Factors affecting HPV vaccine acceptance in west Austria: Do we need to revise the current immunization scheme?

Borena, W., Luckner-Hornischer, A., Katzgraber, F., & Holm-von Laer, D., (2016). Factors affecting HPV vaccine acceptance in west Austria: Do we need to revise the current immunization scheme? Papillomavirus Research, 2, 173-177.

Background: Austria introduced a school-based gender-neutral human papillomavirus (HPV) immunization program in February 2014. In order to assure high coverage, factors influencing acceptance of the vaccine need to be identified. In this study we aim to assess parents’ attitude and related socio-demographic factors in relation to the newly implemented gender-neutral, school-based HPV Immunization program. 

Methods: Parents of 4th grade school children in 20 randomly selected primary schools were asked to fill out questionnaires on socio-demographic factors and on the level of information and attitude towards HPV infection and HPV vaccine. 

Results: A total of 439 parents with 449 vaccine eligible children participated in the study. Fifty nine percent of vaccine eligible girls and 51.8% of eligible boys received the first dose of the vaccine. Fear of side effects and child being too young for the vaccine were the most commonly cited reasons by parents electing not to let child receive the vaccine. Children who had received other school-based vaccines have more than fifteen times higher probability of receiving HPV vaccine. To have received HPV-related information from physicians positively influenced vaccine acceptance (OR (95% CI)=1.60 (1.06–2.43)). Higher paternal (fathers’) educational status significantly increased the chances of a male child to be HPV vaccinated (OR (95% CI)=2.45 (1.29–4.78)). 

Conclusion: Despite the efforts to provide HPV vaccine free-of-costs and as a school-based program, the study found that a significant proportion of vaccine eligible children failed to receive the vaccine. Involvement front line physicians and men with higher educational status may be utilised by public health policy makers in the effort to increase awareness. For a better acceptability of the vaccine, there is a need to consider lifting the age of “eligibility” for the school-based vaccination program.
