The National Immunisation Management System (NIMS)

The National Immunisation Management System, provided by the System C & Graphnet Care Alliance, supports almost every aspect of a vaccination service, from identifying and inviting individuals to be vaccinated, through to recording vaccinations as they are given. It can also be used as a powerful analytical tool to interrogate and report vaccination data at local, regional, and national level in real-time.

The system has been used to support the English national Covid-19 and influenza vaccination programmes since 2020, and, in September 2022, it was rolled out to cover the Measles, Mumps and Rubella (MMR) vaccine. Since its launch, NIMS has securely managed and processed the data of the entire General Practitioner (GP) registered English population (approximately 60m individuals), and supported the sending of over 120m letters, 57m emails, and 160m Short Message Service (SMS) texts. The system has also recorded more than 180m vaccination events and handled over a billion API requests from third party systems.
