Children's and parents' attitudes to and knowledge about HPV vaccination following a targeted information intervention.

The aim of this study was to investigate Swedish children's and parents' attitudes and knowledge about human papillomavirus (HPV) vaccination a year after gender-neutral HPV vaccination was introduced in Sweden's national immunization program (NIP). Additional information about HPV and vaccine was provided in the extended immunazation program. In total, 276 parents and 206 children from 22 School Health Services responded to a web-based survey. Results showed that half of the children and about a third of the parents received additional Public Health Agency information about HPV vaccination, and a majority were satisfied. Parents considered HPV vaccination being important for their children's health, and both children and parents considered it important to vaccinate all genders against HPV. Both children and parents rated school nurses as most reliable source of HPV vaccination information. Teachers were also a common source of HPV and HPV vaccination information for children. Further research among teachers in Sweden is needed to explore their knowledge and abilities to inform students and parents about HPV and vaccination.
