New SARS-CoV-2 variant JN.1 shows increased transmissibility and immune resistance

A Japanese study published in BioRxiv explores the virological characteristics of the SARS-CoV-2 JN.1 variant, finding it has a higher effective reproductive number and stronger resistance to immunity from other variants, potentially due to the L455S spike protein mutation.

11 Dec 2023

T cells can recognize and fight the "Pirola" variant, new study suggests

In August, researchers detected a new SARS-CoV-2 "variant of concern" in patients in Israel and Denmark.

Omicron infection linked to brain structure changes in men, study finds

Study reveals that men infected with the SARS-CoV-2 Omicron variant experience changes in brain structure, including reduced gray matter thickness and subcortical nuclear volume. These findings, based on MRI data and clinical symptoms, highlight the neurological impact of Omicron infection, contributing to our understanding of COVID-19's effects on the brain.

XBB.1.5 vaccine booster shows promise against new Omicron variants in latest study

A study posted to bioRxiv reveals that the monovalent XBB.1.5 vaccine booster significantly boosts neutralizing antibodies against new SARS-CoV-2 Omicron sub-variants. The research shows that both XBB.1.5 vaccination and infection elevate neutralizing titers, with the vaccine being particularly effective in infection-naïve individuals and those previously infected with Omicron.

Half-dose Pfizer COVID booster nearly as effective as full dose with fewer side effects

Study compares the half-dose and full-dose Pfizer-BioNTech BNT162b2 COVID-19 booster in adults previously vaccinated with ChAdOx1, BBIBP-CorV, or Gam-COVID-Vac. It finds that the half-dose booster has fewer side effects and maintains similar immunogenicity, offering a viable option for booster vaccination strategies.

COVID-19 vaccines offer protection against long-term effects, study suggests

A new study in The BMJ explores how far vaccination averted PCC.

24 Nov 2023

Isolation measures during pandemic drove faster, more transmissible SARS-CoV-2 variants, study reveals

A Nature Communications study finds that isolation practices during the COVID-19 pandemic influenced the evolution of SARS-CoV-2, leading to variants with earlier, higher peak viral loads but shorter infection durations, suggesting a shift towards increased transmissibility.
