COVID-19 vaccine: four years later, the list of persistent symptoms keeps growing

In addition, all vaccines significantly increased the risk of myocarditis and pericarditis— inflammations of the myocardium (the muscle responsible for heart contraction and for circulating blood throughout the body).
“Other issues have been identified that require further research,” notes the journal.

The researchers emphasize that more investigation is needed to determine the relationship between the vaccine and these side effects.

Conclusion

Faced with this alarming situation, COVID-19 vaccines were developed urgently.
After nearly five years of observation and analysis, we now have a better understanding of the side effects of the different vaccines that were administered.
