Conclusion
Humankind and the entire world are still suffering from the third
coronavirus infection (SARS-CoV-2), causing severe acute respiratory
syndrome and bringing countless morbidity, mortality, and a great
economic disaster. With the new Delta andOmicron variants of this
coronavirus, more preventive measures and procedures, including more
vaccinations for children and adolescents, are crucial and highly
recommended to reduce the transmission, hospitalization, and adverse
clinical outcomes. Although we found good outcomes and statistically
significant associations in symptoms between vaccinated and
non-vaccinated pediatrics, more studies are still crucial to understand
the specific etiology further underlying post-vaccination, particularly
myocarditis, psychological impact, and other
cardiac clinical symptoms on children and adolescents after receiving
the BioNTech-Pfizer vaccine.
