In order to estimate the current coverage rate among all children in Greenland, we conducted an observational cross-sectional study identifying all children in Greenland eligible for a vaccination between 1 March 2018 and 16 June 2019. we found an overall national coverage of 85.4%. The national coverage for the vaccinations given at birth was 97.1%, dropping to 94.3%, 87.7% and 83.6% at ages 3, 5 and 12 months. Among children eligible for the Measles, Mumps and Rubella-vaccinations, the national coverage was 76.9% for children aged 15 months and 64.1% for children aged 4 years, but dropping to 40.9% in the districts. At preschool, the national coverage was 79.9%. Among the 12-year-old, the national coverages of the two vaccinations against Human Papilloma Virus were 88.4% and 71.6%, respectively, and for the three Hepatitis B-vaccinations 89.8%, 84.1% and 69.6%. A subgroup-analysis and test of an SMS-reminder system in Nuuk improved the coverage from 57.8% to 75.5% locally. Overall, we found a high national coverage rate among the newborn in Greenland. The national coverage rates of the remaining vaccinations were below the WHO-recommendations, however with great regional differences.
