The CDC recommends the pertussis (whooping cough) and flu vaccines during every pregnancy.
The pertussis vaccine is particularly important during pregnancy. Pertussis can be life-threatening to your newborn.
The pertussis vaccine (most commonly given in the Tdap vaccine–includes tetanus, diphtheria, and acellular pertussis) should given between 27-32 weeks gestation. The earlier the better. It will take at least two weeks for your body to make antibodies and pass them to your unborn child. Getting the vaccine around 27 weeks allows enough time for antibodies to form just in case you go into labor early.
These antibodies will normally protect the newborn until he is able to get his DTaP vaccine at 2 months (in the US).
Make sure you get this vaccine during EVERY pregnancy. The vaccine is mainly given to protect the child. You must get it every pregnancy to protect each child from pertussis. And it is safe for you to do so.
Next up…the flu shot. It is safe and recommended by the CDC to get the flu shot during pregnancy.
