The information in this bulletin, about immunisation statistics in England, comes from:
- The Health Protection Agency (HPA) Centre for Infections (CfI) for information on childhood immunisation coverage at ages 1, 2 and 5 collected through the Cover of Vaccination Evaluated Rapidly (COVER) data collection for PCTs
- The NHS Information Centre (The NHS IC) for information about the BCG programme and reinforcing doses on the KC50 return from known providers of immunisation services.
- The Department of Health for information on persons aged 65 and over immunised against influenza for all PCTs (in conjunction with Health Protection Agency)
Subsequent to publishing this report on 30th November 2010 a number of changes were identified as being needed. These are detailed in the Errata note document above.
March 2013: Following investigation of KC50 data submitted by some Trusts from 2008-09 through to 2010-11, the HSCIC is recommending that Td/IPV and BCG data reported in tables 6, 7, 13 and 13a of this publication should be treated with some caution. See Errata note above for more information.
Please note: Issues with some newly implemented Child Health Information Systems (CHISs) over recent years have affected COVER data quality. Although some Primary Care Trusts (PCTs) reported data quality issues in 2009-10, overall fewer issues have been identified. Some caution should, however, be exercised when comparing coverage figures over time as apparent trends could reflect changes in the quality of data reported as well as real changes in vaccination coverage. While this issue will be more apparent at a local level, it will also have an impact on the national figures.
