Myocarditis can cause acute symptoms such as fever, back and limb pain, fatigue, and even cardiogenic shock and sudden death in severe cases.

Myocarditis vaccination may affect the effect of the vaccine, and may also produce some adverse reactions, which will also affect the healing of myocarditis. It is recommended that patients should receive the New Crown vaccine after their myocarditis has healed. During the epidemic, it is important to protect yourself and wear a mask when going out.
