DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): In May 2023, White blood cell count: High.     For mRNA-1273 BIVALENT .222 (MODERNA COVID-19 VACCINE, BIVALENT (ORIGINAL AND OMICRON BA.4/BA.5)) (Unknown), the reporter did not provide any causality assessments.   No concomitant medication was reported.  Doctors found his white count high and he was diagnosed with SEPSIS but then they couldn´t find any infection, he didn´t have SEPSIS. Doctors were blaming the vaccine. The caller stated her husband was not sick before the Covid vaccine. That was bringing him down fast. He was then diagnosed with a heart condition: ACIP.

Company comment:  This is a spontaneous case concerning a 74-year-old, male patient with Chronic obstructive pulmonary disease, previously vaccinated with 5 doses of mRNA-1273 .222 vaccine, who experienced the unexpected serious (Hospitalization) events of Cardiac disorder, dyspnoea, tremor and feeling cold. The events occurred about 10 days after the administration of mRNA-1273 .222 (Original/Omicron BA.4/5) vaccine, used as a sixth dose.  Patient developed uncontrollable shaking, feeling as freezing and difficult breathing. A blood test revealed white blood cells high which initially lead to a diagnosis of sepsis, but later it was ruled out and now diagnosed with a heart condition which was not specified. No further information on clinical course, investigations and treatment received was available in the report. Patient medical condition of COPD is a confounder for the events. The benefit-risk relationship of mRNA-1273 .222 (Original/Omicron BA.4/5) Vaccine is not affected by this report.
