A study reviewed more than 675,000 pregnancies in the US to determine if the Tdap vaccine given to a mother will reduce the chances of her child developing pertussis during the first 18 months of life. The results show a decrease in overall cases of pertussis, and most notably, in pertussis hospitalization in infants whose mothers were immunized during pregnancy.
