SARS-CoV-2 variants neutralized by camel nanobodies

Researchers from the US recently isolated two VHH nanobodies - 7A3 and 8A2 - from dromedary camels (Camelus dromedaries) using phage display. These nanobodies were found to have a high affinity for the spike RBD and broad neutralization abilities against SARS-CoV-2 and its variants.

The effect of mass vaccination on COVID-19 mortality in Israel

A team of scientists from Israel and the USA has recently examined the efficacy of coronavirus disease 2019 (COVID-19) vaccination in reducing the death risk among people aged 70 years and above. They observe that despite government-imparted relaxation on non-pharmaceutical control measures, the vaccine saved more lives than expected by individual-level vaccine efficacy.

Alteration in gut microbiome may lead to hyperinflammation in severe COVID-19

A team of international scientists has recently identified a distinct set of proinflammatory mediators and metabolites associated with the fatal consequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Moreover, they have established a link between gut microbiome alteration and hyper-inflammatory response in patients with severe COVID-19. The study is currently available on the bioRxiv* preprint server.

Emerging SARS-CoV-2 variant A.30 efficiently evades vaccine-induced immunity

A recent study published in the journal Cellular & Molecular Immunology shows that a new A.30 variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can evade vaccine-induced antibodies and might spread outside the lungs extraordinarily well, with important implications for our public health response.
