Chrissy, a healthy infant, has come to the Public Health office for her well child exam and scheduled 12-month Immunizations. She has had the recommended immunizations at 2, 4 and 6 months without any complications. She is accompanied by her mom Chera who is reluctant to have Chrissy receive the MMRV vaccine scheduled for today. Chera is unsure if she is going to have Chrissy vaccinated and expresses this concern to the nurse.
