[Acceptability of human papillomavirus vaccine in mothers from Valencia (Spain)]

Abstract

Introduction: In October 2008, Valencian Community started its human papillomavirus (HPV) vaccination schedules for 14 year-old girls. The aim of this study is to assess knowledge about HPV infection and its vaccine among the mothers of these girls, and to identify factors associated with the willingness to vaccinate their daughters.

Material and methods: Cross-sectional study by means of a questionnaire to mothers of girls born in 1995, and attending secondary schools in the province of Valencia during 2010-2011. Cluster stratified random sample (n=1279).

Statistical analysis: percentages, confidence intervals, OR, Chi-squared and multivariate logistic regression contrasts.

Results: A total of 833 (65.1%) questionnaires were completed. The results obtained showed that, 76.6% of mothers had vaccinated their daughters against HPV; 93.8% knew about the vaccine, particularly through television (71.5%); and 78.5% received positive advice from a health professional which increased the vaccination of their daughters (OR: 2.4). There was low overall knowledge about HPV infection and vaccination. Confidence of the mothers in vaccines as a preventative method increases the HPV vaccination (OR: 3.8). The first reason for refusal was the fear of adverse events (45.6%).

Conclusions: Apparently, the media does not influence the willingness to vaccinate. It would be desirable to minimize the perception of risk of the vaccine. Positive health advice from a health professional can have a positive effect on vaccination. There is a gap between the level of knowledge and decision-making to vaccinate.
