We would like to share ideas on the publication ‘Myocarditis following rAd26 and rAd5 vector‐based COVID‐19 vaccine: case report’.
Naghashzadeh et al. concluded that ‘endomyocardial biopsy proved lymphocytic myocarditis such that the patient was successfully treated with immunosuppressive and guideline‐directed medical treatment’.
We agree that the COVID‐19 vaccination has the potential to cause side effects. The patient in this case developed a heart condition,
which might or could not be related to COVID‐19 vaccine. It's difficult to draw a definitive judgement because there's no information on the patient's immunological condition prior to immunization. A concomitant medical complication in a vaccination recipient is possible. Dengue fever, for example, is a potentially concomitant medical issue that can cause myocarditis in COVID‐19 vaccine recipients.
Finally, we agree that the recommended immunosuppression is a good choice for patient management and that it could be used whether or not the COVID‐19 vaccine is the cause of myocarditis.
