Study shows mRNA booster dose eliminates immune escape observed with SARS-CoV-2 Omicron

Researchers examined total and neutralizing antibodies to the spike protein of SARS-CoV-2, and neutralizing antibodies against Washington-1 (WA-1) and variants of concern (VOC) including Beta, Delta, and Omicron in a longitudinal cohort.

Study highlights importance of immunizing and boosting PAD syndromes patients with SARS-CoV-2 mRNA vaccines

A new study posted to the medRxiv* preprint server has evaluated the effect of mRNA-based COVID-19 vaccination and boosting strategy on serum antibody responses in PAD patients against the original SARS-CoV-2 strain and circulating variants.

Preliminary study assesses durability of NAb titers against Omicron after mRNA-1273 booster

Researchers from Moderna, the developers of one key vaccine, have been investigating its ability to protect against the Omicron variant.

Vaccination as a condition of deployment for health, social care staff revisited as Omicron replaces Delta

Regulations making vaccines a condition of deployment for health and social care staff are set to be revoked, subject to public consultation and parliamentary approval, the Health and Social Care Secretary has announced.

BA.2 sublineage of Omicron shows increased immune evasion and transmission

Recently, researchers from the University of Copenhagen have been investigating the spread of two sublineages of the Omicron variant among Danish households.

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.

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.

How many lives would vaccine sharing have saved?

In a new study, researchers have been investigating different COVID-19 vaccine sharing simulations, and how they would affect affect global mortality.

States were sharing covid test kits. Then omicron hit.

In a few short months, states have gone from donating surplus rapid covid-19 tests to states with shortages to hoarding them as demand driven by the spike in cases strains supplies.

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."

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.

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.

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.
