Clinical narrative: leukemia; It changed very much not only mental, not as toxic and stuff but had this now; This spontaneous case was reported by a consumer and describes the occurrence of LEUKAEMIA (leukemia) in a male patient of an unknown age who received mRNA-1273 BIVALENT (MODERNA COVID-19 VACCINE, BIVALENT (ORIGINAL AND OMICRON BA.4/BA.5)) for COVID-19 prophylaxis. The occurrence of additional non-serious events is detailed below.     No Medical History information was reported.

On an unknown date, the patient experienced LEUKAEMIA (leukemia) (seriousness criterion medically significant) and IMMUNISATION REACTION (It changed very much not only mental, not as toxic and stuff but had this now). At the time of the report, LEUKAEMIA (leukemia) and IMMUNISATION REACTION (It changed very much not only mental, not as toxic and stuff but had this now) outcome was unknown.            Concomitant product use was not provided by the reporter.   The reporter stated that, after the vaccination with the mRNA, it changed patient and parents very much.
