Abstract
The study deals with the issue of mothers' decision-making regarding their child's vaccination against pneumococcal infections. An online survey of mothers (n = 180) was based on the theory of planned behaviour (TPB).
A hierarchical logistic regression was used to test the theoretical model with the intention to vaccinate as the dependent variable. The theory proved itself as a strong predictive instrument.
The results suggest that attitude is the main predictor of the decision. The subjective norm, as the second construct of the TPB, contributes only in certain cases and the perceived behavioural control was found to have no influence at all.
The perception of vaccine-related contradictions is an important factor alongside that of attitude. These results support the idea that mothers, especially those who do not want to vaccinate their children against pneumococcal infections, primarily base their decision on their attitude.
