Measles (Rubeola): A Case Of Vaccine Hesitancy And Pregnancy.

Measles (rubeola) is a highly contagious virus. Vaccination has nearly eradicated measles in the United States, yet sporadic outbreaks persist. Although the live-attenuated measles, mumps, rubella vaccine has not been found to cause fetal harm, pregnancy is considered a contraindication for the vaccine and contracting measles during pregnancy can have serious sequelae. Furthermore, lifelong immunity conferred by childhood vaccination is questionable as the vaccine's protection may wane during the childbearing years. Reluctance to vaccinate, or vaccine hesitancy, may leave a proportion of people of childbearing age unprotected. It is unlikely that many clinicians providing preconception, primary, and perinatal care have had occasion to diagnose measles. Susceptibility to infection combined with clinician inexperience may contribute to missed opportunities to halt the spread of this highly contagious, preventable illness. A case of parents' religion-based vaccine hesitancy complicating the pregnancy of their adult daughter is presented. Guidelines for screening for immunity, identifying measles in the clinical setting, and protocols for mitigating spread are reviewed.
