Optimizing allocation of future COVID-19 vaccine can double effectiveness

In anticipation of coronavirus disease (COVID-19) vaccine deployment, the Australian and US researchers utilized an age-structured mathematical model to appraise the potential benefits of optimizing age-specific dose allocation for suppressing SARS-CoV-2 transmission – and reaffirmed the notion that vaccination alone may be inadequate to achieve herd immunity in some settings. The study is currently available on the medRxiv* preprint server.

Nasal spray COVID-19 vaccine shows promising results in mice

With promising vaccines comes a new candidate that has shown potent pre-clinical immune responses. The vaccine, developed by scientists at the University of Alabama at Birmingham (UAB), induced a potent T-cell response at the mucus layer of the lungs, including killer CD8+ T-cells, which can recognize and kill virally infected cells.

SARS-CoV-2 can survive for 4 weeks on glass, money and metal

Published in the Virology Journal, the study shows that the virus can stay infectious for more extended periods on surfaces such as phone screens, stainless steel, and banknotes than previously thought.

COVID-19 survivors may have protective antibodies for 4 months

The study, published in the journal Science Immunology, highlights the body's immune response against COVID-19. Also, it offers hope that people who are infected with the SARS-CoV-2 virus will develop lasting protection against reinfection.

Cloth masks should be machine washed daily during COVID-19, study says

A team of researchers reports that cloth masks effectively protect against infection if they are washed every day. The researchers recommend daily washing of cloth masks at high temperatures to reduce the likelihood of contamination and transmission of viruses such as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of the coronavirus disease (COVID-19).

Elevated plasma ACE2 activity persists months after SARS-CoV-2 infection

Recently, researchers from the University of Melbourne and Immune Therapies Group, Burnet Institute, Melbourne, reported that downregulation of cardiac ACE2 is linked to increased plasma ACE2 activity. This study is summarized in a preprint paper published in medRxiv.

Temporal predictors of SARS-CoV-2 antibodies

Researchers in a recent paper published as a preprint on the preprint medRxiv, study the clinical factors, the laboratory assays to streamline plasma donor selection, and the durability of nAb responses in adults.

New study reports on extremely potent human monoclonal antibodies for SARS-CoV-2

Researchers have recovered and identified the various types of neutralizing antibodies for SARS-CoV-2 from convalescent COVID-19 patients. Of these, they identified three that are extremely potent and could be used to develop treatment therapies.

Vaccines likely to be effective against SARS-CoV-2 D614G mutation

The emergence of the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mutation D614G has raised many questions, including whether it will cause the virus to become resistant to the vaccines produced against earlier versions of the virus. A new study published in the journal npj Vaccines in October 2020 shows that this may be an unfounded fear.

Rapid and sensitive detection of SARS-CoV-2 with functionalized magnetic nanoparticles

A recent study published on the preprint server arXiv in October 2020 shows the potential for using functionalized magnetic nanoparticles to detect the presence of the virus in a sample.

Analysis of existing comorbidities and COVID-19 mortality

As the COVID-19 pandemic continues to spread, and research related to potential risk factors for COVID-19 mortality continues, it is becoming clear that individuals with underlying comorbidities have a greater risk of death from COVID-19. The exact contribution of different comorbidities is unclear, however. Now, a new study published in the journal PLOS ONE dissects this topic and may help to quantify the risk posed by specific conditions and offer help with the prognosis.

Pathways contributing to hypercoagulability in severe SARS‐CoV‐2 patients

In a study by researchers explored the possible mechanisms of the clotting disorder, focusing on the role of hypoxia-related activation of coagulation factors; cytokine storm, activation of neutrophils, and the release of neutrophil extracellular traps.

Fetal brain models could predict neurodevelopmental outcomes of COVID-19 exposure

Researchers in the United States and Sweden have created personalized models of fetal brain microglia to investigate the effects of maternal infection on the developing brain, including infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Exciting findings on CD8 T cell response in recovered COVID patients

An international team of scientists has identified novel T cell-recognized epitopes spanning different proteins of severe acute respiratory syndrome coronavirus 2 in COVID-19 recovered patients. The scientists have also revealed phenotypical characteristics of the T cell population.

86 percent of the UK's COVID-19 patients have no symptoms

Many people who contract the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes the coronavirus disease (COVID-19), develop only mild and moderate symptoms. A small fraction of those infected develop severe symptoms, which usually occur in people who are at higher risk due to comorbidities.

Clear and unequivocal evidence we should washing our hands during COVID-19

The study shows that Americans are washing their hands much more they did before the coronavirus pandemic. However, the groups who are less likely to remember to wash their hands on multiple occasions were white people, men, and those between the ages of 18 and 24.

Mass production of SARS-CoV-2 ORF8 protein using a chemical-inducible system in tobacco BY-2 cells

Researchers from the Japan Advanced Institute of Science and Technology (JAIST) and Ishikawa Prefectural University, Japan, recently attempted to synthesize the ORF8 protein with the help of a chemical-inducible protein production system using tobacco BY-2 cells. This study has been published demonstrated in the preprint server, bioRxiv.

SARS-CoV-2 survives on human skin for 9 hours

Japanese researchers have now studied the survival possibilities of the flu virus and the SARS-CoV-2 on human skin. Their study titled, "Survival of SARS-CoV-2 and influenza virus on the human skin: Importance of hand hygiene in COVID-19," was published in the latest issue of the journal Clinical Infectious Diseases.
