Whether a date of vaccination was recorded on the health card for Polio 0 (at birth). Code 1 means the child has a date recorded for the vaccination.

Code 3 is used to indicate situations where the health card is clearly marked to indicate that the vaccination was given, but no date was recorded on the health card for the vaccination.
