Nurse was not appropriately trained on pfizer vaccine administration; up until that point she had only given moderna which does not need to be diluted. Patient did not experience any significant known untoward effects. It was also reported that patient provided information regarding the reported adverse events with the use of the product and considered the Pfizer product had a causal effect to the adverse event. There was no specific relevant test for thromboembolic events with thrombocytopenia. Patients wife (who was also a pharmacist) was in the vaccine room with him, she was getting her booster at the same time. She realized about 2 seconds too late that the vaccine was not diluted by the nurse. The nurse opened the vial and aspirated 0.3 ml of straight undiluted vaccine and administered it to him. The error was realized immediately after injection. He had only mild symptoms- fatigue starting about 8 hours after the injection which lasted about 24 hours total. Upon waking the next day, he had arm soreness and some nausea but that resolved eventually.
