NIH-funded adjuvant improves the efficacy India's COVID-19 vaccine

An adjuvant developed with funding from the National Institutes of Health has contributed to the success of the highly efficacious COVAXIN COVID-19 vaccine, which roughly 25 million people have received to date in India and elsewhere.

Study shows SARS-CoV-2 breakthrough infections fewer among fully vaccinated

A team of researchers at Indiana University reports genomic evidence of breakthrough infections in fully vaccinated individuals. The study, posted to the pre-print server medRxiv*, suggests that fully vaccinated individuals, including those with asymptomatic infections, are less likely to serve as a source of infection for others.

Alpha (B.1.1.7) SARS-CoV-2 variant associated with more severe disease in hospitalized women

Researchers in the UK have conducted a study showing that infection with the B.1.1.7 (Alpha) lineage of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may be associated with an increased risk of death or intensive care unit (ITU) admission among women, compared with non-B.1.1.7 infection.

Widespread SARS-CoV-2 mutation escapes vaccine- and infection-induced CD8 T-cell responses

Researchers in the UK have warned that a widespread mutation that has arisen in the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) appears to escape recognition by CD8 T-cell responses in both convalescent patients and recipients of the current coronavirus disease 2019 (COVID-19) vaccines.

Researchers show how Covid-19 changes the size and stiffness of red and white blood cells

Using real-time deformability cytometry, researchers at the Max-Planck-Zentrum für Physik und Medizin in Erlangen were able to show for the first time: Covid-19 significantly changes the size and stiffness of red and white blood cells - sometimes over months.

Innovative corona test offers great potential for systematic testing

A new corona test developed at the University Hospital Bonn can analyze a large number of swabs simultaneously using sequencing technology and has a similarly high sensitivity as the common qPCR test.

More evidence that mixing COVID-19 vaccines may help elicit a robust immune response

Eight volunteers who received a complete dose or a single dose of an mRNA vaccine or the ChAdOx1 vaccine after a dose of a trial gorilla adenovirus vaccine showed a significantly high level of antibodies and T cell response against SARS-CoV-2.

Can COVID-19 waves be predicted using early warning signal indicators?

Researchers combined daily case data and a sequential analysis using the critical slowing down model to predict coronavirus disease 2019 (COVID-19) waves almost two weeks before their onset.

29 Jun 2021

Study offers more evidence that face masks can prevent SARS-CoV-2 transmission

A new study released as a preprint on the medRxiv* server suggests that the use of face masks, of various designs, successfully prevents SARS-CoV-2 transmission. This supports the continued implementation of mask policies in public places until herd immunity is achieved in the region involved.

How is Taiwan tackling its third wave of COVID-19?

The international community has been struggling to predict and contain successive waves of the COVID-19 pandemic, caused by the novel SARS-CoV-2 pathogen. The degree of success has varied between countries. In Taiwan, the use of contact tracing, with testing and isolation of confirmed cases, promises to end the ongoing third wave of the illness within two months. The strategy employed is described in a new preprint available on the medRxiv* server.

The technology behind face masks that can diagnose COVID-19

Researchers have recently incorporated technology into standard face masks to detect the presence of SARS-CoV-2.

How does dexamethasone therapy work in severe COVID-19?

The possible mechanisms that result in dexamethasone being an effective drug against severe SARS-CoV-2 infection are investigated in a new study. The paper’s authors advance the hypothesis that SARS-CoV-2 infection induces cell-specific insensitivity to glucocorticoids, possibly as an unintentional result of the viral replication cycle.

Cationic peptides inhibit SARS-CoV-2 cell entry

In a paper recently published in Pathogens, in silico affinity studies by researchers at the University of Illinois, USA, reveal several potential peptide binding sites required for HS-spike protein and ACE2-spike protein bond formation, and synthesis of suitable peptide inhibitors reveals impaired SARS-CoV-2 cell entry.

Nanotechnology and the fight against COVID-19

In a review paper published in the open-access MDPI journal Viruses, a team of researchers explored the potential of nanotechnology to alleviate the current and future coronavirus burden. The team focused on its potential role in the detection, diagnosis, protection, and treatment of SARS-CoV-2 infection.

Without enough boots on the ground, California’s vaccination efforts falter

Gov. Gavin Newsom routinely boasts that California has "one of the highest vaccination rates in the United States of America."

Analysis: Why we’ll likely never know whether a covid lab leak happened in China

Early in this century, post-SARS, and in a period when China started allowing more students and scientists to study abroad, collaboration and exchange between American and Chinese scientists blossomed.

Clinical observations show acute myocarditis developed after mRNA COVID-19 vaccination

Four patients suffering from acute myocarditis after mRNA COVID-19 vaccination suggests that further investigation is needed.

Study explores structure, activity, and inhibition of TMPRSS2 implicated in SARS-CoV-2 activation

Researchers from Canada recently presented an efficient strategy for recombinant production of enzymatically active TMPRSS2 ectodomain, enabling enzymatic characterization and the 1.95 Å X-ray crystal structure. Their work is published on the bioRxiv* preprint server while awaiting peer-review.

New spider web mechanism kills pathogens and virus responsible for COVID-19

Immunologists at McMaster University have discovered a previously unknown mechanism which acts like a spider web, trapping and killing pathogens such as influenza or SARS-CoV-2, the virus responsible for COVID-19.

Tackling emerging SARS-CoV-2 variants

An international team of authors has published a special report in The New England Journal of Medicine titled 'SARS-CoV-2 Variants and Vaccines’, which presents global strategies for the possible escape from vaccine-elicited immunity.
