Colonization by SARS-CoV-2 not synonymous with infection, screening study highlights

A new study released as a preprint on the medRxiv* server throws cold water on this notion, however, by demonstrating that in a set of asymptomatic cases, less than a tenth actually had evidence of SARS-CoV-2 infection. This finding has serious implications for the practices mentioned above, since they may be neither justifiable nor cost-effective as means to break the chain of viral transmission.

“React and inject”: synthetic peptide-modified nanodiamonds as emergency pan-coronavirus vaccines

A recent study published in the MDPI journal, Pathogens, describes a coronavirus peptide vaccine antigen in the form of nanodiamond-based formulations, that demonstrated a robust and long-lasting immune response. The nanodiamonds proved to be a powerful and versatile platform for antigen conjugation. This could make it a safe and effective strategy for the production of off-the-shelf vaccines against multiple coronaviruses.

Study: Diet rich in fermented foods boosts microbial diversity, decreases inflammation

A diet rich in fermented foods enhances the diversity of gut microbes and decreases molecular signs of inflammation, according to researchers at the Stanford School of Medicine.

Millions of COVID-19 cases went undetected in the first six months of the pandemic, finds study

A new report published in the journal Science Translational Medicine estimates that potentially 16.8 million Americans were infected but not officially diagnosed with SARS-CoV-2 by July 2020. In addition, the results suggest there were nearly five undetected coronavirus cases for every diagnosed coronavirus infection in the first six months of the pandemic.

mRNA-based COVID-19 vaccine CV07050101 demonstrates limited immunogenicity in non-human primates

Scientists from the US and Germany have recently evaluated the efficacy of an mRNA-based COVID-19 vaccine candidate, CV07050101, in inducing humoral and cellular immune responses in non-human primates. The study reveals that prime-boost immunization with the vaccine candidate induces only limited immunity against SARS-CoV-2.

Composition and structure of nasopharyngeal microbiome relate to COVID-19 disease severity

Breathing treatments are provided to hospitalized COVID-19 patients. In this study, the researchers examined the community composition in relation to three attributes - COVID-19 status, breathing assistance, and antibiotic use. This study is published in the journal, Applied Microbiology.

Pfizer aims to implement boosters and a new vaccine based on SARS-CoV-2 Delta variant

The drugmaker Pfizer, one of the companies behind the Pfizer-BioNTech vaccine, or BNT162b2, awaits the green light to develop a COVID-19 booster shot that can protect against emerging variants. Pfizer’s COVID-19 vaccine has been shown to be 95% effective in an ongoing large-scale clinical trial against the original SARS-CoV-2 strain.

SARS-CoV-2 immunity due to prior infection or vaccination is similar, study says

A new study finds that the rate of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reinfection is low following one episode of the infection.

Scientists analyze the sensitivity of SARS-CoV-2 Delta variant to monoclonal antibodies

The Delta variant was detected for the first time in India in October 2020 and has since spread throughout the world.

Durable antibody response at least 8 months following vaccination with J&J COVID vaccine

A recent study by a team of scientists at Beth Israel Deaconess Medical Center and Janssen Vaccines & Prevention has demonstrated that humoral and cellular immunity elicited by the coronavirus disease 2019 (COVID-19) vaccine Ad26.COV2.S remains active for at least eight months.

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.

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.

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.

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.

Study uncovers the complex cellular mechanisms of Ebola virus

Mount Sinai researchers have uncovered the complex cellular mechanisms of the Ebola virus, which could help explain its severe toll on humans and identify potential pathways to treatment and prevention.

Enzyme inhibitor boosts immune system to fight MRSA and other dangerous skin infections

In what turned out to be one of the most important accidents of all time, Scottish bacteriologist Alexander Fleming returned to his laboratory after a vacation in 1928 to find a clear zone surrounding a piece of mold that had infiltrated a petri dish full of Staphylococcus aureus (S. aureus), a common skin bacterium he was growing.

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.
