Elucidating the natural spillover theory on the SARS-CoV-2 emergence

To determine whether SARS-CoV-2 resulted from a natural spillover into humans, researchers discuss the veracity of early SARS-CoV-2 lineages.

Prevalence of adaptive and prolonged infections’ mutations in receptor-binding domain of SARS-CoV-2 spike protein

A new study used the available nucleotide sequence data on the NCBI COVID-19 database and estimated the global prevalence of adaptive and prolonged infections' mutations in the RBD of the S protein.

Antibody kinetics after natural SARS-CoV-2 infection and COVID-19 vaccination in Hispanic/Latino population

A new study addressing this issue has been published in Viruses that shows that functional neutralizing antibody tests are more relevant indicators than the presence or absence of binding antibodies.

Difficulties of stability and storage of mRNA COVID-19 vaccines

Two researchers have collaborated to review the difficulties faced in storing and transporting these vaccines in a manner that will keep them stable.

Key lessons from COVID-19 pandemic for scientific and clinical communities

In a paper published in the journal Cell, researchers have investigated and criticized clinical care management and drug administration within the pandemic.

Antiviral activity of wheat germ Agglutinin against SARS-CoV-2

A new study reports the antiviral activity of WGA against SARS-CoV-2 and its two Variants of Concern - Alpha and Beta.

Vaccination reduces risk of hospitalization from all SARS-CoV-2 variants

The findings reveal that patients infected with alpha, beta, gamma, and delta variants have a higher risk of hospitalization than those infected with the original viral strain that emerged in Wuhan, China, in late December 2019. The study is currently available on the medRxiv* preprint server while awaiting peer review.

Using a new public antibody to understand SARS-CoV-2 neutralization

SARS-CoV-2 infects host cells by binding to the angiotensin convertase 2 receptor (ACE2) on the cell surface through its trimeric spike (S) protein. SARS-CoV enters host human cells through endosomes, while SARS-CoV-2 enters through the cell surface and endosomes. The present study published in the journal “Cell Reports” aimed to understand the mechanisms of SARS-CoV-2 antibody neutralization to facilitate the development of therapeutic interventions for COVID-19.

REGEN-COV shown to reduce risk of COVID-19–related hospitalization or death from any cause

The phase 1-2 clinical trials conducted using REGEN-COV had shown promising therapeutic benefits in COVID-19 outpatients. Its effect was further investigated in the present phase 3 clinical trial, the findings of which have been published in the "The New England Journal of Medicine".

Machine learning predicts hospital-onset COVID-19 infections using patient contact networks

Researchers from the UK recently developed a real-time machine learning framework that uses dynamic patient contact networks to predict hospital-onset COVID-19 infections (HOCIs) at the patient level. They then tested and validated the framework on international multi-site datasets across various epidemic and endemic periods. This study can be found on the medRxiv* preprint server.

Immune response to SARS-CoV-2 variants of concern after natural infection or vaccination

A recent review paper published in the MDPI's journal Viruses highlights how available vaccines may be effective in protecting individuals against severe forms of coronavirus disease 2019 (COVID-19), but the protection against infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its transmission to others may be reduced – with consequences for community protection and herd immunity.
