Ad5-nCoV vaccine safe and effective against symptomatic, severe COVID-19, trials shows

One dose of Ad5-nCoV (Convidecia), a COVID-19 vaccine developed in China, is 57.5% effective against symptomatic COVID-19 and 91.7% effective against severe COVID-19 disease beginning 28 days postvaccination, according to a phase 3 randomized controlled trial published in The Lancet.

CDC releases updated guidance for contingency and crisis management in healthcare settings

With the growing number of COVID-19 cases from the Omicron variant, and consistent with current understanding of the disease trajectory, CDC is releasing updated guidance for isolation and quarantine for healthcare workers, decreasing their isolation time after infection with COVID-19.

Omicron has enhanced infectivity that is only weakly neutralized by vaccination or prior infection

Scientists used virus-like particles and found that Omicron showed increased infectivity, relative to the B.1 and B.1.1 strains, which was similar to the Delta variant.

Exploring why children have milder COVID-19 infections compared to adults

A new study has revealed that an activated pre-exposure innate interferon response in airways together with significantly reduced systemic interferon-stimulated populations are associated with relatively milder severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in children.

Exploring immunity and severe disease caused by the SARS-CoV-2 Omicron variant

A new study describes the findings of a seroprevalence survey intended to establish the infection rates and the incidence of severe COVID-19 through December 15, 2021, in Gauteng, a crowded province that compresses a quarter of the country’s people into less than 2% of its area.

Assessing the clinical severity of the SARS-CoV-2 Omicron variant

A recent preprint examines the proportion of Omicron infection and the risk of severe disease with this variant of SARS-CoV-2.

Study reports that children develop sustained cross-reactive adaptive immunity against coronaviruses

A new study shows that both antibody and cellular arms of the adaptive immune response against SARS-CoV-2 are displayed strong, sustained, and cross-reactive against other coronaviruses, in young children than the immune responses in adults.

Boceprevir-based molecules show high antiviral potency against SARS-CoV-2

In a study posted to the bioRxiv* pre-print server, a team of researchers conducted a structure-activity relationship study of boceprevir-based molecules to find antiviral drug candidates targeting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) protease MPro.
