GSK Biologicals' dTpa vaccine has recently been approved by the US Food and Drug Administration (FDA) for booster vaccination of adolescents aged 10 to 18 years. The ACIP has recently issued provisional recommendations for universal adult Tdap vaccination. The current study will provide pivotal data in support of extending the age range for Boostrix vaccine to include adults 19-64 years of age.
