The claim
新型コロナワクチン接種開始後38万人が超過死亡
Original review summary
The review says the claim of more than 380,000 excess deaths differs substantially from the National Institute of Infectious Diseases’ estimates for May 2021 through October 2023. It also cautions that excess-death estimates do not identify causes and do not establish that deaths were caused by vaccination.[S1]
