials, while IAVI, Public Health Vaccines, and Auro Vaccines’ candidates are still in the pre-clinical development stage.A new study published last week found that a drug tested in mice could potentially be used as a birth control option for men. If successful in further trials, the drug would work as an on-demand contraceptive compared to other male contraceptives in the pipeline, like daily pills and gels, that researchers say are more complicated, time-consuming, and long-lasting. The drug works by preventing a molecular action from turning sperm “on” and activating them to pursue an egg. The researchers have founded a new company to move forward development of the drug but note it will likely be years before it is ready for testing in men.
