Vaccine Administration Management system properties

Vaccine Administration Management booking uses the following system properties. Users with the admin role can access the property settings by navigating to All > Vaccine Administration Management > Administration > Properties.

PropertyDescription
sn\_vaccine\_sm.enable\_appointment\_slot\_choice

Enable or disable appointment slot choice.

When set to true, users can choose the slot. When set to false, the system books an appointment automatically.

The default value is false.

sn\_vaccine\_sm.self\_booking\_slots\_fetched

Set the number of slots fetched by the system to book an appointment in user self-booking. The higher value reduces any chance of failed appointments in high concurrency scenarios.

The default value is 1.

Note: The system property only applies if the sn_vaccine_sm.enable_appointment_slot_choice value is false.

The default value is mi.

sn\_vaccine\_sm.vaccine.management.booking.max\_distance

Set the maximum distance, in miles, that is searched for an available vaccination location if there’s no appointment slot available at the user’s preferred center.

The default value is 50.

sn\_vaccine\_sm.vaccine.management.booking.max\_locations

Set the maximum number of alternate locations that are searched for a vaccination if there’s no appointment slot available at the user’s preferred location. A higher value for this property increases the time that it takes to complete mass booking.

The default value is 5.

Enable booking for all doses of the vaccine, for both mass booking and self-service, or enable booking for the first dose, with subsequent appointments booked after the first dose is administered.

When set to true, appointments are booked for all doses of the vaccine, both in mass scheduling and self-service. When set to false, only the appointment for the first dose is booked and subsequent appointments are booked only after the previous dose is administered.

The default value is true.

For more information about booking subsequent doses, see Book appointments for subsequent doses after a previous dose is complete.

sn\_vaccine\_sm.enable\_vam\_appointment\_config

sn\_vaccine\_sm.strict\_check\_lead\_max\_time

Display the time after which the first available appointment slot is shown to the user.

When set to true, slots for subsequent doses are calculated to accuracy, measured in seconds, using lead or max times. When set to false, the second slot can be booked at any time.

For example, if the first dose is administered on June 1, 5:00 PM and the lead time is 21 days, the second slot can be booked after June 22, 5:00 PM. However, if the property is false, the second slot can be booked at any time on June 22.

This system property affects mass booking.

The default value is true.
