Research: Childhood vaccine coverage: provisional monthly data (England) 2026

This report presents provisional childhood vaccine coverage statistics for MMRV, rotavirus, MenB, the 6-in-1 vaccine and the dTaP/IPV booster for July 2026 in England.

Cover of vaccination evaluated rapidly (COVER) remains the official source for childhood vaccination coverage. The aim of this supplementary report is to provide more timely provisional estimates to support staff delivering the programme.

Coverage estimates in this report will differ from the official coverage figures published in COVER, as the reports use different data sources and methodology. This report is based on GP data meaning unregistered individuals are not included so figures do not capture the whole eligible population. For more details on both data sources and appropriate use cases see the Methods section.

In this report coverage is measured in those turning each age within the survey month and estimates include vaccinations administered up to the end of the survey month. This methodology means that for each age band, coverage is measured in a different cohort of children each month.

Coverage by local authority is likely to be variable, as the number of eligible individuals in each cohort is often small. This should be taken into account when interpreting these coverage estimates.

Historic data has been excluded for rotavirus in September 2023, for the 6‑in‑1 vaccine between April 2022 and April 2023 and again in October 2025, and for MenB between September 2025 and December 2025. These periods are indicated by breaks in the lines in the figures. In addition, all historic data has been excluded for MMR and the dTaP/IPV booster. Data from these periods were excluded after failing validation checks.

Sufficient data is not yet available to assess whether the introduction of the 18 month appointment has improved coverage of MMRV dose 1 and to assess coverage of MMRV dose 2 but this will be included in future publications.
