UNC study: Tdap vaccine given during pregnancy reduces occurrence of infant pertussis, reinforces CDC recommendations of immunization for all mothers
University of North Carolina Health Care SystemA study led by UNC’s Sylvia Becker-Dreps, MD, MPH, reviewed more than 675,000 pregnancies in the U.S. 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.
