Rubella, rubeola, and mumps in pregnant women: susceptibilities and strategies for testing and vaccinating.

Objective: To estimate rubella, rubeola, and mumps (MMR) susceptibilities in pregnant women and determine the percentage not immune to rubeola or mumps, depending on rubella immunity status. A secondary objective was to assess costs of vaccination and testing programs aimed at eliminating these viral susceptibilities to determine an optimal strategy.

Methods: This was an observational study of women presenting for prenatal care.
