Worldwide, there have been very rare cases of inflammation of the heart called myocarditis or pericarditis reported after some vaccinations. These cases have been seen mostly in younger men within several days after vaccination. Most of these people recovered and felt better following rest and simple treatments.
You should seek medical advice urgently if, after vaccination, you experience:
- chest pain
- shortness of breath
- feelings of having a fast-beating, fluttering, or pounding heart
