Why many pregnant women are advised to get Tdap

The Tdap vaccine helps protect against tetanus, diphtheria, and pertussis, also called whooping cough. During pregnancy, the main reason many clinicians recommend Tdap is to help pass protective antibodies to the baby before birth. That early protection can matter because newborns are especially vulnerable to whooping cough before they are old enough to start their own vaccine series. If you searched for why get Tdap during pregnancy, the short answer is that it is commonly recommended to help protect your baby in the first months of life.

What parents usually want to know about Tdap timing in pregnancy

When to get Tdap during pregnancy

Many pregnant women are told to get the Tdap vaccine during the third trimester. Your prenatal care team can help confirm the best timing based on how far along you are and your medical history.

Why the third trimester often comes up

You may see searches for Tdap vaccine in third trimester because this timing is commonly discussed as the window when antibody transfer to the baby is a key goal.

What if you are unsure or behind schedule

If you have not scheduled the Tdap shot while pregnant yet, it is still worth asking your OB-GYN, midwife, or clinic about your options and the next best step.
