INTRODUCTION: Vaccine-associated measles is generally not considered to be transmissible, as opposed to wild-type measles, which is one of the most highly contagious diseases. Data on contact and exposure management of vaccine-associated measles is limited, with varied approaches to such cases described in the literature.
METHODS: We report the case of a 2-year-old immunosuppressed child who developed a febrile exanthem with mild conjunctivitis 18 days after receiving the measles-mumps-rubella-varicella vaccine.
RESULTS: Given the patient's recent measles-containing vaccination while on immunosuppressive medications, consistent clinical findings, and the lack of epidemiological risk factors for wild-type infection the decision was made to treat this as a presumptive case of vaccine-associated measles virus prior to return of confirmatory genotyping results. After consultation with public health experts, contact tracing was not considered necessary. No secondary measles cases were identified, despite a large exposure potential due to lack of consistent airborne precautions during hospital admission.
DISCUSSION: This case highlights the lack of transmissibility of vaccine-associated measles in immunocompromised hosts, adding to the scant body of literature on this topic, with the potential to inform hospital infection prevention and control as well as public health management in similar situations.
