Enhancing HPV vaccine uptake in girls and boys – A qualitative analysis of Canadian school-based vaccination programs

The purpose of this study was to better understand barriers and enabling conditions for HPV vaccination in school-based vaccination programs in Canada. Semi-structured interviews were conducted by telephone or in person with parents, nurses, and school staff (n = 50) in three Canadian provinces. Interviews explored views on HPV and HPV vaccination, strengths and weaknesses of the school-based HPV vaccination programs and proposed interventions to increase uptake. Interview transcripts were coded and analyzed thematically using the socio-ecological model. Participants had positive views towards HPV vaccination and school-based offer. They identified barriers and enabling conditions at the individual and interpersonal level (e.g., knowledge, attitudes, behaviours of – and relationships between – parents, nurses, and school personnel), at the organizational level (e.g., allocated resources, information provision, process to ensure informed consent, vaccination setting and environment) and at the community and policy level (e.g., social group values and norms, media coverage around the HPV vaccine). Participants also suggested strategies to reduce identified barriers (e.g., communication interventions, simpler inform consent process). Different layers of barriers and enabling conditions of HPV vaccination in school settings were identified. Tailored interventions remain key to enhance vaccine acceptance and uptake.
