Key inclusion criteria
1. Child aged greater than or equal to 18 months and < 18 years with CSLD. The case definitions for CSLD are: a) CSLD: a clinical syndrome where there are symptoms indicating chronic endobronchial suppuration with or without HRCT evidence of radiological bronchiectasis. The main feature of the clinical syndrome is recurrent (3 or more episodes/yr) chronic (>4 weeks) wet cough responding to antibiotics b) BE: confirmed by chest HRCT scan in last 5 years c) 3 or more episodes of Protracted Bacterial Bronchitis. Protracted bacterial bronchitis is defined as the presence of isolated chronic (>4 weeks) of wet/moist cough that resolves with antibiotics in the absence of pointers suggestive of an alternative specific cause of cough. 2. Receipt of meningococcal C conjugate monovalent vaccine at least 6 months prior to enrolment. 3 Provision of written informed consent from parent/guardian (assent if child aged greater than or equal to10 years) 4. Parent/child willing and able to meet the requirements of the protocol 5. Not planning to move from the study area in the 12 months following enrolment.
6. At least 2 respiratory exacerbations in the preceding 18 months
Minimum age
18 Months
Maximum age
18 Years
Both males and females
Can healthy volunteers participate?
Key exclusion criteria
Prior vaccination with PHiD-CV vaccine; contraindication to PHiD-CV and/or quadrivalent meningococcal conjugate vaccine as per the Australian Immunisation Handbook and product information sheets;10 known hypersensitivity to any component of the vaccines; confirmed or suspected immunosuppressive condition or immunodeficiency disorder; current (or within 90 days prior to receiving study vaccine) or planned (during the active study period) immunosuppressive therapy, including systemic corticosteroids (greater than14 days); administration of immunoglobulins and/or blood products with 90 days prior to receiving study vaccine, or planned administration of such products during the study period.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potentially eligible children will be identified from the patient lists of the respiratory specialist departments and clinics at each of the participating study sites. The parents/guardians will be given a brief explanation of the study and provided with an information flyer and plain language statement to read at home. The attending specialist will obtain consent for the parent/guardian to be contacted by research staff to determine willingness to participate in the study. If parents/guardians are willing to discuss the study, they will be contacted by study staff for an interview over the phone to go through the study in detail. If they are interested in participating in the study, an appointment will be made for the first study visit.

Subjects will be assigned a unique subject number when written informed consent is provided. This number will identify the participant until randomisation. Once eligibility has been confirmed, a unique treatment number will be assigned at randomisation. This number will correspond to a vaccine pack which will be used to identify the participant for the duration of the study.

Group allocation and vaccine code assignments will be maintained in secure electronic and paper files that are inaccessible to all investigators, study staff and participants. The independent statistician will keep the randomisation code on file and emergency code break envelopes will be kept securely at QCMRI for use in case of an emergency.

Vaccines will be repackaged and labelled at a Therapeutic Goods Administration approved Good Manufacturing Practice facility to appear identical to study personnel and participants. The study vaccines will be packed according to the randomisation code.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A study statistician not directly involved in the analysis of study results will prepare the study randomisation code in a statistical database. A randomisation blocking scheme will be used to ensure that balance between the two treatment groups is maintained. Participants will be randomised to Group A or B (1:1 allocation), using computer generated random permuted block sizes. Randomisation will be stratified by age (< 6yrs and greater than or equal to 6 yrs), and PBB vs other CSLD (4 strata). Six years is considered the age at which spirometry can be reliably performed in children. Treatment allocation will be determined using an internet based randomisation system administered by a statistician independent to the study.

Brief summary
Chronic suppurative lung diseases in children are major causes of morbidity and mortality worldwide, particularly in disadvantaged populations. Repeated infections in childhood contribute to poor lung health in adulthood. The most common organism associated with infection is non-typeable Haemophilus influenzae (NTHi). This study aims to determine whether a vaccine against NTHi (10v-PHiD) can reduce repeated respiratory infections in children. We will be comparing the number of respiratory exacerbations in the 12 months following vaccinated between children with chronic lung disease vaccinated with 10vPHiD and children who received a meningococcal vaccine (control vaccine).
