| dc.description.abstract | The novel mRNA vaccinations against COVID-19 are gaining worldwide attention for their efficacy, as well as the diagnosis of some post-vaccination-reported adverse reactions. In this state-of-the-art review article, we present the current evidence regarding mainly the diagnosis of spontaneous allergic reactions, the skin occurrences, the vascular, blood, endocrine and heart events, the respiratory reports, the gastrointestinal, hepatic and kidney events, the reproductive and pregnancy issues and the muscle events, as well as the ear, eye, neurologic and psychiatric events following mRNA vaccination against COVID-19. We further present some evidence regarding the mRNA strategies and we discuss our expert opinion on the knowns and the unknowns towards the topic. © 2022 by the authors.
