Annexe B – Polio campaign target vaccine uptake, data recording, monitoring vaccine coverage and evaluating impact

Published 10 August 2022

Applies to England

Campaign aims

The aim is to achieve 100% offer of an inactivated polio vaccine (IPV) containing vaccine to all children in the target age cohort in London as rapidly as possible. In order for the campaign to be successful targeted interventions to enable high uptake in traditionally under-vaccinated communities are likely to be needed. This will ensure we prevent cases of paralysis and increase the likelihood that transmission of the poliovirus is interrupted.

If successful this should prevent further escalation of the situation and limit the need to deploy additional interventions in the medium to long term.

Call and recall

The Child Health Immunisation Services (CHIS) will support regional call and recall services. CHIS will also update point of care recording so that additional doses for those with a complete course can be accurately recorded.

Data recording and transfer

Accurate recording of all vaccines given, and good management of all associated documentation, is essential as per the standards set out in the core service specifications, Statement of Financial Entitlement (SFE) and contracts.

The Provider must ensure that information on vaccines administered, including the product name of the vaccine administered is submitted directly to the Registered General Practitioner and any relevant population vaccination registers, in most areas this is the CHIS.

Following a vaccination session/clinic or individual vaccination, local arrangements should be made for the transfer of data onto the relevant CHIS. Where possible this should aim to be within 2 working days.

Arrangements will also be required to inform neighbouring areas when children resident in their area are immunised outside their local area.

Monitoring vaccine coverage

An initial view of capacity and geographical coverage will be requested of systems, with support and targeted outreach offered to areas of low coverage. Following the programme launch, coverage will be monitored through uptake measures across key variables such as age, and regional identifiers.

Reporting on this will be produced in-week, to identify areas and ages of low uptake and support corrective action.

Evaluating impact

The impact of the IPV campaign will be evaluated through monitoring of vaccine coverage (including inequalities), continued environmental surveillance, and enhanced surveillance of paralytic polio presentations.

Other studies, such as stool surveys, are also being explored to determine whether further interventions are required. The UK Health Security Agency (UKHSA) will continue to closely monitor emerging evidence around the polio incident and the control measures deployed. The Joint Committee on Vaccination and Immunisation (JCVI) will issue further advice on additional interventions if required.
