The National Immunisation Management System (NIMS)

NIMS is the IT software provided by the System C & Graphnet Care Alliance that supports the management of the influenza and Covid-19 vaccination programmes across England.

It supports almost every aspect of the national vaccination services, from identifying prioritised patients to be vaccinated, through to recording vaccinations as they are given.  

The system was commissioned for the enhanced winter flu programme in August 2020 ahead of the Covid-19 vaccination programme.

The national Covid-19 system went live at the beginning of December 2020. It processes vaccinations given at 1,500 vaccination sites and feeds the NHS data store which is used to inform vaccination centre operations.

NIMS is the National Immunisation System of Record and provides data for Public Health England, NHS England and at ministerial level.

This system is based on System C and Graphnet’s shared record data integration technology, population health system and CarePlus specialist software for managing child health and immunisation programmes.
