In 2025, the second National Vaccination Insight survey on access and acceptance barriers to childhood vaccination of children under 5 years of age was conducted.

While the survey identified barriers relating to vaccine access and acceptance of both the influenza vaccine and childhood vaccines funded under the National Immunisation Program, it didn’t explore how these contribute to parental decision-making about vaccinating their child. 

To elicit further thoughts on factors that influence vaccine uptake, researchers included optional follow-up questions to the main survey questions. These invited free-text responses regarding: 

  • vaccination costs
  • ease of getting a vaccination appointment
  • parental distress about vaccination
  • parental prioritisation of vaccination. 

A separate question asked about recent exposure to worrying information about childhood vaccination. 

Researchers also asked parents follow-up questions specifically about influenza vaccination for their child. These elicited parental thoughts on getting an influenza vaccine for their child in the 2025 influenza season and if they intended to vaccinate the following year.

What did the team analyse? 

The research team analysed parents’ responses to optional free-text survey questions using a thematic approach, translating meaningful strings of text into thematically grouped codes informed by the Behavioural and Social Drivers of Vaccination framework.

For the question on exposure to worrying information about childhood vaccination, the research team analysed text responses using a World Health Organization framework that describes common themes in people’s concerns about vaccines.
