Catalogue description: [Annual infant immunisation coverage rates at national level.](https://data.gov.my/data-catalogue/infant_immunisation).

## Coverage

The dataset covers Malaysia (national) from 2000-01-01 through 2023-01-01.

## Schema

| Field | Type | Description |
| --- | --- | --- |
| `date` | date | The year of the immunisation data in YYYY-MM-DD format, with MM-DD set to 01-01 because the data is annual. |
| `disease` | string | The disease for which immunisation coverage is reported, such as measles, MMR, DPT, Hepatitis B, or polio. |
| `rate` | number | The immunisation coverage rate as a percentage. |

## Known quirks

- Annual dates use 1 January.
- Coverage rates can exceed 100% because aggregate immunisation counts use official population estimates as the denominator.
- Measles data ends after the transition to MMR, and eight rate values are blank.

## Breaking changes

None observed.

## Reproducibility

curl -sS --max-time 30 \
