A case-control study in the state of New South Wales, Australia estimated that vaccination of pregnant women with the dTpa vaccine at 28-32 weeks of pregnancy was highly effective in preventing severe pertussis in infants less than 6 months of age — with a vaccine efficacy rate of 94% against pertussis hospitalizations — and 69% effective in preventing the disease of any severity in infants less than 3 months old.
Note: The formulation used in this study is abbreviated dTpa.
