Boostrix® is used for booster vaccination of adolescents aged 11 years and pregnant women between 28-38 weeks gestation* to protect against diphtheria, tetanus and pertussis (whooping cough). Boostrix® can also be used for catch-up immunisation for children aged 7 years# to under 18 years.
*After immunisation protection against pertussis takes up to two weeks to develop. Whilst immunisation between 38-40 weeks gestation is still safe for mother and baby later immunisation means the newborn may still be exposed to the disease by their mother on delivery and/or during the first two weeks of life. The PHARMAC decision to limit funded Boostrix® to 28-38 weeks gestation maximises the benefit of immunisation against pertussis whilst being accountable for the use of public funds. Pregnant women can choose to purchase Boostrix® privately after 38 weeks gestation or at any time after delivery.
#Although Boostrix® is not licensed for use in children aged 7 years to under 10 years it has been used in New Zealand and overseas in this age group and there are no safety concerns with off-label use.
