Tosin saattaa olla, että rokotetyyppi vaikuttaa myös. Tässä artikkelissa on kertomus 43-vuotiaasta terveestä kiinalaisesta maanviljelijästä, joka sai Cov-rokotteena inaktivoitua sars-2 virusta. Hänelle tuli HLH-reaktio ja tilanne hoidettiin sen diagnoosin mukaisesti . Henkilö toipui. Johtopäätöksenä toivotaan akuutin EBV tulehduksen ja muun akuutin virustulehduksen poissulkemista ennen vastaavan koronarokotuksen ottamista. Suomessa annetut rokotteet eivät ole valmistettu artikkelin kuvaamalla tavalla.

Abstract
Cases of thrombotic thrombocytopenia induced by coronavirus disease 2019 (COVID-19) vaccines have been reported recently. Herein, we describe the first case of another critical disorder, hemophagocytic lymphohistiocytosis (HLH), in a healthy individual after COVID-19 vaccination. A 43-year-old Chinese farmer developed malaise, vomiting, and persistent high fever (up to 39.7 °C) shortly after receiving the first dose of the inactivated SARS-CoV-2 vaccine. The initial evaluation showed pancytopenia (neutrophil count, 0.70 × 109/L; hemoglobin, 113 g/L; platelet, 27 × 109/L), elevated triglyceride (2.43 mmol/L), and decreased fibrinogen (1.41 g/L). Further tests showed high serum ferritin levels (8140.4 μg/L), low NK cell cytotoxicity (50.13%-60.83%), and positive tests for Epstein-Barr virus (EBV) DNA. Hemophagocytosis was observed in the bone marrow. Therefore, HLH was confirmed, and dexamethasone acetate (10 mg/day) was immediately prescribed without etoposide. Signs and abnormal laboratory results resolved gradually, and the patient was discharged. HLH is a life-threatening hyperinflammatory syndrome caused by aberrantly activated macrophages and cytotoxic T cells, which may rapidly progress to terminal multiple organ failure. In this case, HLH was induced by the COVID-19 vaccination immuno-stimulation on a chronic EBV infection background. This report indicates that it is crucial to exclude the presence of active EBV infection or other common viruses before COVID-19 vaccination.
