Topic: HPV, Cervical cancer prevention

The aim of this bi-national study was to compare and contrast the knowledge, beliefs, and practices regarding human papillomavirus (HPV) vaccination among mothers of vaccine-eligible girls, health care providers, and program administrators at two community clinics in Oxnard, California, and two Mexican Social Security Institute (IMSS) clinics in Cuernavaca, Mexico. Although mothers in the US had less knowledge and more negative attitudes toward the vaccine than their counterparts in Mexico, vaccine uptake rates were higher in the US (49% vs. 40%). US mothers were more likely to have discussed and been offered the HPV vaccine by a clinician than mothers in Mexico. In multivariate analyses, having been offered the HPV vaccine was the most important predictor of vaccine uptake.
