Barriers to seasonal and pandemic influenza vaccine uptake for each risk group aggregated using the macro-level 4C model of vaccine hesitancy (complacency, convenience, confidence and calculation).

<p>Bars visualize the total number of significant results supporting each reason for hesitancy for each risk group. Grey bars indicate the absolute proportion of results addressing pandemic influenza uptake among the total results. Black bars indicate the absolute proportion of results for seasonal influenza uptake among the total results.
