Brief summary
This study will be investigating the use of a new whooping cough vaccine in adults aged 18 - 30 years. Pertussis infection rates within this age group have been rising since the early 2000s and this is likely due to the short-term protection offered by the current pertussis booster vaccine. The study will compare the use of this new vaccine to the vaccine currently used in Australia. Randomisation will be based on the pertussis vaccination history of each particular subject and all subjects will be followed up for one year. They will have blood sampled before vaccination, at 28 days following vaccination and 1 year after vaccination. The expected outcome is that the new pertussis vaccine will demonstrate superior immune response and therefore extended protection against pertussis.
Interventions
Pertagen® (Pertussis Toxoid 5 µg, Filamentous hemagglutinin 5 µg, Aluminum Hydroxide 0.3 mg/dose (as Al3+), Sodium Chloride 4.38 mg, water for injections quantity sufficient to make up to a volume of 0.5 mL). To be administered as a single 0.5mL dose injected intramuscularly, preferably into the non-dominant deltoid. The vaccine will be administered by appropriately trained study staff (nurses) delegated as unblinded vaccinators.
