Inactivated vaccine BBIBP-CorV (Sinopharm; 95% (95%CI: 94%,97%)) and the mRNA vaccine BNT162b2 (Pfizer-BioNTech; 98% (95%CI: 86%,99%)) demonstrated protection against COVID-19 related hospitalizations from the Delta (B.1.617.2) variant. Ongoing efforts are necessary to target vaccine hesitancy and promote booster shots for protection against severe COVID-19 disease and arising variants of concern.

Ethnoracial groups in high-income countries have a 2-fold higher risk of SARS-CoV-2 infection, associated hospitalizations, and mortality than Whites. Migrants are an ethnoracial subset that may have worse COVID-19 outcomes due to additional barriers accessing care, but there are limited data on in-hospital outcomes. We aimed to disaggregate and compare COVID-19 associated hospital outcomes by ethnicity, immigrant status and region of birth. ⋯ Data disaggregated by region of birth identified subgroups of immigrants at increased risk of COVID-19 ICU admission, providing more actionable data for health policymakers to address health inequities.

Covaxin/BBV152 is one of the most widely used vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and one of the few vaccines used extensively in low- and middle-income countries (LMIC). ⋯ Thus, Covaxin induces an enhanced humoral immune response, with persistence till at least 12 months post-vaccination against most SARS-CoV-2 variants.
