By providing a place in which children can be accessed, the school has long been a site for population-level health initiatives. Recent policy shifts towards health-promoting schools have however re-cast the school from passive host to active collaborator in public health. This paper examines secondary school teachers' views of their roles as partners in Scotland's human papilloma virus vaccination programme. Focus groups were held in seven schools across Scotland. Confusion was evident in relation to this role, with competing understandings of young women's sexuality, concerns about parental perceptions and uncertainty about professional responsibilities. Many teachers sought to distance themselves from the vaccination programme. Evidence was found of a "sedimentation of discourses", as mass models of state-sanctioned health intervention persist alongside contemporary discourses of individual choice. (Contains 1 table.)
