Cervarix is a vaccine designed to prevent cervical cancers (squamous cell cancer and adenocarcinoma) caused by human papillomavirus (HPV) types 16 and 18. The vaccine works by preventing the formation of precancerous or dysplastic lesions through protecting against HPV-related infection and disease. This vaccine is recommended in females 9 to 45 years of age. Cervarix is supplied in pre-filled syringes capable of delivering a single 0.5ml dose.
