Citizen volunteers' disclosure request and web database for post-vaccination deaths among 4 million mRNA COVID-19 vaccine recipients in Japan: A massive wave of deaths occurring months after vaccination, amplified and prolonged by frequent dosing

While mass vaccination campaigns of COVID-19 vaccines slowed after the 3rd dose in Europe and the United States, Japan continued its world-leading vaccination program, including up to eight doses by 2024. Since the start of COVID-19 vaccinations in 2021, Japan has experienced significant excess mortality. Despite government agencies holding data on vaccination status and deaths among vaccine recipients, the entire scope of potential vaccine-related harm remained unclear. Citizen volunteers collected data from municipalities nationwide, totaling 17,545,662 doses administered to 4,025,948 individuals in the retrospective cohort study. Notably, mortality rates sharply increased several months after vaccination. Furthermore, multiple doses correlated with increased mortality; each additional dose led to earlier deaths and prolonged periods of elevated mortality. The massive deaths associated with vaccination may have been overlooked until now because the majority of deaths have occurred not immediately after vaccination, but several months later. The total number of Japanese individuals who died within one year of vaccination between 2021 and 2024 was estimated to be approximately 3.89 million. While this figure does not necessarily represent the number of people who died directly from the COVID-19 vaccination, it suggests that far more lives were impacted by the vaccine than commonly believed. It raises the possibility that the COVID-19 vaccine caused accelerated aging in Japanese individuals, potentially leading to death at an earlier age than their natural lifespan.
