Pregnancy and Immunization

Immunization provides protection against disease that can cause serious harm. An expecting mother who is immunized not only protects herself but also passes on the protection to her baby. The protection continues to be shared with the baby through breastfeeding. Staying up to date on your immunizations and getting immunized during pregnancy is especially important to prevent diseases that can cause complications. Talk to your health care provider about your immunization status and the vaccines that may be recommended for you.

Is immunization safe during pregnancy?

Immunization during pregnancy is safe and is the best way to protect the expecting mother and baby from disease that could otherwise cause harm. Some vaccines are recommended before pregnancy and others are safe to take during pregnancy. Vaccines that are recommended before pregnancy include live-attenuated vaccines, while inactive vaccines can generally be given during pregnancy.

All vaccines are safe to take while breastfeeding.

Vaccines to consider before and during pregnancy

Staying up to date on your immunizations before and during your pregnancy is important in maintaining your health and the health of your baby. Before planning a pregnancy, make sure you are up to date on all adult immunizations. Some vaccines are especially important during pregnancy, such as the influenza vaccine. Many studies have shown that women vaccinated during pregnancy have a lower risk of complications from influenza,
and so do their babies after birth.

During your pregnancy is also a great time to learn about the vaccines that your baby will need to stay healthy. Click here to learn about these vaccines. Talk to your health care provider about your immunization status and the vaccines that may be recommended for you and your baby.
