Eligibility Data Product (EliD)

The Eligibility Data Product (EliD) service is designed as the single, definitive source of vaccination eligibility data. It will determine whether, according to data available to NHS England, an individual is considered to be:

a.    eligible for a particular vaccination with the associated reasons
b.    what next actions a person can take (for example, being directed to book a national appointment, or contact their GP etc.)

It standardises, enriches and summarises data from numerous sources (which are clinically assured where relevant) into one place. Business rules are then applied to determine individuals who meet the agreed criteria, and where they do, to generate suggested, personalised actions they may take.

The Eligibility Signposting API allows consuming systems to retrieve the current view of eligibility for one or more vaccine types, for a single individual, based upon the information contained within the Eligibility Data Product.

Benefits include:

• creates a single source of consistent, trustworthy and clinically assured vaccine eligibility data to satisfy multiple use cases
• avoids misalignment of rules and data sources by creating a single source - this helps reduce existing clinical safety hazards and makes it easier to align with policy and customer requirements
• provides multiple use cases with a personalised or targeted approach to increase vaccine uptake and coverage as well as target and reduce health inequalities
• cost savings by avoiding duplication of complex functionality across many systems
• ensures data minimisation avoiding the need to replicate full data sources across many services and organisations

This service is available to NHS England organisations and services that support direct care via the Eligibility Signposting API.

The service may also be used for non-direct care purposes, providing a suitable legal basis and business justification exists (this may restrict users to using non-personal data such as aggregate data). 

We use a variety of different data sources to determine whether an individual is eligible for a particular vaccination and if there are any recommended actions to get vaccinated.

We can determine if an individual is eligible for a vaccination based on:

• age

• clinical risk

We cannot currently support identifying pregnant women or individuals who are eligible due to other risks such as their occupation. We can recommend actions for the individual to take, such as signposting them to appropriate services, based on:

• where they they live (address registered with their GP)
• their GP registration

Business rules can also be used to determine appropriate actions for the following scenarios:

• if they are already vaccinated
• if there is no current campaign
• if there is insufficient time since their previous vaccination
• if their next dose is not yet due (for multi-dose vaccinations)

This service is in development. 

The Eligibility Data Product is a silver service, meaning it is available 24 hours a day, 365 days a year (excluding planned downtime). It is supported from 8am to 6pm, Monday to Friday, excluding bank holidays. 

To access this service via the Eligibility Signposting API, you will need to complete the Digital Onboarding process.
