A qualitative study investigating knowledge and attitudes regarding human papillomavirus (HPV) and the HPV vaccine among parents of immunosuppressed children

Abstract

Barriers influencing the willingness of parents to vaccinate immunocompetent children include a lack of knowledge about human papillomavirus (HPV) and low perception of risk regarding their child's acquisition of HPV infection. However, it cannot be assumed that the facilitators and barriers of HPV vaccination are the same for parents/guardians of children who are immunocompromised, or who have chronic medical conditions. This study aimed to document the knowledge and attitudes of parents/guardians of immunosuppressed children and adolescents towards HPV infection and the vaccine.A study using qualitative methods which incorporated 27 semi-structured interviews was undertaken with parents/guardians of immunosuppressed children vaccinated against HPV at three hospitals in two states of Australia. Thematic analysis revealed that while participants acknowledged that they had heard of HPV, they did not have a strong sense of what it actually was. The level of concern held about their child acquiring an HPV infection (prior to vaccination) ranged from ‘not at all’ to ‘extremely’. Some believed that their child was at increased risk of developing a severe HPV-related illness because of their underlying condition. The participants supported their child receiving the HPV vaccine, as they did not want to take a risk with a disease that may cause their child to return to hospital for treatment. The majority had little apprehension about the use of the HPV vaccine but expressed some concern that potential adverse effects would be more severe for immunosuppressed children. However, they stressed their belief in the safety of the vaccine and their trust in the child's health team.Our study results show that parents of children with impaired immunity would benefit from further information about the safety of the vaccine and about the important role of the vaccine for boys as well as girls.
