Understanding a national increase in COVID-19 vaccination intention: a mixed methodological approach

Abstract

Recently the Netherlands saw a substantial increase in pro-COVID-19 vaccination intention (48 to 75%). Using qualitative methods we identified vaccination beliefs and contextual factors informing this increase. Quantitative methods confirm that intentions were a function of beliefs: people with stronger intention to vaccinate were motivated most by protecting others and reopening society, those reluctant were mostly concerned by (unknown long-term) side effects. We demonstrate that belief shifts track intentional shifts, and offer insights for improving pro-vaccination campaigns.
