People who received Pfizer-Biontech vaccine have lower antibody levels targeting the delta variant

Levels of antibodies in the blood of vaccinated people that are able to recognise and fight the new SARS-CoV-2 Delta variant first discovered in India (B.1.617.2) are on average lower than those against previously circulating variants in the UK, according to new laboratory data from the Francis Crick Institute and the National Institute for Health Research (NIHR) UCLH Biomedical Research Centre, published today (Thursday) as a Research letter in The Lancet.

New study sheds light on why many COVID-19 patients suffer from hypoxia

A new study published in the journal Stem Cell Reports by University of Alberta researchers is shedding light on why many COVID-19 patients, even those not in hospital, are suffering from hypoxia--a potentially dangerous condition in which there is decreased oxygenation in the body's tissues.

COVID-19 had claimed more than 3 million lives worldwide in 2020

By the end of 2020, COVID-19 had claimed the lives of more than three million people worldwide, representing 1.2 million more deaths than officially reported earlier, says a newly released report by the World Health Organization (WHO).

Person infected with SARS-CoV-2 can transmit infection to three to five other people

What started as the preliminary analysis of routine laboratory data has since evolved into the largest-ever study of viral load levels in patients with SARS-CoV-2.

Discovery of novel SARS-related coronaviruses in bats

In a recent study published on the bioRxiv* server, Peng Zhou, Zheng-Li Shi and colleagues at the Wuhan Institute of Virology, with collaboration from scientists at the University of Chinese Academy of Sciences in China, have identified a new lineage of SARS-related coronaviruses that utilize bat angiotensin-converting enzyme 2 (ACE2) receptors for cell entry, which is the same receptor used by SARS-CoV-2 to infect host cells.

Researchers speculate the low prevalence of COVID-19 in Japan

Protective immune memory--through B cells, which make antibodies, and/or T cells, which in the case of CD8+ T cells can kill virus-infected cells--can be induced by identical but also by related viruses.

To the bat cave: In search of covid’s origins, scientists reignite polarizing debate on Wuhan ‘lab leak’

Once dismissed as a conspiracy theory, the idea that the covid virus escaped from a Chinese lab is gaining high-profile attention. As it does, reputations of renowned scientists are at risk — and so is their personal safety.

New coronavirus variants can be effectively eliminated by disinfection, thorough hand washing

The researchers found that the variants have a similar surface stability as the wild type virus under laboratory conditions, but can be effectively eliminated by disinfection and thorough hand washing, heat or alcohol treatment.

Moderna and Pfizer-BioNTech vaccines induce robust T cell response against SARS-CoV-2 variants

Researchers in the United States have conducted a study showing the efficacy of the Moderna and Pfizer-BioNTech vaccines at eliciting a robust T cell response against variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Scientists identify receptor in cells that could be key to preventing cancer drug-induced hearing loss

University of Alberta scientists have identified a receptor in cells that could be key to preventing permanent hearing loss in childhood cancer survivors who are being treated with the drug cisplatin.

Study reveals how oral antiviral drug works to attack SARS-CoV-2 virus

A University of Alberta virology lab has uncovered how an oral antiviral drug works to attack the SARS-CoV-2 virus, in findings published May 10 in the Journal of Biological Chemistry.

MIT researchers generate the complete gene annotation of SARS-CoV-2 genome

In early 2020, a few months after the Covid-19 pandemic began, scientists were able to sequence the full genome of the virus that causes the infection, SARS-CoV-2. While many of its genes were already known at that point, the full complement of protein-coding genes was unresolved.

Cancer researchers receive $3 million NCI grant to study cognitive dysfunction after chemotherapy

Cancer researchers at the University of Pittsburgh School of Medicine and Indiana University received a five-year, $3 million grant from the National Cancer Institute (NCI) to study cognitive dysfunction after chemotherapy.

Immunocompromised children and young adults may experience prolonged SARS-CoV-2 infection

Children and young adults with compromised immune systems, such as those undergoing cancer treatment, may experience a prolonged period of infection with SARS-CoV-2, the virus that causes COVID-19, and the extended duration of infection may increase the incidence of mutations.

SARS-CoV-2 infection induces polyfunctional antibodies that can destroy infected cells

Drawing on epidemiological field studies and the FrenchCOVID hospital cohort coordinated by Inserm, teams from the Institut Pasteur, the CNRS and the Vaccine Research Institute (VRI, Inserm/University Paris-Est Créteil) studied the antibodies induced in individuals with asymptomatic or symptomatic SARS-CoV-2 infection.

Experimental antiviral drug for COVID-19 shows effectiveness in hamster models

The experimental antiviral drug MK-4482 significantly decreased levels of virus and disease damage in the lungs of hamsters treated for SARS-CoV-2 infection, according to a new study from National Institutes of Health scientists.

More SARS-CoV-2 variants have emerged from immunocompromised hosts, shows research

A number of SARS-CoV-2 variants have emerged from immunocompromised hosts, research has identified. It is thought that variants of concern - including B.1.1.7, a variant first identified in Kent - were a result of long-term infection in people with a weakened immune system.

Population-based study shows the persistence of neutralizing antibodies against coronavirus

It is an open question to what extent protection against reinfection persists after overcoming a SARS-CoV-2 infection.
