The Health Protection Agency (HPA) monitors and publishes quarterly COVER (Cover of Vaccine Evaluated Rapidly) uptake data, which include that from London Strategic Health Authority. These are published on the HPA website:
In order to ensure that children within primary care trusts (PCTs) using the Interim Child Health Interim Application (CHIA) received their immunisations at the right time, both regular and additional audit activities were carried out by PCTs, general practitioner practices, BT (the Local Service Provider for the London Cluster) and the Health Protection Agency. These activities have been used to validate the immunisation returns and to ensure that any children overdue an immunisation are invited to have one at the appropriate time. PCT chief executives and the Director of Public Health for London were fully engaged in and supportive of these activities.
