The Better Immunization Data Story


Ona’s involvement in PATH’s BID Initiative began in January 2017, when we started developing the Zambia Electronic Immunization Register (ZEIR), in partnership with PATH, Zambia MOH, and BlueCode. ZEIR, built on top of OpenSRP, targets nurses and other frontline health workers in Zambia to help them track immunizations and identify missed children.

Read about the entire experience in PATH’s The BID Story, which includes perspectives from Matt Berg, Ona’s CEO, and other key stakeholders in the initiative. See how ZEIR led to a 27% increase in health workers’ ability to identify vaccine defaulters.
