## Methodology

OHID Fingertips upper-tier local-authority indicators for MMR one dose at age two and two doses at age five. Each measure retains its own published period, numerator, denominator and 95% confidence interval. A borough comparison describes recorded vaccination coverage; it does not explain why coverage differs, and suppressed values remain unavailable rather than becoming zero.

## Visualisations

- [Coverage map](https://londongraph.com/g/vaccination-coverage-across-london): Select either MMR measure while retaining exact vaccinated counts and eligible-child denominators.
- [Distribution](https://londongraph.com/g/vaccination-coverage-across-london?view=distribution): Place the selected borough coverage estimate around the London median and quartiles.
- [One dose vs two](https://londongraph.com/g/vaccination-coverage-across-london?view=dose-relationship): Compare the two differently aged MMR coverage measures without treating them as one cohort. Caveat: The measures refer to different ages and may have different eligible populations.
- [Borough detail](https://londongraph.com/g/vaccination-coverage-across-london?view=borough-detail): Inspect coverage, counts and denominators for both measures in one selected authority.
