Acculturation, trust to health care system, and attitudes to COVID-19 vaccination: A comparative study between Polish immigrants in Norway, Polish in Poland, and Norwegians in Norway

Fast deployment of safe and efficient COVID-19 vaccines has changed the course of the pandemic in many countries reducing COVID-19 death rates and allowing countries to abandon strict measures such as social distancing and restrictions to public events. The vaccination strategy, however, is based on the expected high vaccination rate in the population. Several studies have indicated vaccination hesitancy to be higher in ethnic minority communities, which can lead to unnecessary suffering and loss of lives, worsening pre-existing health inequalities and marginalization of ethnic minority groups. The aim of the present study was to investigate the relationships between acculturation to Norwegian culture, trust in health authorities, and attitude to COVID-19 vaccine among Polish immigrants in Norway. An internet-based survey including questions about attitude to COVID-19 vaccination and trust in the health care system was filled by 150 Polish immigrants in Norway, 256 Polish living in Poland, and 264 Norwegians living in Norway. In addition, the Polish immigrants also answered questions about acculturation to Norway. The results showed that the Polish immigrants in Norway had less positive attitudes to COVID-19 vaccination than the Norwegians, while they did not differ from Polish living in Poland. The Polish immigrants also indicated lower trust in the Norwegian health care system than the Norwegians. In regression analysis, the trust in the values of the health care system was the most important predictor of COVID-19 vaccination attitudes in all three samples. A path model showed that trust in the values of the health care system mediated the effects of acculturation to Norway on COVID-19 vaccination attitudes among Polish immigrants. These results underline the importance of taking ethnic minorities and immigrants into account in the health care system to reduce COVID-19 vaccination hesitancy.
