ABSTRACT
To assess the real-world impact of vaccines on COVID-19 related outcomes, we analysed data from over 7 million recipients of at least one COVID-19 vaccine dose in Italy. Taking 0-14 days post-first dose as reference, the SARS-CoV-2 infection risk subsequently decreased, reaching a reduction by 78% (incidence rate ratios (IRR) 0.22; 95% CI 0.21-0.24) 43-49 days post-first dose. Similarly, hospitalisation and death risks decreased, with 89% (IRR 0.11; 95% CI 0.09-0.15) and 93% (IRR 0.07; 95% CI 0.04-0.11) reductions 36-42 days post-first dose. Our results support ongoing vaccination campaigns.
