COVID-19 Vaxx Doses and Deaths/Mortality in Japan (All Causes, Person-year Analysis)
Note:
Graphs were created by analyzing data obtained through information disclosure requests made by residents to each municipality
Mortality rates are calculated by the person-year method, either monthly or semiannually, for each number of vaccine doses
Information on age group and vaccination date by dose for all residents was used, along with the date of death (for residents who had died)
For unvaccinated individuals, information indicating non-vaccination and the date of death (for residents who had died) was used
Age is calculated for each observation date from a reproducible virtual birthday derived from the disclosed age or age band
Age at death is calculated on the death date using the same virtual birthday
The analysis covers the period from February 2021 to June 2024
Residents who moved out during the period or had discontinuous vaccination records were excluded from the analysis
The number of analyzed individuals is after these exclusions
