Timeline of Adolescent and Adult Recommendations

On June 30, 2005, the Advisory Committee on Immunization Practices (ACIP) voted to recommend the routine use of Tdap vaccines in adolescents aged 11–18 years in place of tetanus and diphtheria toxoids (Td) vaccines.

On October 26, 2005, the ACIP voted to recommend routine use of a single dose of Tdap for adults 19-64 years of age to replace the next booster dose of tetanus and diphtheria toxoids vaccine (Td). The ACIP also recommended Tdap for adults who have close contact with infants younger than 12 months of age.

On October 27, 2010, the ACIP voted to recommend:

  1. use of Tdap regardless of interval since the last tetanus or diphtheria containing vaccine,
  2. use of Tdap in certain adults ages 65 and older, and
  3. use of Tdap in under-vaccinated children ages 7 through 10 years.

On June 22, 2011, the ACIP voted to recommend:

  1. that women's health-care personnel implement a Tdap vaccination program for pregnant women who previously have not received Tdap. Health-care personnel should administer Tdap during pregnancy, preferably during the third or late second trimester (after 20 weeks gestation). If not administered during pregnancy, Tdap should be administered immediately postpartum.
  2. that adolescents and adults (e.g., parents, siblings, grandparents, child-care providers, and health-care personnel) who have or anticipate having close contact with an infant aged <12 months should receive a single dose of Tdap to protect against pertussis if they have not previously received Tdap. Ideally, these adolescents and adults should receive Tdap at least 2 weeks before beginning close contact with the infant.

On February 22, 2012, the ACIP voted to recommend use of Tdap in all adults aged 65 years and older.

On October 24, 2012, the ACIP voted to recommend that health-care personnel should administer a dose of Tdap during each pregnancy irrespective of the patient's prior history of receiving Tdap. Optimal timing for Tdap administration is at 27 through 36 weeks gestation.
