Abstract

Objective: To describe maternal intention and maternal-reported HPV vaccination uptake and explore associated factors among selected girls.

Methods: A cross-sectional analytical study included 360 mother–daughter dyads from three lower secondary schools in Thai Nguyen Province; 347 dyads had complete data for intention and reported uptake. Modified Poisson regression with robust variance estimated prevalence ratios (PRs) and 95% confidence intervals.

Results: Among 347 dyads, 286 mothers (82.4%) intended future vaccination and 45 girls (13.0%) were reported to have received at least one dose. Of 302 girls with no reported prior dose, 247 (81.8%) had mothers intending future vaccination. Reported uptake was associated with trust in the vaccination facility (aPR=2.91; 95% CI: 1.55–5.48) and willingness to pay the stated price (aPR=5.46; 95% CI: 2.76–10.79).

Conclusion: Reported initiation was low, while intention among mothers of girls with no reported dose was high. The cross-sectional associations with trust and willingness to pay are exploratory and non-causal. Accessibility, safety communication and school–health coordination should be evaluated prospectively.
