Research shows rapid antigen tests can detect SARS-CoV-2 variants, including Omicron

Researchers determined the analytical sensitivity of a CE-marked fast antigen with the SARS-CoV-2 Omicron, Delta, Alpha, and Gamma variants.

Study identifies drugs that could help combat mortality in patients with COVID-19

Inflammation is a defense mechanism of the body to fight pathogens. However, when it is widespread and excessive, it can aggravate the pathology and even cause death.

Yellow fever vaccine-vectored YF-S0 as a potent COVID-19 vaccine candidate

In a new study, a team of researchers developed YF-S0, an exceptionally potent COVID-19 vaccine candidate using live-attenuated yellow fever vaccine YF17D as a vector.

Study assesses the antibody response to additional dose of COVID-19 vaccine in transplant recipients

A study has begun to assess the antibody response to an additional dose of a COVID-19 mRNA vaccine in kidney and liver transplant recipients, either alone or with a concurrent reduction in immunosuppressive medication.

Three exposures to SARS-CoV-2 spike protein can induce robust neutralizing antibodies against variants

In a new study, scientists revealed that three consecutive exposures SARS-CoV-2 spike protein through infection, vaccination, or both can induce strong neutralizing antibodies against a wide variety of viral variants, including omicron.

It’s Day 6 of covid, and a rapid antigen test comes back positive. stay home, say virologists.

What does it mean if a person's rapid antigen test result comes back positive after five days of isolation due to covid-19? According to the experts, that person is most likely still carrying a viral load high enough to infect others.

In California nursing homes, omicron is bad, but so is the isolation

Dina Halperin had been cooped up alone for three weeks in her nursing home room after her two unvaccinated roommates were moved out at the onset of the omicron surge. "I'm frustrated," she said, "and so many of the nursing staff are burned out or just plain tired."

Accurate prediction of COVID-19 outbreaks using location data from mobile devices

Researchers at the Yale School of Public Health were able to accurately predict outbreaks of COVID-19 in Connecticut municipalities using anonymous location information from mobile devices, according to a new study published in Science Advances.

Evaluating clinical outcomes and viral loads of SARS-CoV-2 Delta and Omicron infections

The current study showed a marked decrease in disease severity with Omicron compared to the Delta variant.

Estimating the impending endemic seasonality of SARS-CoV-2 in global population centers

A new study uses long-term data on the incidence of circulating coronaviruses and estimates the endemic seasonality of SARS-CoV-2 in global population centers.

Nucleocapsid antigen found to be a sensitive biomarker for acute COVID-19 infection

In a new study, researchers found that nucleocapsid antigen in the blood (antigenemia) is a sensitive and specific biomarker for acute coronavirus disease 2019 infection.

Prion-like domains in SARS-CoV-2 RBD and ACE2 play important functional roles in viral adhesion and entry

Scientists have recently detected and analyzed viral PrDs in the S protein of SARS-CoV-2, which are the novel regulators of virion assembly.

Binding and conformational properties of the SARS-CoV spike protein and hACE2 complex

A new paper in the journal Molecules describes this in molecular terms, comparing SARS-CoV-2 with an earlier highly pathogenic coronavirus, SARS-CoV.

A substrate envelope approach to examine drug resistance potential of SARS-CoV-2 Mpro

A team of scientists from the United States has recently defined the substrate envelop of the main protease of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The study is currently available on the bioRxiv* preprint server while awaiting peer review.

31 Jan 2022

Vaccine-induced immunological memory is similar for Omicron and Delta SARS-CoV-2 variants

A new study by Norwegian researchers suggests that vaccine-induced immunological memory and the activation of recall responses in the body yields similar coverage for Omicron and Delta variants of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The paper is currently available on the medRxiv* preprint server while it undergoes peer review.

Research shows minks mimic severe COVID-19 symptoms, including ARDS

Minks may be a suitable animal model for testing severe COVID-19 infections, finds a recent bioRxiv* preprint study. While mice and ferrets are used in preclinical severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), there is currently no model specific to severe disease.
