Vaccine-related myocarditis is not unique to the mRNA vaccines; myocarditis can also occur after other vaccines,27,28 including non–mRNA COVID-19 vaccines, such as influenza and smallpox vaccines. Therefore, it is possible that circulating spike is a biomarker of immune dysregulation leading to myocarditis rather than a causal agent.
Getting naturally infected with COVID might be protective if you later get the vaccine. It might decrease your chances of vaccine-induced myocarditis.
