Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The school children will already be undertaking the vaccination program as part of their year 7 program at their school and consent will not be sort from them to participate in the scheduled vaccination program. De-identified, routinely collected information about returned consent forms will be provided to the investigators by Casey Council for the schools involved in the trial.

The experimental group will be provided a hand out with the consent form for vaccination that will serve the purpose of the explanatory statement and consent to receive the intervention (a pack of Vaxcards) or not in a tick box to be returned with the consent forms for their routine vaccination.

The pack of vaxcards contains 10 character cards that represent the disease vaccinated against in the immunization schedule and information about these diseases.

The intervention will be delivered once and are intended to be kept by participants and are provided with instructions on how to play the game but not provided indications of use, they may play with the cards as they wish. There are no strategies implemented to assess/monitor adherence to the intervention.

Schools participating in the vaccination program will email and mail parents and students with instructions for completing survey with explanatory statement and consent box hosted by Qualtrix

Other interventions
Comparator / control treatment
District council school vaccination program for year 7 students through consent of the participating schools. 23 Schools will be ranked in previous vaccination rate from council program and split into top 50 and bottom 50 percent, labelled high and low groups. These will be each cluster randomized to the control and experimental group for intervention.
The control group will participate in this routine vaccination program and will not be consented for the primary outcome measurement routinely collected by the council.
Control group will be explained the trial after vaccination and be offered the intervention if desired with a parental explanatory sheet after vaccination and after the primary outcome measurement has been recorded. They will be offered the option to receive the Vaxcards at the end of the vaccination program in August 2019.

Schools participating in the vaccination program will email and mail parents and students with instructions for completing survey with explanatory statement and consent box hosted by Qualtrix

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is concealed to the statistician through a central computer randomization code
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
25 schools will be block randomised to two groups (of 11 and 12). In 2018, there were 12 schools with less than 100 year 7 students and 11 schools with 100 or more. There were 8 schools with a card return less than 90%. To ensure balanced proportions of these school characteristics in the test and control groups, we will stratify the randomisation by: school number of year 7 students ('less than 100'/'100 or more') and card return (<90%/+90%).

Efficacy
Statistical methods / analysis
The study has ample power ( greater than 95%) to detect a change in proportion of 5%. Power calculation done using Stata statistical software stepped-wedge: for 23 clusters defined at the level of the school, the primary outcome measure is the return of the form (yes/no) from 120 students per school, significance level set at 0.05, intraclass correlation coefficient (ICC) within schools of 0.3, approximately half the schools receiving the intervention (ie steps equal to 1) , and data examined at two time points (baseline, year 1).

Quantitative surveys on likert scales will be analysed using chi-squared.

Summary
Brief summary
In this study we aim to test a tool that has been designed for incentivising and educating vaccination among the school age population. The primary outcome will measure return rates of consent forms of those incentivised to do so with the collection of the vaccine card game ‘Vaxcards’. Secondary outcome measures will assess the effectiveness for the tool to increase knowledge and move attitudes towards behaviour change among school age vaccine recipients and their parents.

We hypothesise that consent form return rates for community school vaccination will increase to those offered a pack of vaxcards. We also hypothesized that children and parents who receive a pack of vaxcards will show improved knowledge, attitudes and behaviors towards vaccination
