Israel Sees Probable Link Between Pfizer Vaccine and Rare Myocarditis Cases JERUSALEM—Israel’s Health Ministry said on Tuesday it had found the small number of heart inflammation cases observed mainly in young men who received Pfizer’s COVID-19 vaccine in Israel were likely linked to their vaccination. Pfizer has said it has not observed a higher rate of the condition, known as myocarditis, than would normally be expected in the general population. In Israel, 275 cases of myocarditis were reported between December 2020 and May 2021 among more than 5 million vaccinated people, the ministry said in disclosing the findings of a study it commissioned to examine the matter.
