Symptom narrative

Patient was in clinic for scheduled visit and was due for vaccines. Patient had a shot record with previous MMR and Varicella vaccines given, but shown as invalid on shot record, so another MMR and varicella was due. LPN and CSM and 3rd nurse discussed and reviewed chart vs. Web shot record. Determined patient needed MMR and varicella. Patient received MMRV instead of MMR and varicella separately. On Thursday, 8/14, became apparent that a vaccine error was made. Spoke to the CS and VFC rep and discussed no adverse effects expected from error. On Friday, CS called vaccine manufacturer who confirmed the same. Parent contacted, incident reporting entered, re-education with staff addressed, label added to Proquad box for age alert.
