Immunizations and Pregnancy - Topic Overview
If you are already pregnant and are not immune
If you are not immune to rubella, measles, or chickenpox, your doctor will recommend that you not have the vaccine until after childbirth. Instead, you must take every precaution to prevent exposure to these viruses while you're pregnant.
If you are at risk of being exposed to hepatitis B, hepatitis A, rabies, polio, meningitis, or pneumococcal bacteria, your doctor may recommend that you get vaccinated against these infections during pregnancy.
If you are age 26 or younger and you did not already get the human papillomavirus (HPV) vaccine before you became pregnant, your doctor may suggest this vaccine after pregnancy.
Smallpox has been eliminated from all places in the world except for research labs. Smallpox vaccine is not recommended during pregnancy because of the small chance that it can affect you or the fetus. But risks related to the vaccine are not as great as the risk of having smallpox infection. So, in the unlikely event that you have or may have been exposed to smallpox, you would be vaccinated to reduce the severity of this life-threatening illness.
Routine vaccination is safe for you and your baby during breast-feeding.
