Local and distal involution of recalcitrant warts after a single intralesional dose of measles, mumps, and rubella vaccine

Abstract

Verruca vulgaris is a prevalent childhood condition, but treatments are often poorly tolerated. Early treatment is preferable because delays increase the probability of pain, disfigurement, and failed eradication. However, typical treatments require multiple sessions without promising cure. We describe the use of a single intralesional treatment with the measles, mumps, and rubella (MMR) vaccine to successfully eliminate both local and distant recalcitrant warts as well as the proposed mechanism of this method. There are no other known reports of complete wart regression at distant untreated sites after a single intralesional MMR treatment.
