Art of prevention: Our approach to the measles-mumps-rubella vaccine in adult patients vaccinated against measles before 1968 on biologic therapy for the treatment of psoriasis.

Background: In response to the evolving measles epidemic in the United States, the Centers for Disease Control and Prevention recommended that some adults be revaccinated against measles because they may have inadequate immunity against the virus. Patients receiving biologic medications for psoriasis face a clinical dilemma because they may be at an increased risk of developing severe measles; however, vaccination with the measles-mumps-rubella (MMR) vaccine is not recommended for those on biologic therapy according to the American Academy of Dermatology-National Psoriasis Foundation guidelines.

Objectives: This study aimed to review available research on the safety and efficacy of live-attenuated vaccines in individuals receiving biologic therapy for psoriasis and to discuss our approach to vaccinating individuals on biologic agents for psoriasis with the MMR vaccine.
