Notes

Note that, in the covid19_vaccination Data Portal table from which these data are derived, there are a small number of participants with multiple vaccination records on the same date. For this summary field, these records have been condensed into single instances per date and participant.

Please note that this field is only available for research related to COVID-19; principal investigators must contact the Access Management Team to request authorisation to access the data.

Coding 819 defines 6 special values:

1900-01-01 represents "Code has no event date"

1902-02-02 represents "Code has event date matching participant's date of birth"
1903-03-03 represents "Code has event date after participant's date of birth and falls in the same calendar year as date of birth"
