What if Heplisav-B or PreHevbrio is inadvertently administered during pregnancy?

There are insufficient data available to inform assessment of Heplisav-B or PreHevbrio vaccine-associated risks during pregnancy.

Dynavax has established a Heplisav-B Vaccination in Pregnancy Registry in order to understand the effect (if any) of Heplisav-B vaccination during pregnancy. Individuals who receive Heplisav-B within 28 days before pregnancy or at any time during pregnancy are encouraged to participate in the registry by calling 1-844-443-7734 (toll-free).

VBI has established a registry that monitors pregnancy outcomes in mothers exposed to PreHevbrio during pregnancy. Individuals who receive PreHevbrio during pregnancy are encouraged to contact 1-888-421-8808 (toll-free).
