Cover of Vaccination Evaluated Rapidly (COVER)

The Cover of Vaccination Evaluated Rapidly (COVER) surveillance scheme evaluates the Child Immunisation Programme in England coverage for vaccines delivered before the age of 5. It replaces the Child Immunisation (GP) quarterly collection.

About this collection

This quarterly collection reports on the immunisation coverage for three cohort age groups; 12 months, 24 months and 5 years for both the local authority and GP level data. 

Please note that the GP level data is aggregate information collated and used in the normal course of business to inform operational delivery or the management of organisational performance. The information may be incomplete in places, is not quality assured to the same extent as official statistics and may not necessarily be fully representative. Data for the local authority level data is mandated and published as official statistics quarterly.

Data is collected for both local authority and GP level data quarterly from the Child Health Information System providers and submitted via the NHS Digital Strategic Data Collection Service (SDCS).


Data submission information

COVER is a quarterly data collection, with an annual reporting period also taking place alongside Q4. The exact dates for the data collections will be communicated to providers prior to them opening. Registered data submitters of the data collection will also receive emails from Strategic Data Collection Service (SDCS) confirming when the reporting window is opening and closing.
