The Brazilian COVID-19 vaccination campaign: a modelling analysis of sociodemographic factors on uptake.

ABSTRACT:

Objective

Dose shortages delayed access to COVID-19 vaccination. We aim to characterise inequality in two-dose vaccination by sociodemographic group across Brazil.

Generalised linear regression was used to investigate the risk of death and hospitalisation by
