Vaccine Safety for Moms-To-Be

vaccine safety for moms to beVaccines help protect pregnant women and babies against serious diseases


Pregnant women share everything with their babies. That means when a pregnant women gets vaccines, she isn't just protecting herself  she is giving the baby some early protection too.


CDC has recommendations for the vaccines needed before, during, and after pregnancy. Currently, CDC routinely recommends Tdap and flu shots during pregnancy.

  • Get the Tdap vaccine (to help protect against whooping cough), during pregnancy.
  • The flu shot can be given before or during pregnancy, depending on whether or not it's flu season during a pregnancy.
  • It is safe for pregnant women to receive vaccines right after giving birth, even while breastfeeding.
  • Some vaccines, such as the measles, mumps, rubella (MMR) vaccine, should be given a month or more before pregnancy if a pregnant woman didn't get the vaccine as a child.


Live virus vaccines, such as the MMR and chickenpox shots, should not be given to pregnant women, but should be given to women before or after pregnancy, if indicated. Talk to your doctor about the MMR, Tdap, and flu vaccines before getting vaccinated.



Vaccine safety before, during, and after pregnancy

It's important to know that the Tdap and flu vaccines are safe for a pregnant woman and her baby.


It is important for women to get MMR before they become pregnant to reduce the risk of Congenital Rubella Syndrome (CRS), which can cause severe birth defects and neurodevelopmental problems. Even though MMR is a safe and effective vaccine, there is a theoretical risk to the baby. This is because it is a live vaccine, meaning it contains a weakened version of the living viruses.

  • Live vaccines are generally not recommended during pregnancy.
  • If a pregnant woman did not get MMR as a child, she should get the vaccine before pregnancy.


All vaccines are help to the highest standards of safety - meaning they are carefully studied and monitored for side effects. Vaccines are like any medicine, which means they can have some side effects. However, most people who get vaccinated have no side effects or only mild side effects. CDC continually monitors vaccine safety, and the most common side effects seen are mild and go away quickly on their own (redness, swelling, and tenderness at the site where the shot was given).


For more studies, the FDA also has a pregnancy exposure registry, which is a study that collects health information from women who take medicines or vaccines when they are pregnant.
