title: Congenital malformations and oral poliovirus vaccination during pregnancy.
abstract: In February, 1985, mass vaccination with live oral poliovirus vaccine (OPV) was started during a poliomyelitis outbreak in Finland. Pregnant women were advised to take the vaccination. Judged as the rate of reported malformations, OPV during early pregnancy had no harmful effects on fetal development.
