Millions of children die every year across the world as a result of not being immunized. Nigeria has
made great improvements in childhood immunizations, but it still lacks the effectiveness and efficiency
that an immunization tool may be able to provide. The Bill and Melinda Gates Foundation proposed a
Records for Life project asking teams to develop innovative immunization records for countries across the
world. The authors of this article responded to that project announcement, and although the team did not
get selected, the International Federation of Health Information Management Associations (IFHIMA)
expressed interest in the proposed record. This article describes the need for and the design of a new
immunization record for Nigerian families to use so that immunizations can continue to increase across
all geopolitical zones in Nigeria. The immunization tool is called the RAINBOW (Rapid Access
Immunization Now: Better Our World) Record and includes a colorful, useable, inexpensive, primarily
paper-based record that rewards children with stickers and fun approaches when immunizations are
completed. It also incorporates health information technology practices that can be used if the
immunization record (built in Excel) is linked to an electronic health record.
