Symptom narrative

The patient arrived at the clinic for immunization after the provider reviewed their vaccination schedule and determined that they were due for four vaccines. The medical assistant administered the vaccines after confirming with the provider. However, she later realized that the patient received the MMRV vaccine instead of the separate MMR and varicella vaccines. The patient received two doses of varicella at the same time. The medical assistant spoke with the patient's father to inform him of the incident and to ask if the child had experienced any adverse effects. The father denied any adverse reaction.
