Vaccine, Measles

Name: VACCINE, MEASLES
Class: Vaccine
Risk Factor: CM

Fetal Risk Summary

Measles (rubeola) vaccine is a live, attenuated virus vaccine (1,2 and 3). Animal reproduction studies have not been conducted with the vaccine.

Measles occurring during pregnancy may result in significant maternal morbidity, an increased abortion rate, stillbirth, prematurity, and congenital malformations (1,2). Although a fetal risk from the vaccine has not been confirmed, the vaccine should not be used during pregnancy because fetal infection with the attenuated viruses may occur (1,2,3 and 4). The manufacturer and the American College of Obstetricians and Gynecologists lists pregnancy as a contraindication and recommend that pregnancy should be avoided for 3 months following vaccination (1,2). A shorter interval is recommended by the Centers for Disease Control and Prevention (CDC) (5). They recommend that women avoid becoming pregnant for 30 days after vaccination (5). However, no cases of congenital malformations attributable to measles vaccine virus have been reported (5).
