Acceptability to Latino parents of sexually transmitted infection vaccination

Objective.-To evaluate the acceptability to Latino parents of having their adolescent children vaccinated against sexually transmitted infections, and to identify potential demographic correlates of acceptability. Methods.-We applied established methodology to a sample of 119 Latino parents who accompanied their children (51% female, aged 12-17 years) to medical appointments. The parents used computer-based questionnaires to rate 9 hypothetical vaccine scenarios. The scenarios had 4 dimensions: mode of transmission (sexually transmitted or not sexually transmitted), severity of infection (curable, chronic, or fatal), vaccine efficacy (50%, 70%, or 90%), and availability of behavioral methods for prevention (available or not available). Willingness by parents to vaccinate their adolescents under each vaccine scenario was assessed on a scale (range, 0-100). Conjoint analysis was used to determine the relative contribution of each dimension to the ratings. Results.-The study sample consisted of predominantly Mexican immigrant parents, 94% of whom chose to complete the Spanish version of the computerized interview. The mean value of the parents willingness to accept vaccination for their adolescent children was exceptionally high. For example, the mean score of the Latino parents for the 6 sexually transmitted infection (STI) vaccine scenarios (score 86.2; SD 21.1) was far higher than the meanscore in previous studies (81.3, SD 21.1). Conjoint analysis revealed that the dimensions of vaccine efficacy and severity of infection were equal in terms of their influence on vaccine ratings for the Latino parents. The next most influential dimension on vaccine ratings was the availability of behavioral prevention, followed by the sexual transmissibility of the infection. Conclusions.-Our sample of predominantly Mexican parents was accepting of the concept of STI vaccination for their adolescent children. Important issues for parents include vaccine efficacy and severity of infection, followed by vaccines for infections that had no method of behavioral prevention available. Overall, there is little difference in the relative preference of a STI versus non-STI vaccine for their adolescent children.
