Vaccination coverage estimates based on parental recall or vaccination records are widely used to monitor the performance of immunization programs in low-income countries. Biomarkers of immunity in blood and saliva are potentially more objective indicators of vaccination coverage but questions remain about the feasibility and benefits of serological surveillance. We conducted a population-based study with young children in Bangladesh to evaluate if saliva and blood testing for measles-specific IgG were objective and feasible alternatives to conventional indicators of measles vaccination coverage. Study results will be presented with a focus on the implications for surveillance and measles eradication efforts.
