Centre for Infections (CfI) for information on childhood immunisation uptake at ages 1, 2 and 5 collected through the Cover of Vaccination Evaluated Rapidly (COVER).Long-term trends for MMR immunisations in London and England are available, back to 1988/89. It is not possible to easily display the long term trends for all regions since the definitions and boundaries of the other English regions has changed a number of times during this period - though data for London has always remained available.
