Heart events are not secret. They have been reported since the beginning by the federal government. https://health-infobase.canada.ca/covid-19/vaccine-safety/

Look at Table 1 and select "Rate" from the drop down menu. You'll see that cardiac arrests and failures, heart attacks, and inflammation of the heart muscle and lining - all together - are running at 2 incidents per 100,000 doses of the vaccine. Actual fatalities (cardiac failures) are running at 0.05 per 100,000. That's 1 in 2 million.

Compare that to the fact that - in round numbers - one person dies for every 50 that test positive for the virus.

Some people seem to feel that that's OK because it's usually someone older. That reasoning puzzles me.
