INTRODUCTION

Vaccination readiness refers to psychological motives and beliefs that decisively determine individual and collective vaccination prevention behavior. Readiness to be vaccinated depends on expected individual and social benefits and harms. Differences exist in the perception of the threat of potential influenza vs. COVID-19 infection and its significance for the social environment. The study aimed to compare the 7C components of vaccination readiness for influenza and COVID-19 vaccination in adulthood.

METHODS

A total of 317 adults answered the 7C vaccination readiness scale in two vaccination-specific versions (influenza vs. COVID-19) in an online survey from September 2022 to March 2023. Data were analyzed using repeated measures, including analysis of covariance, correlations, and multiple regression.

RESULTS

For COVID-19, there is a higher readiness to be vaccinated compared to influenza regarding (  = 0.683), (  = 0.684), (  = 0.782), and (  = 0.365). However, (  = 0.161) and (  = 0.256) indicate an enhanced readiness for influenza vaccination (interaction scales × vaccination type:  = 0.602). Individual influenza vaccination recommendations and age do not or only marginally moderate these effects (interaction vaccination type × recommendation:  = 155).

DISCUSSION

The 7C subscales reveal a differentiated pattern of readiness for the two vaccination types. This emphasizes the relevance of the multidimensional structure of the construct of vaccination readiness as well as the relevance of moderating effects of the respective vaccination type on the underlying motives and beliefs. Vaccination attitudes are influenced by cultural and social conditions as well as medical standards of care. Comparing attitudes to different vaccinations in different countries thus represents an important research desideratum in order to understand the concept of vaccination readiness more comprehensively.
