Tdap

There has been persistent increases in pertussis (whooping cough) disease in the United States. As a result of this, the American College of Obstetrics and Gynecology supports the recommendations of the CDC, Center for Disease Control and the Prevention’s Advisory Committee that all pregnant women should be immunized with tetanus toxoid, reduced diphtheria toxoid and acellular pertussis (Tdap) during each pregnancy regardless of the patient’s prior history of receiving Tdap. The Department of Obstetrics and Gynecology follows the recommendation and offers the vaccine to all pregnant women at 28 weeks of pregnancy. It is further recommended that members of your household or any direct caregivers of your newborn contact their physician’s office for Tdap immunization.
