Study examines SARS-CoV-2 seropositivity in healthy young adults and risk of reinfection

New research has been published in The Lancet Respiratory Medicine, which focuses on evaluating the effect of SARS-CoV-2 seropositivity on the possibility of developing SARS-CoV-2 infection in a young and healthy population. This study is based on the longitudinal prospective cohort study that involves the COVID-19 Health Action Response for Marines (CHARM).

Gut's immune response in COVID-19 patients may not provide adequate protection to other organs

Our guts may not provide long-lasting systemic immunity from COVID-19, which is where immune cells circulate through the body to provide protection to other organs, finds a new study published in Frontiers in Immunology.

Eviction bans authorized during COVID-19 pandemic reduced the infection rate, indicates study

A new study led by researchers at Johns Hopkins and the University of Pennsylvania uses computer modeling to suggest that eviction bans authorized during the COVID-19 pandemic reduced the infection rate and not only protected those who would have lost their housing but also entire communities from the spread of infections.

New machine-learning program accurately identifies COVID-19 conspiracy theories on social media

A new machine-learning program accurately identifies COVID-19-related conspiracy theories on social media and models how they evolved over time--a tool that could someday help public health officials combat misinformation online.

Use of ozone as a decontaminant for SARS-CoV-2

Researchers in Germany have demonstrated how an ozone-based decontamination device significantly reduces the volume of viral residue left on surfaces of two surrogate viruses for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Sinovac COVID-19 vaccine shows 50% effectiveness in a cohort of Brazilian healthcare workers

CoronaVac is a well-tolerated vaccine containing inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and it induced humoral responses in phase 1 and 2 studies. Analysis of a Brazilian phase 3 clinical trial that evaluated 12,607 participants showed that the vaccine had an efficacy of 50.39% 15 days after the 2nd dose.

COVID-19 patients who are overweight or obese may develop a more severe infection

COVID-19 patients who are overweight or obese are more likely to develop a more severe infection than patients of healthy weight, and they require oxygen and invasive mechanical ventilation more often. There is no increased risk of death .

Researchers show how to evaluate waning efficacy of COVID-19 vaccines

Researchers in the United States have demonstrated how to estimate the potentially waning efficacy of vaccines designed to protect against infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

19 Apr 2021

Researchers manufacture the SARS-CoV-2 RBD in pichia

Researchers in the United States and India have developed a high-volume, low-cost platform for manufacturing vaccines to protect against different variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Researchers develop computational model to predict changes in SARS-CoV-2’s viral fitness

Two researchers from the Université Libre de Bruxelles in Belgium, Fabrizio Pucci and Marianne Rooman, recently built a simplified computational model, called SpikePro, to predict the SARS-CoV-2 fitness from the amino acid sequence and structure of the spike protein. This study focuses on the spike protein’s stability and the binding affinity to the host receptor.

Could a tuna-derived protein inhibit SARS-CoV-2?

A recent study in the journal Food Chemistry draws attention to the need for finding nutritional supplements with potential SARS-CoV-2 inhibition effects in the wake of the COVID-19 pandemic.

19 Apr 2021

Plant-derived compound isorhamnetin may have antiviral potential against SARS-CoV-2

The lack of new or repurposed drugs to treat patients with severe or critical COVID-19 has been one of the biggest hurdles to reducing mortality rates in the ongoing pandemic caused by SARS-CoV-2. A new study describes the potential for the use of the plant molecule isorhamnetin in the management of this virus.
