Israel’s health ministry has reported a link between the Pfizer Covid-19 vaccine and a number of myocarditis cases in the country. The majority of the cases were found to have occurred in men aged between 16 and 30 years. Myocarditis is a condition characterised by an inflammation of the heart muscle that can be caused due to a viral infection or reaction to a medication. Pfizer said in a statement that it was aware of the observations made by the Israeli health ministry, but that no causal link between its vaccine and the cases of myocarditis had been established.
