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).
*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.
Boostrix® is licensed for use in children 10 years of age and over and adults as a booster vaccine. Boostrix® can be used, out of licensure in children from 7 years of age and adults, for one or all three doses of a primary course of tetanus and diphtheria vaccination, so as to provide protection from pertussis (whooping cough). There is no alternative vaccine that provides protection from pertussis available in New Zealand for this age group.
When children are younger than the age to which the vaccine is licensed, and when the vaccine is used for a primary vaccination course, use will be outside of current licensure and parents/guardians/individuals must be fully informed of this. There are not expected to be any safety concerns for use in these circumstances.
