AU-3S, with technical support from the MHRA, has created an AEFI form in the Med Safety App to report AEFIs associated with any vaccine. The form is based on the WHO core variables for vaccine reporting and was first made available to all AU-3S pilot countries. The form has since been rolled out to all other Med Safety App users from countries using the App across the globe.

All reports entered into the Med Safety App are stored in the Vigilance Hub, the backend of the Med Safety App. Reports on the Vigilance Hub are synced with national databases and thus uploaded to VigiBase through normal processes.
