A qualitative study on COVID-19 pandemic impacts on parental attitudes and intentions for routine adolescent vaccinations: The role of trust.

Introduction: The COVID-19 pandemic has contributed to declines in routine childhood and adolescent vaccination coverage globally. While the declines in Australia have been less, they are a concern, given steady increases in coverage prior to the pandemic. Given limited evidence on how the experiences of parents during the pandemic affected their attitudes about and intentions towards adolescent vaccinations, with this study we aimed to explore these.

Methods: This was a qualitative study. We invited parents of adolescents eligible for school-based vaccinations in 2021 from metropolitan, regional and rural areas of New South Wales and Victoria (the most affected States) and South Australia (less affected) to half hour-long online semi-structured interviews. We analysed data thematically and applied a conceptual model of trust in vaccination.

Results: In July 2022 we interviewed 15 accepting, 4 hesitant and two parents who refused adolescent vaccinations. We identified three themes: 1. Pandemic impacting on professional and personal lives and routine immunisations; 2. Pandemic strengthening preexisting vaccine hesitancy, with perceived lack of clarity in governmental information about vaccination and stigma around non-vaccinating as contributing factors; 3. Pandemic raising awareness of the benefits of COVID-19 and routine vaccinations, with communication campaigns and one's trusted doctor's vaccination recommendations as contributing factors.

Conclusions: For some parents, experiences of poor system readiness and growing distrust towards health and vaccination systems strengthened their pre-existing vaccine hesitancy. We offer recommendations on how trust in the health system and immunisation can be optimised post-pandemic to increase uptake of routine vaccines. These include improving access to vaccination services and clear, timely information about vaccines; supporting immunisation providers in their immunisation consultations; working alongside communities, and building capacity of vaccine champions.
