                Pregnancy & Lactation

                Pregnancy

                There are no adequate and well-controlled studies in pregnant females

                Available human data administered to pregnant individuals do not establish the presence or absence of vaccine-associated risks in pregnancy

                NOTE: Available data on BioThrax (anthrax vaccine adsorbed), administered to pregnant individuals are relevant because both vaccines contain the same active ingredient and are manufactured similarly

                Lactation

                Unknown whether vaccine is excreted in human milk

                Human data are not available to assess the impact of the vaccine on milk production, its presence in breast milk, or its effects on breastfed children

                Pregnancy Categories

                A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

                B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

                C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

                D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

                X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

                NA: Information not available.
