Vaccines for Children (VFC) Tracking

IWeb and WIR can track both VFC vaccinations administered and vaccine lot inventory for providers. The following information is required to support this functionality:

Vaccine Lot Number
Vaccine Manufacturer
VFC Status (of patient at time of vaccine administration) or Vaccine Publicly Supplied (Yes or No)
(IWeb) Facility/Clinic ID (if the organization includes multiple facilities/clinics)
(WIR) Site ID (if the organization includes multiple sites)

VFC status must be transmitted in an OBX segment. The following is an example of how this is sent:

OBX|1|CE|64994-7^VACCINE FUNDING PROGRAM ELIGIBILITY CATEGORY^LN|1|
VO2^MEDICAID^HL70064||||||F|||20150202|||VXC40^ELIGIBILITY CAPTURED AT
THE IMMUNIZATION LEVEL^CDCPHINVS

For IWeb integration, the HL7 interface (profile) must be configured to "Update Registry Inventory" before submitting data (Import Profile > Update Settings section > Vaccinations tab). Currently configured lot numbers are decremented if they match the incoming vaccine code exactly. If the lot number is sent with a typo or the VFC status is incorrect, then the correct lot number may not be decremented and no error message is displayed. It is important to correctly configure the current lot numbers and to transmit the vaccines given without typos. In addition, since lot numbers may be tracked separately for each facility, the facility MUST be designated if lot numbers are defined by the facility.

For WIR integration, the parameter that controls vaccine lot decrementing is in WIR as part of site maintenance. Although coded fields must also match exactly with WIR, the validation step (in WIR) reports errors.
