Symptom narrative

MA approached nursing staff to ask about vaccination for pediatric patient, relayed that patient was due for MMR booster. Due to patient's age, MA was standing with PCP/MD and other RN, when MA asked provider to confirm if pt should get MMR or MMRV. MA asked where vaccines kept, MA retrieved vaccine and then administered to patient. After the visit, the MA approached this writer to inform that the vaccine administered was expired. This RN alerted the PM and MD of the situation, and this writer contacted vaccine management unit and DPH to report the event and receive instructions from DPH RN on next steps. This writer spoke with DPH RN this morning, who relayed that there shouldn't be any negative side effects, other than expected SE/AE of vaccine and that patient should seek booster dose within next 4 weeks. This writer called the patient's mother and relayed situation, and mother was understanding. Patient's father called back in requesting a write up of what happened, why it happened, and a statement showing that pt will have no adverse effects from this. This writer tried to explain that due to multiple parties being part of vaccine management at practice, expired vaccines were left in fridge, and staff are going to be reassigned duties to handle vaccine management. Patients parents confirmed no observation of adverse effects.
