A retrospective cohort study was conducted on infants of mothers delivering at an inner-city hospital in October 2009 where postpartum maternal tetanus toxoid, reduced diptheria toxoid and acellular pertussis (Tdap) vaccination had been initiated in May 2008. We compared mothers and infants in a Tdap intervention group discharged July 2008 (n = 250) with a pre-Tdap control group discharged July 2007 (n = 238). Postpartum maternal Tdap impacted positively timeliness of early infant immunization.
