Why it matters

Annual and multi-year figures move slowly. A step this size is compared with how far the same series usually moves from one period to the next, so an ordinary year does not read as news.

For full immunisation coverage, higher is better. This movement is therefore assessed as an improvement.

Historical context

Compared with the previous round, 2019–21. Survey rounds are years apart, so this is a change between rounds, not a recent movement.
