The document provides an overview of an Electronic Vaccine Data System (EVDS) that has been developed to collect and provide patient, health establishment, vaccine, and safety information for monitoring vaccine uptake, coverage, and effectiveness studies. The EVDS will leverage existing systems and must support the collection of demographic information, doses received, health establishment, vaccine details, and adverse event reporting. It will allow for preregistration of health care workers and other recipients, with data prepopulated from existing databases. Vaccinators must be able to see dose details. The system will also link to laboratories to monitor effectiveness and include adverse event monitoring and reminder functions. Training objectives are listed to instruct vaccinators and administrators on using the system.
