Potent monoclonal antibody shows promise against emerging SARS-CoV-2 variants of concern

In a new study currently available on the bioRxiv* preprint server, a group of US-based researchers developed a panel of neutralizing monoclonal antibodies against SARS-CoV-2 that can block viral attachment to cells – and pinpointed a specific one that can potently neutralize all tested variants of concern.

Safety and efficacy of Pfizer and AstraZeneca COVID-19 vaccines even better than clinical trials predicted

Researchers in the UK and United States have demonstrated the efficacy of one dose of either the Pfizer-BioNTech or Oxford-AstraZeneca vaccine against infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a real-world community setting in the UK.

Recovered COVID-19 patients show signs of long-term immunity

A study conducted by researchers in the United States has found that most patients who recovered from coronavirus disease 2019 (COVID-19) showed signs of long-lasting immunity against the causative agent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Higher ratio of green spaces associated with reduced disparity in coronavirus infection rates

A higher ratio of green spaces at the county level is associated with a lower racial disparity in coronavirus infection rates, according to a new study.

Brazilian coronavirus variant could pose a bigger threat than previously assumed

A new study with the University of Copenhagen represented indicates that the coronavirus variant called P.1, which originated in Brazil, could pose a bigger threat than previously assumed.

Cloth face masks can be as effective as surgical masks in reducing transmission of COVID-19

Researchers from the Universities of Bristol and Surrey have found that well-fitting, three-layered cloth masks can be as effective at reducing the transmission of COVID-19 as surgical masks.

Study examines mRNA COVID-19 vaccine’s effectiveness across age and gender

The findings reveal that although the two-dose vaccine regimen initially induces robust antibody response in all age groups, older male individuals are particularly associated with a gradual decline in vaccine-induced immunity six weeks after the second vaccine dose.

Study observes increase in Lyme disease-causing ticks across California’s woodlands and beaches

US-based researchers – at Colorado State University and the Northern Arizona University – have discovered that disease-causing ticks are finding their way onto beachfront properties, including infestations in woodlands and beaches around North California.

Can control theory explain differences in virulence and transmission of SARS-CoV-2?

A new study discusses variations in viral pathogenicity and in transmission, which are responsible for asymptomatic infection and for superspreading events. The ability to understand this would open the way to understand how this virus behaves the way it does, in terms of its virulence, its spread, and its emergent variants of concern.

COVID-19 donor antibodies show broad cross-reactivity against SARS-CoV-2 variants and related viruses

A new study reports on a set of antibodies from COVID-19 donor serum, which seems to be cross-reactive across multiple Sarbecoviruses, including the very similar SARS-CoV-2, SARS-CoV and Middle East Respiratory Syndrome (MERS)-CoV.

Peptide nucleocapsid vaccine candidate elicits protective T cell immunity against SARS-CoV-2 in vivo

A new study describes a synthetic peptide used as a platform to generate protective adaptive cellular immunity to the virus in rhesus macaques, which are the gold standard for preclinical testing in humans.

Ohio’s Amish suffered a lot from Covid, but vaccines are still a hard sell

The Amish communities of northeastern Ohio engage in textbook communal living. Families eat, work and go to church together, and through the pandemic, mask-wearing and physical distancing have been spotty. That has meant that these communities bore a high rate of infection and death.

SARS-CoV-2 recruits heme metabolites in antibody evasion

A research paper recently published in the journal Science Advances by Cherepanov et al. (April 22nd, 2021) demonstrated that the NTD binds to biliverdin, a product of heme catabolism, leading to enhanced antibody escape at physiologically relevant concentrations.

Horizontal transmission route is responsible for HTLV-1 uveitis

Human T-cell lymphotropic virus type-1 (HTLV-1) is a retrovirus similar to human immunodeficiency virus (HIV) and has mostly been thought to be transmitted vertically (mother-to-child), or horizontally (sexually or parenterally (e.g. via blood transfusion)).

Scientists design 'smart' cellular biosensors for detecting SARS-CoV-2 spike

New research led by Hana El-Samad of the University of California, San Francisco, and the Chan-Zuckerberg Biohub confirmed the beneficial use of an antiviral therapeutic called SARSNotch, which uses a combination of the SynNotch platform and de-novo designed protein binders. SARSNotch uses sentinel T cells to detect and mount a genetic response toward the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein.

Municipalities with low socioeconomic status in Greater Santiago have higher COVID-19 mortality

People up to age 40 living in economically depressed municipalities in the Greater Santiago, Chile, metropolitan area were three times more likely to die as a result of the infection than their counterparts in wealthier areas, researchers report in the journal Science.

Why do we lose our sense smell/taste with COVID?

The angiotensin-converting enzyme 2 (ACE2) enzyme attached to the membranes of cells is the entry point for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). They are abundantly found all over the body and most prominently in the lungs and nose.

Neonates exposed to SARS-CoV-2 can sustain adverse health outcomes

The incidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission from mothers to newborns appears low and may be linked to biological as well as social factors. However, studies focusing on the factors associated with neonatal viral testing outcomes.

SARS-CoV-2 virus neutralized with half-second exposure to very high temperature

As reported in the journal Biotechnology and Bioengineering, the team from Texas A&M University developed a simple fluidics system that measures the sub‐second heat inactivation of coronaviruses.

Clinical trial to test existing antibiotic for treating serious S. aureus infections begins

A clinical trial to test the antibiotic dalbavancin for safety and efficacy in treating complicated Staphylococcus aureus (S. aureus) bacteremia has begun.
