  1. The frequency and rate per 1,000 person-years of severe COVID-19 outcomes (COVID-19-related hospitalization or death) was calculated. aRRs were estimated adjusting for all confounders, including age, sex, Scottish Index of Multiple Deprivation (SIMD), time since receiving the second dose of vaccine, number of pre-existing comorbidities, the gap between vaccine doses, previous history of SARS-CoV-2 infection and calendar time. Where the BMI was missing, it was imputed using ordinary least squares regression with all other independent variables included as predictors (BMI (imputed)).
