Horseshoe or Rhinopolus bats in Laos carry coronavirus species with a near-identical receptor binding domain to SARS-CoV-2, according to a paper posted on the preprint server Research Square by investigators from the Pasteur Institutes of Paris and Laos.

Trimers of nanobodies, a simpler form of antibody made by some animal species, were effective at preventing and treating COVID-19 in preclinical studies, researchers reported in the Sept. 22, 2021, issue of Nature Communications. The findings, along with others, could form the basis of an inhaled biologics treatment for COVID-19 and, ultimately, other respiratory diseases.

The COVID-19 pandemic is still swirling about, and rapid antigen tests are still playing a vital role in pushing back against the COVID-19 pandemic, and Australia’s TGA has responded with a guidance on when software used with rapid antigen tests qualifies as a regulated device. The TGA has classified such software as a class 3 device when used with a rapid antigen self-test, thus requiring a separate regulatory application before it can be eligible for entry in the Australian Register of Therapeutic Goods (ARTG).

LONDON – Researchers in the U.K. have applied the heft of national population-level databases to devise a new algorithm that predicts those people who are most at risk of hospitalization and death from COVID-19, despite having received two doses of vaccine.
