<p>It's great that you're considering the Tdap shot to protect yourself and your baby from pertussis (whooping cough). The Centers for Disease Control and Prevention (CDC) recommends that pregnant women receive the Tdap vaccine during each pregnancy, preferably between 27 and 36 weeks. This helps pass on protective antibodies to your baby, who will be vulnerable to pertussis until they can receive their own vaccines. It's understandable to feel nervous, but the benefits of the vaccine outweigh the risks. Talk to your OB about any concerns you have, and they can provide more information and address your specific situation.</p>
