Havrix and Pregnancy
No studies have been conducted on pregnancy and the use of Havrix (hepatitis A vaccine), so the risks the vaccine poses to a fetus (if any) are not known. Healthcare providers believe the medication should not cause any problems, and may actually recommend that pregnant women who are especially at risk for infection with hepatitis A receive the vaccination.
Is Havrix Safe While Pregnant?Havrix® (hepatitis A vaccine) is approved to prevent hepatitis A. It is licensed for all age ranges. At this time, it is uncertain whether this vaccine is safe for use during pregnancy. However, the benefits of Havrix for preventing hepatitis A may be worth the possible risks for certain pregnant women.
What Is Pregnancy Category C?The U.S. Food and Drug Administration (FDA) uses a category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Pregnancy Category C is given to medicines that have not been studied in pregnant humans but do appear to cause harm to the fetus in animal studies.
In addition, medicines that have not been studied in any pregnant women or animals are automatically given a pregnancy Category C rating.
The effects of Havrix on a developing fetus are unknown. It is not expected to cause significant or serious problems. However, because it has not been adequately studied in pregnant women, the possibility of problems cannot be ruled out.
Healthcare providers may recommend Havrix to pregnant women who are at high risk for hepatitis A infection, such as women traveling to countries with a high prevalence of this disease.
