Sociocultural determinants of anticipated acceptance of pandemic influenza vaccine in Pune, India : a community survey using mixed-methods

To investigate community priority and determinants of pandemic influenza vaccine acceptance in Pune, India. Community willingness to accept vaccines is often neglected in pandemic preparedness. Despite an acknowledged need, few such studies have been done in lower income countries.; A cross-sectional, mixed-methods study used semi-structured explanatory model interviews to assess anticipated acceptance of nasal and injectable vaccines at different prices among 436 urban and rural residents. Logistic regression models identified sociocultural determinants of vaccine acceptance.; Over 93 % anticipated acceptance at no-cost; 87.8 % for INR 150 nasal vaccine; 74.1 % for INR 500 and 61.7 % for INR 1000 injectable vaccines. Some respondents preferred low-cost over free vaccines. Illness-related concerns about social isolation, contaminants identified as perceived causes, private-hospital or traditional-healer help seeking, and income were positively associated with anticipated acceptance. Humoral imbalances as perceived cause, home remedies for help-seeking and age were negatively associated.; High acceptability of pandemic influenza vaccines indicates good prospects for mass vaccination. It appeared that confidence was higher in the vaccines than in the health systems delivering them. Vaccination programmes should consider sociocultural determinants influencing vaccine acceptance.
