When should a woman with a nonexistent rubella titer level during her first trimester of pregnancy receive the rubella vaccine?

A woman with a nonexistent rubella titer level during her first trimester of pregnancy should receive the rubella vaccine after delivery of the infant. This timing is crucial because administering the live attenuated rubella vaccine during pregnancy can pose risks to the developing fetus, including congenital rubella syndrome. Therefore, vaccination is recommended postpartum, ideally before the patient leaves the healthcare facility after childbirth, to ensure that she is protected before her next potential pregnancy.

Rubella vaccination is effective, and following these guidelines helps prevent complications associated with rubella infection in future pregnancies. By ensuring the vaccine is administered after delivery, healthcare providers can maintain both maternal and fetal safety.
