Vaccination against the human papilloma virus (HPV) reduces the risk of a condition that often leads to cervical cancer, according to an analysis of Danish health registry data.
The study, which is published in
Acta Obstetricia et Gynecologica Scandinavica
, followed two groups of women: those born in 1993 who were offered free HPV-vaccination at the age of 15 years, and those born in 1983 who had not been offered free HPV-vaccination. Individuals were followed from age 15 to 25 years.
Vaccination coverage was 91% in the 1993 birth group and less than 0.1% in the 1983 group. A precancerous condition called high-grade cervical intraepithelial neoplasia was detected in 4% of the 15,748 screened women born in 1983 and in 3% of the 19,951 screened women born in 1993.
The investigators found a reduced risk of about 30% for high-grade cervical intraepithelial neoplasia in the 1993 birth group offered free HPV-vaccination as girls compared with the 1983 birth group not offered free vaccination.
