B.1.1.7 SARS-CoV-2 variant significantly more dangerous

Now, researchers at the University of Exeter, the NHS Foundation Trust, report a significant increase in mortality risk due to the B.1.1.7 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant.

SARS-CoV-2 infection is circadian

An international team of researchers has found that angiotensin-converting enzyme 2 (ACE2) levels in lung cells vary over the day, affecting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The virus entry and replication in the lung cells also have a rhythmic cycle, suggesting circadian processes can affect the virus's life cycle.

RedHill provides opaganib treatment under compassionate use exemption for Swiss COVID-19 patients

RedHill Biopharma Ltd., a specialty biopharmaceutical company, today announced that it has acted on a request to provide opaganib treatment on an outpatient basis under compassionate use exemption for several Swiss patients suffering from COVID-19 pneumonia.

Anti-androgen drugs may help disarm coronavirus spike protein, stop progression of COVID-19

Hormone drugs that reduce androgen levels may help disarm the coronavirus spike protein used to infect cells and stop the progression of severe COVID-19 disease, suggests a new preclinical study from researchers in the Abramson Cancer Center at the University of Pennsylvania and published online in Cell Press's iScience.

AstraZeneca's COVID-19 vaccine protects against symptomatic disease

Results from a large clinical trial in the United States and South America indicate that AstraZeneca's COVID-19 vaccine, AZD1222, is well-tolerated and protects against symptomatic COVID-19 disease, including severe disease or hospitalization.

Researchers develop new method for measuring immunity to coronavirus

Igor Stagljar made his career building molecular tools to combat cancer. But when the pandemic hit last March, he aimed his expertise at a new adversary, SARS-CoV-2.

Can SARS-CoV-2 still be transmissible once symptoms have subsided?

Researchers based at the University of Missouri, in partnership with U.S. government science facilities in Maryland, have reported that individuals severely infected with SARS-CoV-2 may be able to continue shedding infectious viral RNA for over three weeks after the symptomatic infection has passed.

Prediction of antibody responses in recovered COVID-19 patients remains unclear

It is crucial to gain a better understanding of how an antibody response is developed against SARS-CoV-2, and how long it lasts. This will determine the antibody titers and duration that protect against reinfection by the virus. A new preprint on the medRxiv* server shows this to be still a distant goal.

Male fertility and androgen production may be impacted by COVID-19

An interesting new study has appeared online in the journal Hormones that discusses the effects of COVID-19 on the male and female gonads.

What are the chief predictors of SARS-CoV-2 infection in children?

A new study seeks to explore the factors associated with the diagnosis in children. The ability to rapidly diagnose COVID-19 in this age group is essential not only for monitoring progressive disease in individual children, but to avert further transmission chains.

The hype has faded, but don’t count out convalescent plasma in Covid battle

Six months after it was controversially hailed by Trump administration officials as a "breakthrough" therapy to fight the worst effects of Covid-19, convalescent plasma appears to be on the ropes.

In America, Covid vaccine eligibility is a ‘crazy quilt’ of state rules

In North Carolina, the nation's leading tobacco producer, any adult who has smoked more than 100 cigarettes in their lifetime can now be vaccinated against Covid.

Could nanoparticle vaccines offer broad protection against sarbecoviruses?

To understand the ability of SARS-CoV-2 vaccine-elicited antibodies to neutralize and protect against emerging variants (that are pathogenic) and other sarbecoviruses, a large team of researchers studied immunity by receptor-binding domain nanoparticle vaccines. They showed that a clinical-stage multivalent SARS-CoV-2 receptor-binding domain nanoparticle vaccine (SARS-CoV-2 RBD-NP) protected mice from the SARS-CoV-2-induced disease.

Vaccine passports raise questions of equity, security, and privacy

Vaccine passports raise questions of equity, security, privacy, argues Crispin Maslog. China, where the COVID-19 pandemic began a long year ago, has now become the first country in the world to issue a vaccine passport to promote world economic recovery and facilitate cross-border travel.

Asymptomatic individuals the biggest problem in COVID battle

The researchers noted in a study published in the journal Science, that asymptomatic cases are those that do not manifest symptoms for the infection duration. In contrast, presymptomatic cases develop symptoms later in the course of infection.
