The virus has evolved to get around vaccine induced antibodies, and those from prior infections. It is better at suppressing the immune system and persisting in our organs for months. Most young adults didn't get vaccinated in the U.S. Only 15% took the latest booster. COVID is rampant. What is the more likely cause? Think about that.

A side note, if vax was that bad for heart then I how did I completely avoid any injury? 4 shots, mild autoimmune reaction after 4th passed me off but took to soon. Had echocardiogram and stress test on heart last week. Everything is normal and healthy.

People reinfected with COVID repeatedly, not so healthy.
