9. Myocarditis

Of the vaccine side effects, one of the more serious is swelling of the heart muscle, called myocarditis. This primarily affects young males who receive one of the mRNA vaccines. Usually, myocarditis causes shortness of breath, chest pain, and fatigue. Severe myocarditis can weaken the heart and limit blood flow, leading to a heart attack or stroke.

However, in all major reported cases of vaccine-related myocarditis, symptoms resolved within several days and no complications developed.
