Researchers develop a novel probiotic formulation with high anti-SARS-CoV-2 potency

A team of international scientists recently conducted a randomized clinical trial to assess the safety and efficacy profiles of a novel probiotic formulation in symptomatic coronavirus disease 2019 (COVID-19) patients. The findings indicate that the probiotic formulation is highly effective in reducing symptom severity in COVID-19 patients without causing any adverse events.

SARS-CoV-2 UK variant may induce more inflammation, study suggests

Since COVID-19 was first detected in December 2019 in Wuhan, China, many different variants of its causative virus – SARS-CoV-2 – have emerged. Through increased viral fitness, some of these have risen to predominance over earlier variants in a remarkably short period of time. New research, by a team of scientists at major institutions in France, examines the reasons behind this phenomenon in one such variant of concern (VOC), the so-called UK variant.

New testing protocol for SARS-CoV-2 can process thousands of samples within 48 hours

Researchers at the Vienna BioCenter designed a testing protocol for SARS-CoV-2 that can process tens of thousands of samples in less than 48 hours. The method, called SARSeq, is published in the journal Nature Communications and could be adapted to many more pathogens.

Could 6′,6′-difluoro-aristeromycin (DFA) have broad-spectrum antiviral potential against coronaviruses?

Researchers at the Leiden University Medical Center demonstrated that low-micromolar concentrations of 6′,6′-difluoro24 aristeromycin (DFA), an adenosine nucleoside analog, strongly inhibits the replication of Middle East respiratory syndrome coronavirus (MERS-CoV) in a cell-based infection assay.

Heterologous prime-boost immunization with AstraZeneca and Pfizer COVID-19 vaccines safe and well-tolerated, study finds

A team of scientists from Germany has recently evaluated the reactogenicity profile of heterologous ChAdOx1 nCoV-19/BNT162b2 prime-boost vaccination among healthcare workers. The findings reveal that a 12-week interval regimen of heterologous vaccination is well-tolerated among participants. The study is currently available on the medRxiv* preprint server.
