Striking CryoEM image of SARS-CoV-2

A new study by researchers from the UK and Germany and published on the preprint server bioRxiv in June 2020 reports the results of a detailed study of the S protein on the intact virus, using cryoelectron microscopy (cryoEM) and tomography. This could help understand the conformation of the S protein on the virion and how it interacts with neutralizing antibodies.

Genomics used to trace origin of SARS-CoV-2 in Canada

A new study published in June 2020 on the preprint server bioRxiv discusses the use of phylogenetic analysis to trace the origin of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and its spread into and then within Canada. The study findings may help optimize public health policies in the case of future outbreaks.

Antibodies against prevalent endemic human coronaviruses may provide cross-protection to SARS-CoV-2

Researchers from Qatar have demonstrated that antibody repertoires against endemic human coronaviruses are qualitatively different in children when compared to the general adult population, as well as healthy adult blood bank donors – and they may also provide cross-protection against epidemic/pandemic strains.

Pangolin version of SARS-CoV-2 can cause COVID-19-like illness

The results of a recent multinational research endeavor, currently available on the bioRxiv preprint server, display the biological framework of SARS-CoV-2-related coronavirus in pangolins and reveal striking similarities to coronavirus disease (COVID-19) in humans, but also show that it can be transmitted vertically to the fetus.

Single-dose Israeli vaccine candidate protective against SARS-CoV-2

Now, a new Israeli study published on the preprint server bioRxiv in June 2020 reports a new recombinant vaccine expressing the S or spike protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to be highly protective with a single dose in an animal model. This could be a gamechanger in the fight to contain the outbreak.

Reassuring news on the Oxford vaccine (AZD1222) against SARS-CoV-2

A new paper from the UK vaccine research group, currently available on the bioRxiv preprint server, reveals that a single dose of ChAdOx1 nCoV-19 (AZD1222) can induce antigen-specific antibody and T cells responses against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and a booster shot additionally enhances antibody production with an increase in neutralizing titers – particularly in pigs.

Novel SARS-CoV-2 antibody cocktail impeccably mimics human antibody response

By using both humanized mice and convalescent patients, the researchers from the US and Singapore successfully generated non-competing and highly potent monoclonal antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein that could potentially be combined to form antibody cocktails. Their groundbreaking paper is published in the leading research journal Science.
