I don't know much about pregnancy vaccines, but from findings, Tdap vaccine will help protect a pregnant woman against whooping cough during pregnancy, also flu shot vaccine can be administered in cases of a flu season. Vaccinations help protect both the mother and child during and after pregnancy.
