[News items on human papillomavirus and its vaccine in the Valencian press (2006-2011)].

The process of introducing the human papillomavirus (HPV) vaccine aimed at teenage girls has not been entirely without controversy in Spain. This vaccine was originally hyped as a preventive measure in the fight against cervical cancer but the resulting euphoria was tempered by a message calling for evidence. During administration of the second dose of the vaccine in February 2009, an unexpected turn of events attracted vast media coverage when two teenagers experienced adverse effects after immunization in Valencia (Spain). This study analyzes the scope and content of news items on HPV, immunization and cervical cancer published between 2006 and 2011 in two widely disseminated regional newspapers in Valencia. We also discuss the extent to which the messages transmitted may have influenced acceptability of the vaccine.
