Could novel biosensors facilitate SARS-CoV-2 antiviral drug research?

An intriguing new study presents a novel approach to biosensor-based evaluation of promising drugs that could inhibit the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) via its 3C-like protease (3CLpro), a viral protease.

Public and private SARS-CoV-2 T cell receptors may be crucial for pan-coronavirus vaccines

Researchers have just established a structural basis for two spike glycoprotein epitopes of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that are restricted to human leukocyte antigen (HLA) A2 molecules. More specifically, they are involved in the presentation of antigenic peptides to specific T lymphocytes and recognized by public and private T cell receptors. The research is currently available on the bioRxiv* preprint server.

Study reveals cellular basis of antigen-specific response to Pfizer-BioNTech’s COVID-19 vaccine

Researchers in the United States have provided important insights into the antigen-specific cellular response and evolving humoral (antibody) response to messenger RNA- (mRNA) based vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

99% of COVID-19 deaths in Italy occur among those not fully vaccinated

In a new report out of Italy, health officials reported that almost 99 percent of people who have died from COVID-19 since February 2021 were not fully vaccinated. The report released by the National Health Institute (ISS) showed that the few fully vaccinated people who died of COVID-19 were also older than those who died without complete COVID-19 vaccine doses.

Prior SARS-CoV-2 infection enhances effectiveness of Pfizer-BioNTech vaccine

A study conducted by researchers in Qatar has found that Pfizer-BioNTech’s coronavirus disease 2019 (COVID-19) vaccine was more protective against infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among individuals who had previously been infected with the virus than among those who had not.

Prevention of SARS-CoV-2 virus spread through aerosols

As the development of the COVID-19 pandemic to date has shown: aerosols contribute significantly to the occurrence of infection - and combating them can significantly reduce a resurgence of infection levels.
