Q. A 30-year-old female presents to the emergency department with a painful rash on the left side of her body. She reports that the rash started a few days ago as a cluster of small bumps on her left arm, but it has now spread to her abdomen and chest. The patient also reports that she has been experiencing sharp shooting pains in the affected area for the past few days, which has been worsening. She reports a history of chickenpox during childhood. On physical examination, the rash appears as small, fluid-filled blisters in a linear pattern on her left elbow and forearm (see image). Her vital signs are within normal limits. You make a clinical diagnosis of shingles and start her on antiviral medication and pain management. She inquires about treatment for her family members. Specifically, she ask you about the effectiveness of varicella zoster immune globulin (VZIG) because she saw an advertisement on television. You inform her VZIG is contraindicated in which group of the following patient’s?
