High uptake of HPV immunisation in Scotland--perspectives on maximising uptake.

In September 2008, Scotland introduced a national human papillomavirus (HPV) immunisation programme with bivalent HPV vaccine, to prevent cervical cancer. This school-based programme routinely vaccinates girls aged between 12 and 13 years. A catch-up campaign, running over three years, also began at this time, offering vaccination to all girls aged 13 years to under 18 years old. The HPV immunisation campaign presented challenges due to this vaccine being targeted to girls in school and older girls who had left school. Following a long and comprehensive planning process, this campaign was successfully implemented across Scotland, delivering high vaccine uptake of 91.4% for three doses of vaccine in the first year (September 2008 to August 2009) for the routine cohort and 90.1% in the second year (September 2009 to August 2010) for the routine cohort. We describe the planning process, challenges and implementation strategies employed to achieve this high uptake.
