Breakthrough SARS-CoV-2 infection among fully vaccinated likely to be less transmissible

Researchers in the United States have conducted a study suggesting that individuals fully vaccinated against coronavirus disease 2019 (COVID-19) who develop breakthrough infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are less likely to transmit the virus to others than unvaccinated infected individuals.

Early B cell signatures predict antibody responses to mRNA-based COVID-19 vaccine

Researchers in the United States have identified both antigen-specific and antigen non-specific predictive signatures of antibody responses to Moderna’s two-dose coronavirus disease 2019 (COVID-19) vaccine that protects against infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Intranasal COVID-19 vaccine protects animals against lethal COVID-19 infection

In a new study assessing the potential of a single-dose, intranasal COVID-19 vaccine, a team from the University of Iowa and the University of Georgia found that the vaccine fully protects mice against lethal COVID-19 infection.

Kids misusing soft drinks to corrupt SARS-CoV-2 tests

A group of collaborating researchers systematically tested a variety of different soft drinks to determine their ability to create false-positive results.

Instant biosensor can detect COVID-19 variants even if someone is asymptomatic

RMIT University is collaborating with partners including Australian biomedical start-up Soterius on the biosensor, which can detect the presence of tiny amounts of the SARS-CoV-2 virus and its variants.

Researchers uncover genetic markers associated with COVID-19 infection risk and severity

An international collaboration uncovers several genetic markers associated with SARS-CoV-2 infection and COVID-19 severity.

Repurposed drugs for COVID-19 treatment identified through virtual screening and cell-based assays

A joint research group from KAIST and Institut Pasteur Korea has identified repurposed drugs for COVID-19 treatment through virtual screening and cell-based assays.

A type of echocardiogram may predict COVID-19 patients most at risk of developing atrial fibrillation

Researchers at Johns Hopkins Medicine have shown that a type of echocardiogram, a common test to evaluate whether a person's heart is pumping properly, may be useful in predicting which patients with COVID-19 are most at risk of developing atrial fibrillation - an irregular heartbeat that can increase a person's risk for heart failure and stroke, among other heart issues.

Study examines children's emotional wellbeing throughout COVID-19 pandemic

A new study, released as a preprint on the medRxiv* server, reports the effects of such limited interactions on the emotional health of very young children, as reported by closely involved parents.

How women in England faced childbirth in the COVID-19 pandemic

Pregnant women have suffered considerable uncertainty during the COVID-19 pandemic. Not only were the effects of the virus on the baby unknown, but social restrictions in place threatened their ability to plan their delivery experience or have their birthing partners with them. This is the focus of a new paper, which illustrates the need to provide proper guidance and support to pregnant women during such periods, especially allowing them to feel supported and in control of their childbirth experience.

Do lockdowns exert selection pressure on overdispersion of SARS-CoV-2 variants?

New research recently released on the medRxiv* preprint server describes a mathematical model that has been developed to evaluate competitions between variants that differ in their level of overdispersion (k) and their mean infectiousness.

How do host factors like the lung microbiome aid in SARS‐CoV‐2 infection?

A new article has been published in Cellular and Molecular Lifesciences, which focuses on the connection between host factors and the worsening of the COVID-19. Further, the impact of the virus on the host’s microbiome and secondary infection has also been studied.

Using regular monitoring is most effective in limiting COVID-19 outbreaks in schools

Current methods of limiting the spread of COVID-19 infection in schools are unsuited for controlling outbreaks, with research indicating that regular monitoring measures may be better suited.

Delta variant surges in Colorado as the bands play on

Dr. Rachel LaCount grasped a metal hoop at a playground and spun in circles with her 7-year-old son, turning the distant mesas of the Colorado National Monument into a red-tinged blur.

Most inmates have had their covid shots — but their guards likely haven’t

When the number of covid-19 cases among inmates in Pennsylvania state prisons last fall topped 1,000 and staff cases hovered in the hundreds, the union representing 11,000 corrections officers began lobbying to get prison staffers to the front of the line for vaccinations.

Women at higher risk of post-COVID-19 syndrome

To better understand post-COVID sequelae, researchers at the University Hospital Basel and the University Hospital Zurich conducted a multicentre prospective observational cohort study.

Growing concern over SARS-CoV-2 Lambda variant

A new report from Chile – currently available on the medRxiv* preprint server – reveals how mutations in the spike glycoprotein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Lambda variant can confer protection from neutralizing antibodies and increase viral infectivity rates, which means massive vaccination campaigns should be accompanied by strict genomic surveillance.

Striking increase in SARS-CoV-2 antibodies seen with prime dose AstraZeneca vaccine followed by Pfizer-BioNTech

Researchers in Germany have provided evidence that a booster shot of a messenger RNA (mRNA)-based coronavirus disease 2019 (COVID-19) vaccine following prime immunization with AstraZeneca’s adenoviral vector-based vaccine is sufficient to achieve high levels of neutralizing antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Changes to COVID-19 vaccination strategy could speed up herd immunity

Researchers in the United States have proposed changes to the current coronavirus disease 2019 (COVID-19) vaccination strategy that they say would increase the likelihood of herd immunity being achieved in the most timely and cost-effective manner.

Scientists study how our immune system responds to COVID-19 variants

Australian scientists researching how our immune system responds to COVID-19 have revealed that those infected by early variants in 2020 produced sustained antibodies, however, these antibodies are not as effective against contemporary variants of the virus.
