Researchers in Canada explore risks of SARS-CoV-2 transmission in retirement homes

Researchers at the McMaster University, Canada, have found that the higher the population in retirement homes, the higher the risk of COVID-19 outbreaks. Moreover, they found that retirement homes in a community with a higher ethnic concentration are also more likely to face COVID-19 outbreaks.

UK researchers examine university students behavior amid COVID-19 prevention measures

A team of UK-based researchers at the University of Bristol and the University of Exeter found that university students report fewer daily contacts amid the coronavirus pandemic. However, most of these contacts were those not affiliated with the university, indicating potential transmission to other people other than students and staff.

Researchers test commercial assays to detect SARS-CoV-2 antibodies six months after infection

Researchers at the Hospices Civils de Lyon (HCL) in France found that people infected with SARS-CoV-2 can develop antibodies that persist for up to six months. After testing commercial assays to detect antibodies, the Wantai antibody assay has a positivity rate of 100%.

COVID-19 vaccination may potentially cut hospitalizations, deaths by 60% in Ontario, Canada

A new study suggests an impact of the COVID-19 vaccine on SARS-CoV-2 attack rate, and hospitalizations, even with no protection against infection.

Less sensitive rapid tests may miss asymptomatic/presymptomatic SARS-CoV-2 infection

The rapid transmissibility of SARS-CoV-2 has posed a significant challenge to COVID-19 containment measures.

Epitope “megapools” could help determine role T cell immunity plays in COVID-19

Researchers in the United States and Australia have conducted a comprehensive analysis of the epitope recognition patterns associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in humans.

Prior T cell immunity to SARS-CoV-2 unlikely to be the result of seasonal coronavirus infection

Scientists have suggested that a proportion of the population have pre-existing immunity to COVID-19 because of T cells primed against SARS-CoV-2 antigens.

D614G mutation promotes lysosomal trafficking of SARS-CoV-2 spike protein

In the current COVID-19 pandemic, SARS-CoV-2 has led to millions of infections worldwide, with over 1.5 million deaths.

Recovered COVID-19 patients exhibit persistent cellular immunity

Researchers at The Rockefeller University in New York have conducted a study showing that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – triggers persistent T cell responses that last for at least six months.

SARS-CoV-2 Nsp3 protease activity and nanobody inhibitor development

A new study published in the pre-print server bioRxiv* explores the viral enzyme PLpro, encoded in the nonstructural protein nsp3, and its inhibitors. T

Case study suggests kindergartens are not SARS-CoV-2 super-spreaders

A new study by researchers at the Institute of Tropical Medicine and International Health at the Charite Universitaetsmedizin Berlin found that kindergartens are not silent transmission reservoirs.

Structural inequalities increase risk of SARS-CoV-2 infection and mortality, study finds

A new study by researchers at Harvard found that people in less privileged neighborhoods are at a higher risk of being infected with SARS-CoV-2 and of more severe COVID-19.

Researchers investigate whether tailored online exercise benefits ‘long Covid’ patients

Researchers at the University of Warwick and University Hospitals Coventry and Warwickshire NHS Trust are to investigate whether a tailored online exercise and support programme would benefit those experiencing long-term symptoms of Covid-19 - what has been dubbed 'long Covid'.

New analysis method could pave the way for important breakthroughs in immunotherapy

In a new study, researchers at Uppsala University have been able to show differences in how Rituximab, a monoclonal antibody drug, interacts with the blood of healthy individuals compared to patients with chronic lymphatic leukemia. This has awakened hopes that this analysis method could pave the way for important breakthroughs in immunotherapy research and treatment.
