These conspiracy theories (and yes, that's what they are) are not just ridiculous, they are actually dangerous. The meme that there has been a "dramatic" increase in soccer players having heart attacks is disproved by the data. Actually, they are having heart attacks at the exact same rate as before COVID-19. You can look it up if you don't believe me.
When you spread misinformation about the vaccine, you are encouraging people not to take a simple, safe and proven therapy that will keep everybody safe. If people were to just get the vaccine, we would have already beaten COVID. I'm vaccinated and boosted, and I have had no side effects whatsoever.
