Alpha variant of SARS-CoV-2 evolved mutations to evade the immune system

The Alpha variant of SARS-CoV-2-;the first "variant of concern"-;evolved mutations that allowed it to more efficiently suppress the immune system's early response to infection, according to a new study led by scientists at the University of California, San Francisco's Quantitative Biosciences Institute and University College London.

Pfizer-BioNTech booster shot may offer better immunity than a two-dose regimen

A new study suggests that the immune response against severe acute respiratory syndrome coronavirus 2 is greater with a three-dose regimen than a two-dose regimen.

New study provides a mutational analysis of SARS-CoV-2

A new study investigates mutational waves in structural and non-structural protein evolutions of SARS-CoV-2 to better understand the virus’s evolution and epidemiology.

Laws shield hospitals from families who believe loved ones contracted covid as patients

After Amanda Wilson lost her son, Braden, 15, to covid-19 in early 2021, she tried to honor his memory. She put up a lending library box in his name. She plans to give the money she saved for his college education to other teens who love the arts and technology.

Children with pre-existing immunity to common cold demonstrate better protection against COVID-19

New data shows that, compared to adults, children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) preferentially activate pre-existing acquired immunity to prevalent common cold coronaviruses that cross-react with SARS-CoV-2 and protect them from severe disease.

SARS-CoV-2 spreads through cell-to-cell transmission, study finds

The virus that causes COVID-19 has adopted some stealth moves to stay alive and kicking, and one secret to its success is hiding from the immune system by spreading through cell-to-cell transmission, a new study has found.

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.

Allele-specific RT-qPCR assay to identify SARS-CoV-2 Omicron variant in wastewater

Researchers develop a new allele-specific RT-qPCR to detect the SARS-CoV-2 Omicron variant in wastewater.

Children produce a much more robust antibody response to a SARS-CoV-2 infection than 18+

Scientists compared receptor binding domain antibodies and SARS-CoV-2 neutralizing antibodies in children and adults.

23 Dec 2021

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.

Researchers report loss of antibody potency against SARS-CoV-2 Omicron variant

Researchers find that vaccine-mediated protection against SARS-CoV-2 is significantly reduced against the Omicron variant.

Spatiotemporal patterns of Delta variant progression and its associated health interventions

In a new study, researchers adopted a prospective space-time scan method to conduct spatiotemporal analysis at the district level in the seven selected countries in SEA from June 2021 to October 2021.

23 Dec 2021

Impact of the rapid spread of the SARS-CoV-2 Omicron variant in Southern Africa

A new study has focused on the genomic profile and early transmission dynamics of Omicron. This study revealed the dominance of the Omicron variant in regions with high levels of population immunity.

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.
