Study finds higher pediatric SARS-CoV-2 burden than previously reported in the U.S.

In a new study, published on the pre-print server medRxiv*, researchers at Inova Children's Hospital and the George Mason University revealed that a much higher burden of SARS-CoV-2 infection was found in children than previously reported. This comes after the researchers assessed seropositivity among 1,038 children and adolescents.

Novel strategy redirects generic antibodies to SARS-CoV-2 spike proteins

The SARS-CoV-2, the new coronavirus behind the current pandemic, infects humans by binding its surface-exposed spike proteins to ACE2 receptors exposed on the cell membranes.

Airborne Infection Rate index predicts timing of second wave of pandemic

The "second wave" of the coronavirus pandemic has placed much blame on a lack of appropriate safety measures. However, due to the impacts of weather, research suggests two outbreaks per year during a pandemic are inevitable.

J&J SARS-CoV-2 vaccine shows immunity in non-human primates 6 months after vaccination

A new preprint research paper released on the bioRxiv server discusses the findings from a model that assesses the association between the immunogenicity and protection conferred by a set of adenovirus- (Ad26)-vectored vaccines that express stabilized SARS-CoV-2 spike protein.

Two-dose regimen of adenovirus-based vaccine offers 91.6% efficacy against COVID-19

An interim analysis of data from the phase 3 trial of the COVID-19 vaccine from Russia (Gam-COVID-Vac) suggests that a two-dose regimen of the adenovirus-based vaccine offers 91.6% efficacy against symptomatic COVID-19.

Rapid SARS-CoV-2 antigen test improved with silver amplification

A new preprint posted to the medRxiv server describes the use of silver amplification technology to develop a sensitive, rapid antigen test for COVID-19.

Prone positioning associated with lower mortality and intubation in COVID-19 patients

In the absence of specific antivirals to combat the pandemic, supportive care is paramount. In this context, a new preprint posted to the medRxiv server describes the observed efficacy of prone positioning to reduce mortality and the risk of intubation in COVID-19 patients with respiratory insufficiency.

Single-dose vaccination effective for healthcare workers with prior SARS-CoV-2 infection

The findings reveal that healthcare workers previously infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) develop significantly higher antibody titers in response to a single dose of COVID-19 vaccine, as compared to healthcare workers without prior SARS-CoV-s infection. The study is currently available on the medRxiv* preprint server.

Highly conserved neutralizing epitope identified on SARS-CoV-2 spike protein

A recent study conducted at the University of Texas at Austin, USA, has identified a highly conserved neutralizing antibody binding site on the spike S2 domain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The study findings might help develop novel spike-targeting antibodies for widespread protection. The study is currently available on the bioRxiv preprint server.

Immune profiling shows differences in COVID-19 and influenza pathologic pathways

A study conducted at Johns Hopkins University School of Medicine in Baltimore has revealed distinct differences in the immune pathways that are activated by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and those that are activated by influenza.

ECMO life-support therapy can increase odds of survival for critically-ill COVID-19 patients

COVID-19 has caused more than 2 million deaths worldwide since the World Health Organization declared it a pandemic in March 2020.

Study finds link between lack of ICU beds and patient mortality during COVID-19 pandemic

A new study by Yale researchers found a significant association between the availability of hospital resources -- particularly ICU beds -- and patient mortality during the early weeks of the COVID-19 pandemic.

Previous SARS-CoV-2 infection may negate need for two vaccine doses

Researchers in the United States have shown that two doses of vaccine may not be necessary to protect against coronavirus disease 2019 (COVID-19) among people who have already been infected with the causative agent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Study shows link between periodontitis and COVID-19 complications

COVID-19 patients are at least three times more likely to experience complications if they also have gum disease, according to research published today in the Journal of Clinical Periodontology, the official publication of the European Federation of Periodontology.
