Israel’s Ministry of Health by March 2021 identified a nearly 1,000% increase in the risk of myocarditis associated with the second dose of the COVID-19 mRNA shot, according to documents obtained via a Freedom of Information Act (FOIA) request.

The documents, which were shared with Children’s Health Defense (CHD) last week, also include emails between top officials at U.S. public health agencies showing that Israel’s Ministry of Health contacted them about myocarditis related to the shots as early as Feb. 28, 2021.

Ministry of Health Deputy Director Roee Singer informed the Centers for Disease Control and Prevention (CDC) that the health ministry had concerns about “a large number of myocarditis and pericarditis cases in young individuals” following the Pfizer shot and sought to discuss those concerns with the CDC.
