Brief summary
The aim of this study is to test the impact of different messages about COVID-19 vaccines in parents of children aged 5-11 years on intention to take their child for a COVID-19 vaccine. The hypothesis is if persuasive messaging affects intention to vaccinate, then mean intention to vaccinate will be higher in persuasive messaging conditions than the control. Participants will receive 1 of 4 information conditions or a control. The 4 information conditions will focus on: the personal health impacts of vaccinating; family and community health impacts of vaccinating; non-health benefits of vaccinating; and personal choice and control associated with vaccinating. The control will be text about eligibility for paediatric COVID-19 vaccines. Analysis will compare the primary outcome measure (intention to vaccinate child aged 5-11 years for COVID-19) between intervention groups and the control (4 comparisons) using an ANOVA test. Secondary analyses will compare secondary outcome measures (beliefs about COVID-19 vaccines) between intervention groups and the control using an ANOVA test.

The intervention is a short piece of written material designed to encourage parents to vaccinate their child aged 5-11 years for COVID-19. The messages were designed specifically for this study. The intervention is delivered as part of an online experiment over the internet. After answering some questions about themselves, participants are asked to read the written information on their computer or phone screen. They are given the intervention once. The anticipated time needed to read the text is approximately 30 seconds. Participants must spend a minimum of 30 seconds on this screen. This requirements to stay on the intervention screen is used for the purpose of encouraging adherence to the intervention. There is no further assessment of intervention adherence. Arm 1 is a message focusing on the personal health impacts of vaccinating. Arm 2 is a message focusing on family and community health impacts of vaccinating. Arm 3 is a message focusing on non-health benefits of vaccinating (freedom messaging). Arm 4 is a message focusing on personal choice and control (personal choice-based messaging).
