Utter BS. No such study exists. There is NO peer-reviewed Japanese study of ~20 million people showing all excess deaths exclusively in the vaccinated, zero in the unvaccinated, or mortality peaks ~100 days after boosters. The claim traces to a non-scientific activist livestream (featuring Yasufumi Murakami and anti-mRNA groups) about a flawed, incomplete database, not a rigorous study. Key problems with that “data”: -It records vaccine doses, not uniquely identified people (numbers like 18–21 million are inflated or actually misstated). -Covers only a tiny fraction of Japan’s vaccinations (~5%, limited municipalities). -Lacks proper unvaccinated controls, age/health adjustments, or causes of death. -Maybe some correlation at best, zero evidence of causation. Real excess mortality in Japan rose during the pandemic (especially post-Omicron) for multiple reasons. Authors of actual published analyses have explicitly rejected claims that their work shows vaccine-driven death spikes. High vaccination rates (especially among elderly) mean most natural deaths occur in vaccinated people by basic arithmetic, not because shots kill. Professor Clancy is an emeritus academic who has become a prominent mRNA skeptic appearing on platforms known for amplifying such claims. Large, controlled studies and surveillance data consistently show COVID vaccines reduced severe disease and deaths, with no population-level excess mortality signal attributable to them. CONCLUSION: UTTER BS!
