Rosin soap as a potential SARS-CoV-2 disinfectant

In a research paper recently uploaded to the preprint server bioRxiv* by Bell et al. (July 19th, 2021), the potential of rosin soap as a virucide is investigated, finding a ten-thousand-fold drop in infectivity against enveloped viruses such as influenza and SARS-CoV-2 in particular.

SARS-CoV-2 delta variant associated with several vaccine breakthrough cases in Houston

Their findings reveal that about 58% of all new coronavirus disease 2019 (COVID-19) cases are due to the delta variant and that the prevalence of vaccine breakthrough cases associated with the variant is as high as 20%. The study is currently available on the medRxiv* preprint server while awaiting peer review.

Advantages and challenges of intranasal vaccines to fight against COVID-19 infections

There are many reasons that an intranasal vaccine against the SARS-CoV-2 virus would be helpful in the fight against COVID-19 infections, University of Alabama at Birmingham immunologists Fran Lund, Ph.D., and Troy Randall, Ph.D., write in a viewpoint article in the journal Science.

Blunted antiviral responses in the nasopharynx may underlie severe COVID-19

The body's first encounter with SARS-CoV-2, the virus behind COVID-19, happens in the nose and throat, or nasopharynx. A new study in the journal Cell suggests that the first responses in this battleground help determine who will develop severe disease and who will get through with mild or no illness.
