COVID-19 Vaccine Acceptance and Its Determinants among Migrants in Germany-Results of a Cross-Sectional Study.

Vaccinations are a core element of infection control. Migrants have been reported to have low vaccination rates for many infectious diseases, including COVID-19. Still, determinants of migrants' uptake of COVID-19 vaccinations are not sufficiently clear. The present study addresses this gap and examines the respective influence of three potential determinants: barriers to access, attitude towards vaccinations in general, and towards COVID-19 vaccines. The study uses a cross-sectional online survey among migrants in Germany. The questionnaire assessed the aforementioned determinants using standardized tools. Information on 204 individuals was available. The vaccination rate in the sample was 80%. Vaccinated as compared to unvaccinated respondents reported more often the absence of financial barriers (71% (95%CI: 64-73%) vs. 45% (95%CI: 28-63%)), short waiting times (51% (95%CI: 43-59%) vs. 22% (95%CI: 5-38%)), and the presence of a vaccination center close-by (91.5% (95%CI: 87-96%) vs. 69.7% (95%CI: 54-85%)). Concerning COVID-19 vaccine acceptance, the majority of respondents (68%) agreed that the vaccine is important. Unvaccinated respondents more often feared side effects, were convinced that the vaccine is not safe, and assumed that COVID-19 is not dangerous. Correspondingly, acceptance of vaccinations in general was higher among vaccinated respondents. In line with findings from previous studies, our survey found that all three determinants seem to influence migrants' vaccination status while their overall vaccination rate was comparable to the general population. Hence, migration background per se does not sufficiently explain vaccine acceptance and further research is needed to identify subgroups of migrants that should be specifically addressed to increase their vaccination rate.
