The child immunization card is an inexpensive yet effective instrument for systematically recording the vaccines received by a child. Moreover, the card can enhance health professionals’ ability to make clinical decisions, empower parents/caregivers in the health care of their children, and support public health monitoring. Unfortunately, the child immunization card is too often underutilized or inappropriately used by parents and health care workers and therefore does not always fulfil its intended purpose.

A repository for national immunization or child health cards has been developed to support the free and open exchange of information related to national card content and design that ultimately may be useful to the improvement of child health outcomes.
