Australia's response to COVID-19 pandemic

In a recent paper, Australia's response to the COVID-19 pandemic is described, identifying the factors that contributed most to the countries success.

Discovery of diverse sarbecovirus broadly neutralizing antibodies from SARS-CoV-2 “infected-vaccinated” humans

Scientists were inspired by the robust serum nAb responses in people who recovered from natural SARS-CoV-2 infection and were later vaccinated using mRNA vaccine. They isolated and characterized bnAbs from two COVID-19 convalescent donors who were recently vaccinated. These isolated bnAbs were found to be highly potent against sarbecoviruses. This research is available on the bioRxiv* preprint server.

Research suggests current smokers not at excess risk of SARS-CoV-2 infection

Now, a new study published on the bioRxiv* preprint server investigates this relationship further and suggests that current smoking is not associated with a higher incidence of SARS-CoV-2 infection.

As COVID restrictions were removed, Texas saw an increase in seasonal respiratory virus infections

Like many US states, Texas introduced many different measures to reduce the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), such as masking, social distancing, and the closure of public services and businesses likely to aid the spread of disease.

An investigation of SARS-CoV-2 infections among Australian passengers on the Diamond Princess cruise ship

The Diamond Princess Cruise ship left Yokohama (Japan) on 20 January 2020, for a fourteen-day tour with shore excursions in Japan, Hong Kong, Vietnam, and Taiwan. Unfortunately, one of the passengers who complained of mild dry cough was later confirmed to be SARS-CoV-2 positive. In due course, 19% of the passengers were infected with the virus, and thirteen people died.

Acid pH enhances SARS-CoV-2 infection by up-regulating ACE2 receptor

A new study published in the journal Frontiers of Medicine indicated that Barrett's esophagus (BE) and gastroesophageal reflux disease (GERD) may represent novel comorbidities associated with SARS-CoV-2 disease. A previous study had estimated that in the United States, 5.6% of adults have BE, a disease where esophageal squamous mucosa gets damaged by GERD.

Researchers find a way to turn SARS-CoV-2’s virulence mechanism against itself

A recent study, currently available on the bioRxiv* preprint server, reveals that a specific region of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be targeted by antisense oligonucleotides to potently inhibit viral replication, and consequently the development of coronavirus disease (COVID-19).

Lessons from COVID-19 response during first three waves in New South Wales

Scientists from Australia have recently analyzed the public health measures adopted by the authorities during the three waves of coronavirus disease 2019 (COVID-19) pandemic in New South Wales, Australia.

Scientists develop a novel and potent SARS-CoV-2 RBD-homodimer vaccine

A recent report published in the journal Cell Discovery has described the immunogenicity and protective efficacy of a novel coronavirus disease 2019 (COVID-19) subunit vaccine candidate. The vaccine induces robust immune responses in rodents and non-human primates and protects the animals against severe disease.

The strengths and weaknesses of the spike protein in SARS-CoV-2 variants

The S protein has the ability to appropriate various conformations that are dependent on the formation of the receptor-binding domain (RBD) of its protomers.

Does Delta increase the risk of hospitalization compared with Alpha?

A team of researchers conducted a cohort study to understand the risk of hospitalization in patients with either the Delta or Alpha variants of SARS-CoV-2.
