title: Immunizing the pregnant woman. Risks versus benefits.
abstract: No substance should be administered unnecessarily during pregnancy. However, when a pregnant woman is not immune to serious disease, the risk of maternal and fetal infection must be weighed against the risk of vaccination. Whenever possible, an inactivated (killed) vaccine should be selected and immunization delayed until the second trimester. Only rarely is an attenuated (live) vaccine indicated.
