AU TGA pregnancy category: B2
US FDA pregnancy category: B

Comments:
-Women who are pregnant or trying to become pregnant are advised to postpone vaccination until the completion of pregnancy.

Animal studies showed no adverse effects on the offspring and no effects on fertility. There are no adequate and well-controlled studies in pregnant women. Human pregnancies that occurred during clinical trials (study drug administration was delayed until resolution of pregnancy during clinical trials) had adverse event (spontaneous abortion, late fetal death, or congenital anomaly) rates that were similar in both the active drug and placebo groups.

AU TGA pregnancy category B2: Drugs which have been taken by only a limited number of pregnant women and women of childbearing age, without an increase in the frequency of malformation or other direct or indirect harmful effects on the human fetus having been observed. Studies in animals are inadequate or may be lacking, but available data show no evidence of an increased occurrence of fetal damage.

US FDA pregnancy category B: Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women.
