Some variants of SARS-CoV-2 are associated with increased transmissibility, disease severity or decreased vaccine effectiveness (VE). In this population-based cohort study (n = 4,204,859), the Delta variant was identified in 5,430 (0.13%) individuals, whom 84 were admitted to hospital. VE against laboratory confirmed infection 22.4% among partly vaccinated (95% confidence interval (CI): 17.0−27.4) and 64.6% CI: 60.6−68.2) fully compared 54.5% 50.4−58.3) 84.4% (95%CI: 81.8−86.5) Alpha variant.
