Aim: A number of cases of SARS-CoV-2-related myocarditis have been reported since the outbreak of the Covid-19 pandemia, with autoimmune-mediated damage due to molecular mimicry proposed as the virus’ direct mechanism of injury. After commencing with a worldwide mass vaccination program, there have also been reports of myocarditis in the context of Covid-19 immunization. However, myocarditis is still not recognized as a potential side effect of the AZD1222 (ChAdOx1-S recombinant) vaccine administration by the health authorities.

Methods: In this article we report a case of myocarditis and further complications after vaccination for Covid-19 using the AZD1222 vaccine.

Conclusion: Even though it is hard to demonstrate the etiology of acute myocarditis, considering the cases reported around the world, the temporal association, the absence of other plausible causes, and the serological pattern described, it seems reasonable to assume that there is a genuine possibility of myocarditis being a side effect of AZD1222 vaccine administration.

Keywords: myocarditis, Covid-19, SARS-CoV-2, vaccination, immunization, thrombocytopenia, vaccine, AZD1222, mRNA vaccine
