SARS-CoV-2 infection induces robust and cross-reactive immune responses in children

Researchers compare the convalescent humoral and cellular immune responses between children and adults infected with SARS-CoV-2.

Study highlights importance of positive and negative selection in evolution of SARS-CoV-2 variants

Researchers from the University of Colorado Anschutz Medical Campus have been investigating the changes imparted on the Gamma variant by three RBD mutations.

An evaluation of the association between COVID vaccination and myocarditis in 42 million people aged 13 or older

A new study posted to the medRxiv* pre-print server included individuals over 13 years of age receiving the third vaccine dose to further evaluate the association between myocarditis and COVID-19 vaccination or infection. The study took place from December 1, 2020, to November 15, 2021.

SARS-CoV-2 Omicron variant neutralized by third BNT162b2 booster shot

A new preprint* research paper under consideration at Nature Portfolio Journal assesses the susceptibility of the Omicron variant to neutralizing antibody response after booster immunization.

Pre-existing immunity against influenza can lower SARS-CoV-2 infection burden and spread

A recent study by a team of European researchers demonstrated how antibodies induced by currently circulating influenza A H1N1 strains can cross-react with the important part of the SARS-CoV-2 spike glycoprotein that interacts with the human cell receptor. Their paper is currently available on the medRxiv* preprint server while it undergoes peer review.

Third BNT162b2 dose effectively neutralizes SARS-CoV-2 Omicron pseudovirus

The findings reveal that the Omicron neutralizing titers induced by the third vaccine dose are comparable to that achieved against the original Wuhan strain (wild-type SARS-CoV-2) by the two-dose regimen. The study is currently available on the medRxiv* preprint server while awaiting peer review.

28 Dec 2021

New report on 1.23 million breakthrough symptomatic SARS-CoV-2 infections by vaccine

A new research letter evaluates whether the estimated vaccine effectiveness changes against infection over time.

28 Dec 2021

Study suggests spike mutation makes SARS-CoV-2 Omicron milder

The Omicron spike is relatively poorly cleaved and impaired in mediating cell-cell fusion and syncytia formation, contrary to predictions.

28 Dec 2021

Pfizer vaccine associated with lower risk of SARS-CoV-2 infection and hospitalization in middle-aged adults

New findings suggest that the Pfizer-BioNTech mRNA COVID-19 vaccines provide extra protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) than AstraZeneca.

24 Dec 2021

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.

24 Dec 2021

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.

24 Dec 2021

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.

24 Dec 2021

Cryo-EM of Omicron variant reveals antibody evasion by spike-ACE2 complex

Researchers compare the obtained binding affinities to wild-type and Delta spike proteins to determine the impact of Omicron mutations.

23 Dec 2021

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.

23 Dec 2021

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.

23 Dec 2021

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.

23 Dec 2021

Coinfection of SARS-CoV-2 and human rhinovirus associated with more severe health outcomes

Researchers discuss the incidence and effect of coinfections with SARS-CoV-2 and human rhinovirus.

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.

23 Dec 2021

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.
