Data file: vacc_data_selected_BEST

As there will be multiple records per child, the data are then reduced to have one line per child with the 'best' record for each vaccination, the criteria used to designate the best record are:
Vaccination date recorded
Vaccination date is not before birth date
Vaccination date fits with normal Malawian vaccination schedule and other vaccines in the series
The information on the vaccine was taken form the health record
Where there are multiple records meeting these criteria the earliest record is taken. Where there are none then the criteria are relaxed gradually so for each person the best possible record is taken.
As sometimes the vaccine is reported as received but no vaccine date is given the earliest interview date when it was reported as received is also included as part of the record.
This 'best' dataset is saved as vacc_data_selected_BEST.

In the variable labels (S) indicates that the variable is unchanged from the original source and (D) indicates that it is a 'derived' variable, often using more than one source variable. For both types information on where the data come from and how they are processed is found in the 'Recoding and Derivation' section
