evidence: Table 1 Characteristics of the study population for deaths after vaccination, young people aged 12-29, resident in England, who died between 8 December 2020 − 25 May 2022 (registered by 8 June 2022) for ONS registered deaths, and who died 8 December 2020 − 31 March 2022 for HES hospital deaths [...] Fig. 2: Relative incidence of cardiac and all-cause death in the risk period after vaccination, compared to the baseline period, by sex, age group and vaccine vector. [...] For all three analyses of death after vaccination, varying defined lengths of risk period were consistent with the main findings in remaining below or not significantly different to 1 (Supplementary Fig. 7). For analyses of deaths after a positive SARS-CoV-2 test for individuals unvaccinated at the date of test registration, estimates of relative incidence of all-cause death were greater for shorter risk period definitions, particularly for hospital deaths. While convergence towards one was observed as the defined risk period was increased, complete convergence was not observed, with the relative incidence appearing to stabilise above one for all-cause and cardiac deaths (Supplementary Fig. 7A). For analyses of deaths after a positive SARS-CoV-2 test for individuals vaccinated at date of test registration (Supplementary Fig. 8B), estimates of the relative incidence of all-cause registered the death and all-cause hospital death were greater for shorter risk period definitions and converged to 1 as the risk period was increased.
