In addition, all vaccines showed an increased risk of myocarditis and pericarditis — inflammations of the heart muscle or its surrounding tissue — although these events remain rare.
“Other issues have been identified that require further research,” the journal notes.
Researchers emphasize that additional investigation is necessary to fully understand the relationship between vaccination and these adverse events.
Conclusion
COVID-19 vaccines were developed under urgent circumstances during a global health crisis.
After nearly five years of real-world data and scientific analysis, we now have a clearer — though still evolving — understanding of the possible side effects associated with these vaccines.
In December 2019, a new virus appeared in China and rapidly spread worldwide, raising global concerns — including from the World Health Organization (WHO). This highly contagious infectious disease, later named COVID-19, led to an unprecedented global pandemic.
