Acceptability and uptake of HPV vaccine in Argentina before its inclusion in the immunization program: a population-based survey.

In Argentina, human papillomavirus (HPV) vaccination was approved in 2006, but not included in the National Immunization Program. In 2008 a mass media campaign was carried out by a cancer Non-Governmental Organization (NGO), but it was stopped due to criticisms about the publicity. In October 2011 the Ministry of Health (MoH) has introduced HPV vaccination in the National Immunization Program. In this context, to assure high HPV vaccine coverage, evidence is needed on factors both associated to vaccine acceptability and uptake. In 2009-2010 we carried out a population-based survey among a representative sample of 1200 women aged 18-49 years from the Metropolitan Area of Buenos Aires. The objective was twofold: first to analyze socio-demographic determinants of women's knowledge on HPV vaccine and secondly, determinants of actual HPV vaccine uptake and acceptability in Argentina after the above-mentioned vaccine advertising shown in mass media in the year 2008. We analyzed vaccine uptake/acceptability separately for women and for their daughters aged 9-15, and willingness to vaccinate one's daughter younger than 9 to receive future HPV vaccination. Results of the 1200 women interviewed, 438 women (36.5%) knew the HPV vaccine and 303 (25%) remembered the mass media advertisement about HPV vaccination. When asked whether she would get vaccinated after having seen/heard the advertisement, around 75% (n=226) of women answered surely/probably yes. No significant differences in socio-demographic characteristics were found among women who would or not get vaccinated. When surveyed, 6 women had been vaccinated. Main reasons for non-vaccination were: "Doctor did not mention/recommend it" (34.1%) and "Vaccine is too expensive" (15.7%). No woman had had their 9-15 year-old daughter vaccinated. Among women who only had at least one daughter under 9 (n=278), 74% answered that they would get their daughter vaccinated if they were pre-adolescents. The conclusion is that, in Argentina, the potential acceptability of the vaccine is high, given that there is acceptance among the professional community, physicians recommend it, and vaccine is affordable.
