Among 6,992 participants, awareness was significantly associated with parental education (odds ratio (OR) = 0.82; 95% confidence interval (CI): 0.71–0.95), language spoken at home (OR = 0.59; 95% CI: 0.52–0.66) and deprivation level (OR = 0.57; 95% CI: 0.44–0.71), regardless of physician visit or school lessons. Vaccine uptake was associated with parental education without a recent physician visit (OR = 0.31; 95% CI: 0.16–0.59, vs OR = 0.64; 95% CI: 0.52–0.78 with a visit, interaction p = 0.045). Vaccination intention among unvaccinated was associated with deprivation level (moderate-low vs low) among students not remembering school lessons on vaccination (OR = 0.17; 95% CI: 0.05-0.62, vs OR = 0.93; 95% CI: 0.51–1.67 remembering school lessons, interaction p = 0.022). Parental education was associated with vaccination intention among students reporting a physician visit (OR = 0.41; 95% CI: 0.26–0.64 vs OR = 1.05; 95% CI: 0.50–2.20 without a visit, interaction p = 0.034).
