Monkeypox investigation as new cluster sparks fears of possible mutation
The Telegraph (4/4)
French researchers are investigating after 59 percent of individuals in a new mpox outbreak cluster claim to be vaccinated, raising fears that the virus has mutated. 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.
Midge Medical, Institut Pasteur de Dakar partner for rapid Marburg virus test
360Dx (4/4)
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.
A new approach to a Covid-19 nasal vaccine shows early promise
CNN (4/3)
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.
