Outcomes
Primary outcome [1] 304579 0
Incidence rate of medically attended acute respiratory infections in infants. Endpoint case definition of ALRI is a medically attended episode of illness defined as the presence of acute cough, dyspnoea, raised respiratory rate for age, new abnormal chest exam findings or radiographic findings for presumed respiratory illness. Clinic visits for ALRIs within 2 weeks of each other will be counted as part of the same ALRI. Outcome assessed by parent report and medical record review.

Infant systemic immune responses (TNF-alpha, IFN-y, IL-6, IL-13, IL-1beta) from peripherical blood mononuclear cells (PBMC). Briefly, PBMC (1x106 cells/ml) will be challenged with live NTHi or Spn (4x106 colony forming units/ml), phyto-hemagglutinin (PHA; positive control) or medium alone (baseline control). Cytokine protein, representative of innate response (TNF-a), Th1- (IFN-gamma) and Th2-immune response (IL-6, IL-13) and inflammation regulation (IL-1ß,) will be measured in culture supernatants at 24 or 72 hours.

Statistical methods / analysis
For primary aim: The main effects of the intervention will be determined by comparing the primary outcome (rate of ALRI); in the first year of life between groups (PHiD-CV group vs controls). We will report incidence rate ratio ((with 95%CI) using negative binomial regression model.

Sensitivity analyses will be performed by ALRI classification (ie ALRI case-definition confirmed, medically attended respiratory illness case-definition not confirmed, parent reported respiratory illness, and ALRIs episodes with/without antibiotics prescribed). We plan a preliminary analysis when 50% of the sample size for primary outcomes are available at 6-mo. We plan a 6-month analysis (rather than at 12-months, our RCT’s outcome) for safety reasons,

For secondary lab outcomes: We will compare differences between groups in: (i) IgGs geometric means of PD23 and serotype-specific Spn16 using Student’s T test after log transforming data (+/- maternal prevaccine levels adjustment); (ii) cytokine levels of PBMC-stimulated cells (Mann-Whitney23,47); (iii) NP Hi and Spn (vaccine and non-vaccine types separated) using Chi2 expressed as OR (95%CI).

For ALRI outcomes: A Kaplan-Meier curve will be constructed for each group for time to the 1st ALRI and respiratory-related hospitalisation, log-rank test performed and hazard ratio reported (using Cox regression model).

We will also analyse results based on the different definitions of ALRIs (pneumonia confirmed by chest x-ray and clinically defined] and hospitalised ALRI episodes, with and without antibiotics).

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
There are specific cultural issues around the sharing of data from Australian Aboriginal and Torres Strait Islander peoples. It is standard Menzies policy that IPD cannot be shared without individual approval from participants and we have not sought consent from the participants for this.
