The paper analyzes Monkeypox virus genomes from India, identifying three subclusters within the A.2 lineage and additional APOBEC3 mutations.

The paper examines six cases of SARS-CoV-2 reinfection following primary infection and Covishield vaccination, showing reduced hybrid immunity and the need for booster doses.

This study compares IgG and neutralizing antibody responses in vaccinated and unvaccinated individuals infected with the Omicron variant of SARS-CoV-2, showing reduced neutralization against Omicron compared to earlier variants.

The paper isolates the Omicron variant from Syrian hamsters and compares its genetic changes to human clinical specimens and Vero CCL-81 cell passages.

This study evaluates immune response in Covishield vaccinated and recovered individuals against the Delta variant, finding higher protection in breakthrough cases and recovered individuals compared to single or double vaccinated groups.

This study assesses the neutralization efficacy of sera from COVID-19 recovered cases and BBV152 vaccinees against SARS-CoV-2 variants B.1.351 and B.1.617.2, showing reduced titers but still protective responses.

This study compares neutralizing antibody responses in Covishield-vaccinated individuals and COVID-19 recovered subjects against B.1 and B.1.617.1 variants, finding higher neutralization in recovered subjects.

The paper assesses the neutralizing ability of sera from BBV152 vaccinees and convalescent COVID-19 patients against B.1.617 variants.
