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

Animal studies do not indicate direct or indirect harm to the fetus. There are no controlled data in human pregnancy. There is no convincing evidence of fetal risk from immunization of pregnant women using an inactivated bacterial vaccine.

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 C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
