PREGNANCY SUMMARY

No apparent embryo or fetal harm was observed in four pregnancies inadvertently exposed to the vaccine. However, because naturally occurring infections with adenoviruses have been associated with fetal harm, the vaccine is contraindicated in pregnancy. Animal reproduction studies have not been conducted. If a pregnant woman receives the vaccine or becomes pregnant within 6 weeks following vaccination, clinicians are encouraged to report the exposure to the Adenovirus Pregnancy Registry by calling 1-866-790-4549 (1).
