No concomitant medication was reported.  The co-suspect Humira concentration was reported as 40 MG/0.4 ML and formulation was reported as solution for injection in pre-filled pen. Eye exam: Report was unknown. It was unknown if she was enrolled in a COVID-19 Vaccine Trial.  No treatment information was reported.  The reporter causality for the event of deadly sick after both injections of COVID vaccine, ill, left shoulder had torn or partially torn rotator cuff, type one diabetes, two bouts of blood sugar reaction shooting up of over 500 and vomiting/could not keep food down with co-suspect Humira was no reasonable possibility. The reporter causality for the events felt horrible, tendon tear on finger of right hand, terrible headache, feverish and joint pain with co-suspect Humira was not provided.
