ABSTRACT=HPV vaccine for adolescents was recommended as an effective prevention strategy of HPV- related cancers. In Vietnam, HPV vaccination has not been introduced to male adolescent. This study was conducted to examine the acceptance of having boys vaccinated against HPV and its underlying reasoning, and to identify their parents’ willingness to pay (WTP) for HPV vaccination in central Vietnam. 785 parents of boys were interviewed based on a structured questionnaire. Parents’ acceptability of HPV vaccine for their son was identified by one question with response on 3-point scale (agree, don’t know, disagree). Multivariate logistic regression model was used to determine contributing factors to participants’ acceptance. Bidding game method was applied to elicit WTP values for HPV vaccination with initial bid of 161.2 USD. The results showed that 49.2% of parents agreed to have their son vaccinated against HPV. Factors that influenced parents’ acceptance including son’s age (OR= 1.5; 95% CI: 1.08 –1.98); being eldest son (OR= 1.6; 95% CI: 1.13 – 2.19), being mother (OR=1.4; 95% CI: 1.01 – 1.91), parents with high education level (OR= 1.7; 95% CI: 1.11 – 2.47) and their knowledge of HPV and HPV vaccine (OR= 1.8; 95% CI: 1.23 – 2.65). Average WTP value for full doses of HPV vaccine was 137.5 USD, range between 9 USD and 188.3 USD. Parents’ knowledge of HPV and HPV vaccine was only factor affecting WTP value (Rho:  0.11; p- value: 0.030). The findings suggest a strategy be introduced for HPV vaccination to male adolescent in Vietnam.
