Vaccine, Tularemia in Pregnancy and Breastfeeding

Risk Factor: C
Class: Serums, toxoids, and vaccines / Vaccines

Fetal Risk Summary

Tularemia vaccine is a live, attenuated bacteria vaccine (1,2). Tularemia is a serious infectious disease occurring primarily in laboratory personnel, rabbit handlers, and forest workers (1). The risk to the fetus from the vaccine is unknown. One report described vaccination in a woman early in the 1st trimester with transplacental passage of antibodies (2,3). No adverse effects were observed in the term infant or at 1-year follow-up. Because tularemia is a severe disease, preexposure prophylaxis of indicated persons should occur regardless of pregnancy (1).
