由于人乳头瘤病毒（HPV）疫苗的高成本和不存在支持青少年疫苗接种的结构，尼日利亚的HPV疫苗接种将需要大量资金。需要其他来源来维持政府资助的HPV疫苗接种计划。这项研究评估了尼日利亚母亲对HPV疫苗的支付意愿（WTP）。我们还比较了平均支付意愿与青春期前女孩（CVG）接种疫苗的估计成本之间的差异。我们进行了一项定量的，横断面的，基于调查的研究，其中50份问卷分发给位于阿南布拉州两个农村和一个城市的10所中学。然后将调查问卷随机分发给9-12岁的女孩交给她们的母亲。使用支付卡技术的条件估值方法被用来估计调查参与者的平均最大支付意愿。使用多变量logistic回归获得HPV疫苗接种的WTP相关性。通过调整坦桑尼亚HPV疫苗接种成本以适应尼日利亚环境，获得了估计的CVG。共回收问卷438份（88%）.平均支付意愿为11.68美元。这与按疫苗联盟提供的疫苗价格计算的城市和农村人口的估计交付成本分别为18.16美元和19.26美元，按可获得的最低公共部门疫苗价格计算的城市和农村人口的估计交付成本分别为35.16美元和36.26美元不同。对HPV疫苗的需求被认为很高（91.6%），并且与先前诊断为HPV感染的受访者显著相关。HPV疫苗的需求很高，但低于估计的CVG。应充分利用对疫苗的高需求，增加疫苗接种。应促进关于宫颈癌的教育和提供者发起的疫苗接种，以增加疫苗接种。在全国HPV疫苗接种的情况下，共同支付可能是一种可行的筹资策略。
Human papilloma virus (HPV) vaccination in Nigeria will require substantial financing due to high cost of HPV vaccine and inexistence of structures to support adolescent vaccination. Alternative sources are needed to sustain the government funded HPV vaccination programme. This study assessed Nigerian mothers’ willingness-to-pay (WTP) for HPV vaccine. We also compared the difference between the average WTP and estimated costs of vaccinating a pre-adolescent girl (CVG). We conducted a quantitative, cross-sectional, survey-based study in which 50 questionnaires were distributed to each of 10 secondary schools located in two rural and one urban city in Anambra state. The questionnaires were then randomly distributed to girls aged 9–12 years of age to give to their mothers. Contingent valuation approach using the payment card technique was used to estimate the average maximum WTP among the survey participants. Correlates of WTP for HPV vaccination were obtained using multivariate logistic regression. Estimated CVG was obtained by adapting cost of HPV vaccine delivery in Tanzania to the Nigerian setting. A total of 438 questionnaires (88 %) were returned. The average WTP was US$ 11.68. This is opposed to estimated delivery cost of US$ 18.16 and US$ 19.26 for urban and rural populations respectively at vaccine price offered by the Vaccine Alliance (Gavi) and US$ 35.16 and US$ 36.26 for urban and rural populations respectively at the lowest obtainable public sector vaccine price. Demand for HPV vaccine was deemed high (91.6 %) and was significantly associated with respondents previously diagnosed of HPV infection. Demand for HPV vaccine was high although short of estimated CVG. High demand for vaccine should be capitalized upon to increase vaccine uptake. Education on cervical cancer and provider-initiated vaccination should be promoted to increase vaccine uptake. Co-payment could be a feasible financing strategy in the event of national HPV vaccination.
