RESUMEN
AIMS: Studies have suggested that some minority groups tend to have lower vaccination rates than the overall population. This study aims to examine COVID-19 vaccination rates among healthcare workers in Norway, according to immigrant background. METHODS: We used individual-level, nation-wide registry data from Norway to identify all healthcare workers employed full time at 1 December 2020. We examined the relationship between country of birth and COVID-19 vaccination from December 2020 to August 2021, both crude and adjusted for, for example, age, sex, municipality of residence and detailed occupation codes in logistic regression models. RESULTS: Among all healthcare workers in Norway, immigrants had a 9 percentage point lower vaccination rate (85%) than healthcare workers without an immigrant background (94%) at 31 August 2021. The overall vaccination rate varied by country of birth, with immigrants born in Russia (71%), Serbia (72%), Lithuania (72%), Romania (75%), Poland (76%), Eritrea (77%) and Somalia (78%) having the lowest crude vaccination rates. When we adjusted for demographics and detailed occupational codes, immigrant groups that more often worked as healthcare assistants, such as immigrants from Eritrea and Somalia, increased their vaccination rates. CONCLUSIONS: Substantial differences in vaccination rates among immigrant groups employed in the healthcare sector in Norway indicate that measures to improve vaccine uptake should focus on specific immigrant groups rather than all immigrants together. Lower vaccination rates in some immigrant groups appear to be largely driven by the occupational composition, suggesting that some of the differences in vaccine rates can be attributed to variation in vaccine access.
RESUMEN
BACKGROUND: Vaccination coverage for COVID-19 varies among immigrant groups in Norway and between different countries. Most likely, childhood/adolescence and consistent contact with the country of birth help form the attitudes to and the desire for vaccination. We therefore compared the vaccination rate among European-born immigrants in Norway and the vaccination coverage in their countries of birth. MATERIAL AND METHOD: Vaccination coverage, the percentage of the adult population that had received at least one vaccination dose, for 22 European countries with universal access to vaccines by 31 August 2021 was retrieved from the European Centre for Disease Prevention and from the Norwegian emergency preparedness register for COVID-19 for the equivalent immigrant groups in Norway on 30 September 2021. Scatter plots with least-squares regression lines showed the association between the vaccination coverage in the country of birth and the rate in the equivalent immigration group in Norway, in total and by time of residence in Norway (< 6 years and ≥ 6 years). RESULT: The model estimated an increase in the vaccination rate in immigrant groups in Norway of 0.64 percentage points for each percentage point increase in the vaccination coverage in their European countries of birth, and explained 63 % of the variation in the vaccination rate in the immigrant groups. There was no statistically significant difference in the co-variation with the country of birth when comparing immigrants with short versus long time of residence. INTERPRETATION: There is a correlation between the vaccination rate for COVID-19 among European-born immigrants in Norway and the coverage in their countries of birth. Attitudes to and desire for vaccination varies between countries and can explain part of the observed differences between immigrant groups in Norway.

BACKGROUND: High vaccination coverage against COVID-19 limits COVID-19-related infections, hospitalisations and deaths. Studies have shown varying vaccine willingness and vaccine coverage in different minority groups. This study investigates the vaccination coverage among persons with various immigration and country backgrounds in Norway. MATERIAL AND METHOD: The study includes all persons over 18 years of age resident in Norway with a Norwegian national identity number. We used data from Beredt C19, the Norwegian emergency preparedness register for COVID-19, and investigated the association between vaccine status and immigrant and country background using logistic regression models, adjusted for income, education, sex, age, medical risk group and place of residence. RESULTS: Foreign- and Norwegian-born persons with foreign-born parents had a lower COVID-19 vaccine coverage than those who were Norwegian-born with Norwegian-born parents. Vaccination coverage for different country backgrounds varied from around 45 % for persons from Latvia, Bulgaria, Poland, Romania and Lithuania to 92 % for persons from Vietnam, Thailand and Sri Lanka. Those in the former group had from 15 to 18 times (unadjusted) and from 8 to 11 times (adjusted) higher odds of not having been vaccinated as persons with a country background from Norway. INTERPRETATION: There is considerable variation in COVID-19 vaccine coverage between different immigrant groups in Norway. The differences can be explained to some extent by income and education, but this does not explain the bulk of the observed differences. We cannot rule out the possibility that some differences are attributable to weaknesses in the registers.
