TriSb92 as a potential inhibitor against SARS-CoV-2 variants including Omicron

New findings indicate that TriSb92 is a potent inhibitor of SARS-CoV-2 infection targeting a conserved site in the RBD of the spike, which is insensitive for immune escape mutations found in the relevant variants of concern, including Omicron

Pre-existing immunity against influenza can lower SARS-CoV-2 infection burden and spread

A recent study by a team of European researchers demonstrated how antibodies induced by currently circulating influenza A H1N1 strains can cross-react with the important part of the SARS-CoV-2 spike glycoprotein that interacts with the human cell receptor. Their paper is currently available on the medRxiv* preprint server while it undergoes peer review.
