A primary course of pertussis vaccine is given as DTaP-IPV-HepB/Hib (Infanrix-hexa) at ages 6 weeks, 3 months and 5 months, followed by a dose of DTaP-IPV (Infanrix-IPV) at age 4 years. A further booster is given at age 11 years (school year 7) as Tdap (Boostrix).
The minimum interval between doses is four weeks, and the ﬁrst dose should not be given before four weeks of age. If a course of immunisation is interrupted for any reason it may be resumed without repeating prior doses (see Appendix 2). A booster dose should be given no earlier than six months after the primary series.
See Appendix 2 for detailed catch-up immunisation information.
DTaP-IPV-HepB/Hib or DTaP-IPV may be used for primary immunisation of children aged under 10 years.
Tdap may be used for primary immunisation of children aged 7 to under 18 years.
Dose interval between Td and Tdap
No minimum interval is required between Td and Tdap,58–60 unless Tdap is being given as part of a primary immunisation course.
Tdap is recommended but not funded by the Ministry of Health for:
lead maternity carers and other health care personnel who work in neonatal units and other clinical settings (such as GPs and practice nurses), where they are exposed to infants, especially those with respiratory, cardiac, neurological or other co-morbid conditions (with a booster dose at 10-year intervals)
household contacts of newborns, including adult household and other close contacts (contacts who are aged under 18 years and who are unimmunised or incompletely immunised for their age can receive funded pertussis vaccine; see Appendix 2 for catch-up schedules)
early childhood workers (with a booster dose at 10-year intervals), although the priority is to ensure all children attending child care have received age-appropriate vaccination.
