Complete Genome Sequencing and Molecular Characterization of Indigenous Enterovirus A71 Genogroups D and G of India

The paper characterizes two indigenous EV-A71 genogroups (D and G) from India through genome sequencing and phylogenetic analysis, revealing their distinct evolutionary paths and geographic restriction.

Comparable neutralization of SARS-CoV-2 Delta AY.1 and Delta in individuals sera vaccinated with BBV152

The paper evaluates the neutralizing activity of sera from vaccinated and recovered individuals against SARS-CoV-2 Delta, Delta AY.1, and B.1.617.3 variants, finding reduced but still effective neutralization.

SARS-CoV-2 Delta variant pathogenesis and host response in Syrian hamsters

This study compares the pathogenicity and host response of SARS-CoV-2 Delta and B.1.617.3 variants with B.1 in Syrian hamsters, finding increased disease severity and transmission potential for Delta.

Convergent evolution of SARS-CoV-2 spike mutations, L452R, E484Q and P681R, in the second wave of COVID-19 in Maharashtra, India

The paper analyzes spike protein mutations in SARS-CoV-2 variants from Maharashtra, India, identifying lineage B.1.617 with mutations linked to increased transmissibility and reduced antibody neutralization.

Neutralization of UK-variant VUI-202012/01 with COVAXIN vaccinated human serum

Sera from 26 BBV152/COVAXIN recipients neutralised the UK variant about as well as a heterologous strain in plaque reduction tests, arguing against escape from vaccine-induced antibodies.
