If you are interested, Eric Topol's newsletter has more detailed information about COVID and the ⬆️ risk of heart attack and stroke. He goes through 6 studies.
My take away is that the risk of a heart attack or stroke in an unvaccinated person is *very roughly* ~2x compared to someone who hasn't been infected, & in a vaccinated person who's been infected, it's ~1.4x compared to someone who has not been infected.
I encourage you to read the whole thing!
