In Scotland an immunisation programme to routinely vaccinate girls against human papillomavirus (HPV) was introduced 10 years ago. HPV is a sexually transmitted infection and some types are linked to cervical cancer. The vaccination programme is said to have nearly wiped out cases of cervical pre-cancer in young women, and led to a 90% cut in pre-cancerous cells.
More information about HPV and the research can be found on the BBC News website
