p-Value calculated using aggregate binary logistic regression, statistically significant changes in uptake compared to 2019 are shaded green. p-Value rounded to 2 decimal places.

CI, confidence interval; LD, lockdown; MMR, measles, mumps, and rubella; NA, not applicable; OR, odds ratio; Post LD, postlockdown; Pre LD, prelockdown.
