Q&A: Is the hepatitis B vaccine safe during pregnancy?

Just because you're pregnant doesn't mean that you shouldn't finish off your round of vaccinations. Protection is best accomplished with a full series, so keep on schedule and get the third injection. This not only protects you, but your baby who will be at considerable risk should you ever contract hepatitis—acutely or as a silent carrier. This disease can cause hepatitis and increase the risks of liver cancer in you and your children if you're exposed.

You should be aware however, the the Centers for Disease Control and Prevention (CDC) says that you should let your health care provider know that you're pregnant and that you're finishing off your vaccinations for hep B. In their words, "Pregnant women who need protection from HBV infection may be vaccinated."
