PHO Visiting Speaker Series: Validity and Feasibility of Using Biomarkers in Blood and Saliva to Monitor Measles Vaccination Coverage in Rural Bangladesh
Friday, January 20, 2012 12:00 pm to 01:00 pm
Venue: 480 University Ave. Suite 300, Toronto, ON M5G 1V2 Boardroom 345 & Webinar



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.

Presenter: Kyla Hayford

Kyla Hayford received a doctorate in international health from the Johns Hopkins Bloomberg School of Public Health (JHSPH) where she focused on the epidemiology of vaccine-preventable diseases in low-income countries.  She currently works at the International Vaccine Access Center at JHSPH on studies and policy initiatives aimed at accelerating the introduction of new and under-utilized vaccines around the world.
