Pan-COVID-19 vaccine protects mice against SARS-CoV-2 variants

Researchers in the United States have identified short peptide sequences in the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that are immunogenic in a mouse model and may provide protection against viral variants.

Study reveals no negative effect of SARS-CoV-2 BNT162b2 vaccination on male fertility

Researchers analyzed the sperm parameters of males undergoing fertility treatment and found no effect from the BNT162b2 mRNA severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine.

Can the absence of evidence of in-school SARS-CoV-2 transmission be taken as evidence of absence?

Research by scientists at the University of Texas at Austin, the Santa Fe Institute, and Fractal Therapeutics suggests infection rates in the surrounding community are not a reliable measure for estimating the level of risk for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission in schools.

Researchers identify mechanism of platelet hyperactivation in COVID-19 patients

A recent study conducted at the University of Pennsylvania and the Children’s Hospital of Philadelphia, USA, has revealed the mechanism of platelet hyperactivation in critically ill coronavirus disease 2019 (COVID-19) patients.

What happens in the first few days of SARS-CoV-2 infection?

New research, published in PLOS Biology, has evaluated SARS-CoV-2 infection in primary cultures of well-differentiated cells to determine how the virus affects the body and how the infection starts. Answers to these questions are essential to forming a general understanding of viral pathogenesis, which helps us develop effective prevention and treatment strategies for COVID-19.

Can SARS-CoV-2’s impairment of endothelium cause vascular disease?

The study, published in the journal Circulation Research, suggests that COVID-19 is not only a respiratory disease but also a vascular disease. It highlights how the virus attacks the vascular system, causing endothelial impairment.

Moderna COVID-19 vaccine makes it on WHO Emergency Use Listing

Moderna has announced Emergency Use Listing granted by the World Health Organization for its COVID-19 mRNA vaccine.

COVID-19 in pregnancy does not significantly increase respiratory illness in newborns, says study

A new study published in the journal JAMA offers reassuring evidence that infants born to mothers with coronavirus disease 2019 (COVID-19), or even asymptomatic infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), have little increase in respiratory symptoms over babies born to uninfected mothers.

Could in vitro glycoengineering help produce better SARS-CoV-2 spike candidates for vaccine research?

A vexing problem in the development of vaccines has been the need to achieve the right glycosylation profile for the viral antigens. A new study, recently released as a preprint on the bioRxiv* server, shows how a sequential cell-free approach produced complex N-glycans from simpler types, in a one-pot reaction.

Rapid and sensitive SARS-CoV-2 detection from saliva using CRISPR

In a paper recently uploaded to the preprint server medRxiv by Edward Málaga Trillo et al. (April 29th, 2021), these methods are tested in combination with CRISPR-Cas detection in the field, demonstrating a sensitivity and specificity of 93.8% and 99%, respectively.

Evidence that elevated blood glucose is a significant risk factor for severe COVID-19

The literature analysis pointed to elevated blood glucose levels as a leading facilitator in the progression of COVID-19. Evidence linking elevated glucose to various steps in the life cycle of the virus and presentation of COVID-19 symptoms were also found.

SARS-CoV-2 study in human gut organoids

Most of the major life-threatening symptoms of COVID-19 disease are associated with the host's generation of an exacerbated pro-inflammatory immune response. Many studies have correlated the intensity of the immune response with the severity of disease.

Study shows a protective association between anticoagulants and COVID-19

In a new study, researchers investigated the association between the use of oral anticoagulants and warfarin in COVID-19 disease outcomes. They published their results in a paper on the medRxiv* preprint server.

Differential NK cell activity found to contribute to SARS-CoV-2 infection resistance

The COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has affected millions of people worldwide and is the leading cause of mortality in Brazil in 2020 as well as early 2021. Clinical manifestations of COVID-19 disease range from no symptoms and mild flu-like symptoms to severe cases leading to hospitalization and death.

Monoclonal antibody neutralizes all SARS-CoV-2 variants of concern

Researchers in Canada and the United States have identified a monoclonal antibody that potently neutralizes variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the ongoing coronavirus disease 2019 (COVIdD-19) pandemic.

Researchers demonstrate real-world effectiveness of Johnson & Johnson COVID-19 vaccine

Researchers in the United States and India have conducted a study demonstrating the real-world effectiveness of a single dose of Johnson & Johnson’s Ad26.COV2.S vaccine at preventing infection with severe acute respiratory syndrome coronavirus 2 – the agent that causes coronavirus disease 2019 (COVID-19).

SARS-CoV-2 antibodies are detectable up to a year after infection, finds study

A team of scientists from the United States has recently investigated the robustness and durability of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in coronavirus disease 2019 (COVID-19) patients. Their findings reveal that COVID-19 patients exhibit a strong anti-SARS-CoV-2 antibody response for up to 1 year and that the robustness of antibody response depends on the patient’s age and disease severity.
