Study reports lasting immune response in convalescent COVID-19 patients

Researchers report the cellular immune response of convalescent patients in Germany, who recovered from mild or moderate infection compared to that of healthy people with no history of COVID-19.

Study of children hospitalized with COVID-19 shows 2% mortality

The COVID-19 pandemic caused by SARS-CoV-2 has been observed to be less serious in infants and children. However, this age group is also subject to certain complications following infection. A new study describes the findings of an observational study of children hospitalized with SARS-CoV-2 infection in several different hospitals across three countries.

Corticosteroid receptor inhibitor shows anti-SARS-CoV-2 activity in vivo

A team of researchers examined PT150, which is an allosteric modulator of androgen and glucocorticoid receptors, to assess whether it had any antiviral activity or immunomodulatory activity to decrease the hyperinflammatory response of SARS-CoV-2 infection.

Could laser-facilitated epicutaneous vaccination for SARS-CoV-2 be an alternative to intramuscular injection?

Scientists at the University of Salzburg and Pantec Biosolutions AG have developed a laser-facilitated epicutaneous immunization against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein. The model has induced angiotensin-converting enzyme 2 (ACE2) blocking antibodies in mice.

Countries with older populations have higher SARS-CoV-2 infections and deaths, says study

A new study examines some patterns revealed by a study of the factors operating in different regions and countries, to offer plausible hypotheses of these variations.

23 Feb 2021

More diverse SARS-CoV-2 variants identified within infected children than in adults

A new study describes the identification of multiple circulating variants of SARS-CoV-2 during this early pandemic period from Asia and Europe. In addition, there were multiple local introductions of different variants, that resulted in multiple waves of transmission.

Neanderthal gene can confer protection against severe COVID-19, finds study

A new study has detailed how some of the genes in the human genome inherited from Neanderthals appear to confer a protective effect against severe COVID-19.

Why can SARS-CoV-2 infection cause neurological and cardiovascular symptoms?

Researchers from Columbia University Vagelos College of Physicians & Surgeons, USA, present results linking oxidative stress and the activation of a biochemical pathway associated with Alzheimer’s disease to SARS-CoV-2 infection.

22 Feb 2021

Some SARS-CoV-2 variants evade mRNA vaccine-induced humoral immune, says study

Understanding how variants escape vaccine-boosted immune function is necessary to neutralizing SARS-CoV-2. An international team of researchers from MIT and Harvard University in the USA analyzed Pfizer and Moderna vaccines' effectiveness in neutralizing spike proteins from 10 different strains of SARS-CoV-2.

Researchers find CXCR6 gene plays a role in COVID-19 severity

Researchers in the United States have conducted a study demonstrating that a gene called CXCR6 (C-X-C Motif Chemokine Receptor 6) may play an important role in determining the severity of COVID-19.

Study forecasts post-COVID-19 hospital activity among children and young people in England

An intriguing new study by researchers in the UK explores attendance and admissions in various hospital areas, including inpatient – outpatient and emergency department (ED) – by children and up to 24 years olds (children and young people, CYP).

Bats and pangolins in Southeast Asia harbor SARS-CoV-2-related coronaviruses, study finds

A new study has reported evidence that SARS-CoV-2-related coronaviruses (SC2r-CoVs) are circulating in bats in Southeast Asia. This has extended the geographical area where SC2r-CoVs are found, underscoring the urgency of identifying the immediate ancestor of SARS-CoV-2.

17 Feb 2021

The origin of SARS-CoV-2 furin cleavage site remains a mystery

A new study discusses the origin of the furin cleavage site on the SARS-CoV-2 spike protein, which is responsible for the virus’s relatively high infectivity compared to relatives in the betacoronavirus subgenus.

What are the main food safety concerns associated with the COVID-19 pandemic?

A new study deals with the main food safety concerns associated with the COVID-19 pandemic.

17 Feb 2021

Researchers study host and viral transcriptomes in tandem to shed light on SARS-CoV-2 infection

In a new study, researchers discuss the use of simultaneous sequencing of both human and viral genes to better understand SARS-CoV-2's infection pathway.

15 Feb 2021

Could a SARS-CoV-2 accessory protein be responsible for certain COVID-19 symptoms?

Researchers highlight the potential causes of some COVID-19 symptoms. Early in the pandemic, the hallmark symptoms of COVID-19 include cough, fever, and shortness of breath. As the pandemic has evolved, more symptoms have emerged, such as loss of smell and taste, headache, intestinal issues, and abdominal pains.

New study supports UK’s delay of the SARS-CoV-2 Pfizer vaccine second dose

After reanalyzing data from 500,000 people in Israel who received the Pfizer vaccine, researchers suggest a single dose provides sufficient immunity after about 21 days, thus providing support for the UK’s decision to delay the second dose to 12 weeks.

India’s COVID-19-related hygiene promotion campaign shows some positive results

A new study explores the results of such hygiene promotion campaigns on handwashing practices in rural Odisha, India.

U.S. public divided over COVID-19 “immunity passports” idea

A nationally representative survey conducted in the U.S. suggests that the public is fairly evenly divided in its support of immunity certificates or “passports” to enable the selective lifting of restrictions placed on people during the COVID-19 pandemic.
