Encephalitis, myocarditis, and thrombocytopenia after COVID-19 mRNA vaccination: Clinical and pathophysiological considerations

COVID-19 vaccination has been associated with rare neurological, cardiac and hematological complications but their causal relationship is not yet fully established. We have read with interest the paper published in Journal of Neuroimmunology (Asaduzzaman et al., 2022) concerning, a 15-year-old girl who developed the following symptomatology after the second dose of Pfizer BioNTech (BNT162b2) COVID-19 vaccine: Fever and diarrhea 1  day after receiving the vaccine, marked thrombocytopenia during the initial blood count examination, symptoms and signs suggesting encephalopathy such as carpopedal spasm in both hands, altered consciousness leading to unconsciousness and attacks of convulsions well responding to methylprednisolo ne injections.
