Abstract

BACKGROUND:

Persistent infection with human papillomavirus (HPV) is a prerequisite for cervical cancer, which causes 175 yearly deaths and substantial morbidity in Denmark. In January 2009, HPV-vaccination for 12 year-old girls was introduced into the free-of-charge childhood vaccination programme. Due to concerns about potential poor compliance we determined the uptake and identified determinants for vaccination after the first year of the programme.

METHODS:

All vaccinations given within the vaccination programme are reported to a central register, which we linked to demographic information found in the Danish civil register. We calculated vaccination uptake and used Cox regression survival analysis to compare the uptake rates between demographic subgroups in the population, e.g. by number of siblings, age of mother (at the daughter's birth) and place of origin.

RESULTS:

The uptake among the 33,838 eligible girls was 80%, 75% and 62% respectively for the three HPV-doses. All subgroups had uptake above 68% for the first HPV-vaccination. Girls with mothers younger or older than the reference group of 25-34 years had a lower uptake rate (adjHR 0.94, 95% CI 0.91-0.97 and adjHR 0.91, 95% CI 0.88-0.94 respectively). Girls with 5 or more siblings had lower uptake rate than girls without siblings (adjHR 0.79, 95% CI 0.71-0.87). Girls born in other EU/EFTA-countries had lower uptake rate than Danish-born girls with Danish-born parents (adjHR 0.74, 95% CI 0.67-0.82).

CONCLUSIONS:

The introduction of routine HPV-vaccination in Denmark resulted in a relatively high uptake, indicating little reason for major concern about barriers towards the vaccination in Denmark. Population groups with reduced uptake were identified, but as they were small in number their effect on the overall vaccination coverage was marginal. Nonetheless, these groups should be targeted in future acceptance studies and vaccination awareness campaigns.
