The Advisory Committee on Immunization Practices (ACIP) has recently changed its recommendation for Tdap and pregnancy. The ACIP recommendations now include administering Tdap after 20 weeks gestation instead of postpartum, since pregnancy registries have determined that there is no adverse effect and that fewer newborns contract pertussis if their mothers are vaccinated antepartum.

The complete list of recommended guidelines is available at www.cdc.gov/mmwr/preview/mmwrhtml/mm6041a4.htm?s_cid=mm604 1a4_w.
