Disparities in varicella vaccine coverage in the absence of public funding.

Varicella vaccine has been licensed in Canada since December 1998 but not provided free in all provinces. Through a cross-sectional telephone survey to a random sample of parents, we assessed factors associated with varicella vaccine uptake in the absence of public funding. Parents of children aged 2-3 years (Group I) and 6-7 years (Group II) were contacted between March and May 2003 in British Columbia, Canada. Response rate was 82% (Group I=571; Group II=704). Among susceptible children, varicella vaccine coverage was 21% (95% CI 18-25%) and 28% (95% CI 22-33%), respectively. There were significant disparities in vaccine coverage based on income and residence. Physician or nurse recommendation was a strong determinant of vaccine uptake as were belief in the safety and efficacy of vaccine. Among parents of susceptible children, 59% (343/582) would vaccinate their child if it were provided free; 25% (148/582) were undecided.
