Exercise performance in vaccinated and unvaccinated individuals previously infected with SARS-CoV-2

A cross-sectional report from Israel demonstrated the protective effect of BNT162b2 mRNA vaccine (Pfizer–BioNTech) even after mild to moderate COVID-19).

SARS-CoV-2 spike T cell responses from vaccines or infection remain robust against Omicron

In a new study, a team of researchers from multi-national institutions discovered that 70-80% of CD4 and CD8 T cell responses to spike were consistent across research groups. Moreover, although having far more mutations, the magnitude of Omicron cross-reactive T cells was comparable to that of the Beta and Delta variants.

SARS-CoV-2 Omicron variant highly resistant to vaccine-elicited and therapeutic antibodies

Researchers analyzed convalescent sera and sera from immunized individuals to demonstrate the evasion of antibodies by the SARS-CoV-2 Omicron variant.

Omicron infection induces cross-reactive immune responses

New research revealed that vaccine-breakthrough infections might elicit cross-reactive bNAbs against all variants of concern.

P323L mutations in SARS-CoV-2 are highly predictive of the emergence of new variants

In a new study, findings suggest that in some cases, tracking the distribution and frequency of SARS-CoV-2 minor variant genomes at a population level would help in predicting the emergence of a new dominant viral genome sequence.

COVID mRNA vaccines show diminished neutralization responses against Omicron

Researchers report an overview of antibody neutralization by all currently approved vaccines against the SARS-CoV-2 Omicron, Beta, and Delta VOCs.

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.

T-cell response to Omicron after an mRNA COVID vaccine booster

In a recent prospective observational study posted to the medRxiv* preprint server, researchers determined Omicron variant-associated T cell responses before and after a third dose of messenger ribonucleic acid (mRNA) vaccination against coronavirus disease (COVID-19) in anti-CD20-treated multiple sclerosis (MS) patients.

22 Dec 2021

More breakthrough infections but less severe COVID-19 with Omicron

In a recent study posted to the bioRxiv* pre-print server, an international team of researchers reported the occurrence of coronavirus disease 2019 (COVID-19) breakthrough infections (BTIs) among health care workers (HCWs) participating in a phase III vaccine trial in Sisonke, South Africa.
