Abstract

BACKGROUND:

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).

METHODS:

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.

RESULTS:

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.

CONCLUSION:

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.
