‘It's not for the children's sake’: A qualitative inquiry into the barriers and facilitators underlying parents' decision-making for vaccinating children against influenza in Denmark

Recently, the Danish Health Authority began recommending vaccinating children aged 2–6 years against seasonal influenza, underscoring the pivotal role of children in its transmission dynamics within the wider population and the need to protect vulnerable population groups after COVID-19. Under a third followed the recommendation. For the routine Danish childhood vaccine program coverage is usually well above 90%.

Through a qualitative in-depth study with 28 key informants during the 2022/2023 influenza season, we investigated the barriers and facilitators of parents' decision-making for vaccinating their children against influenza. We found that parents' decision-making was influenced by a range of factors that present barriers or facilitators at the individual or collective levels, depending on personal antecedents and family situations. We also gained insights on how COVID-19 mass vaccination shaped parents’ attitudes and awareness toward influenza vaccination, explaining why many parents who fully complied with the COVID-19 recommendations elected to opt out of influenza.

The implications of these findings extend beyond the concrete context of parent's decision-making regarding influenza vaccination, contributing to our understanding of vaccine confidence in at least two ways. First, the limited public controversy regarding childhood influenza vaccination allows for a perspective onto low vaccine uptake that does not resort to the usual framing of a well-defined “crisis”. Second, the interaction between COVID-19 vaccination and the childhood influenza vaccination reveals how the massive pressure on parents to vaccinate themselves and their children against COVID-19 contributed to an erosion of vaccine confidence in general.
