Whooping cough: Boosterix (dTpa): Before planning pregnancy, or for both parents as soon as possible after delivery of an infant, (preferably prior to hospital discharge), unless contraindicated. This recommendation is based on evidence from a study of infants hospitalised with pertussis around Australia in 2001, which indicated that parents were the presumptive source of infection in over 50% of cases.
