LIVE SCIENCE: Researchers in Israel say they've found a possible link between the Pfizer-BioNTech COVID-19 vaccine and cases of heart inflammation in young men ages 16 to 30, according to a report submitted this week to the country's Ministry of Health.
The report concluded that around 1 in 5,000 men who receive the vaccine may experience this side effect, known as myocarditis, which is higher than the rate seen for the whole vaccinated population during that time period, which was 1 in 50,000.
So far, the data isn't yet strong enough to prove that the vaccine caused these cases — experts say there are a number of factors that make it difficult to definitively tie the vaccine to heart inflammation, a link that's also being investigated in the United States. » | Rachael Rettner, Senior Writer | Saturday, June 5, 2021
