ExIS Functionality
The VTrckS ExIS (External Information System) interface is a means for grantees to upload provider master data, inventory data, and vaccine requests from their Immunization Information System (IIS) to VTrckS. ExIS also allows the grantee to download shipping information from VTrckS to import into their IIS.
ExIS grantees already rely on their IIS to collect and consolidate data from vaccination providers and to sustain effective immunization strategies through the use of clinical decision support, vaccination coverage reports, interoperability with electronic health record systems, vaccine inventory management, and reminder/recall messages. Adding IIS ordering functionality as part of an interface between VTrckS and the IIS builds on existing relationships with providers and provides an additional incentive for vaccination providers to participate in IIS while promoting greater accountability of publicly purchased vaccine.
Here is an overview of the process:

ExIS Benefits in VTrckS
There are additional benefits for ExIS users in VTrckS. Users will be able to:
- Create multiple orders from a single file upload
- Receive shipment data for both direct and non-direct ship orders
- Analyze data using SAP Business Objects reports if their IIS does not already have needed reporting capabilities
Providers Ordering Through ExIS
Providers that order through their grantee’s ExIS will not have access to VTrckS.
- Providers will continue to place vaccine requests as they do today
- No identify-proofing or VTrckS provider training is necessary
ExIS grantees can export a file with shipment information from VTrckS, as well as continuing to receive the shipment data file from McKesson. Please note that the shipment data file contains information for both non-direct and direct ship vaccine. Providers who have trouble accessing the grantee’s IIS will need to contact the grantee for assistance.
ExIS Provider Returns, Transfer, Wastage or Order Changes
The VTrckS ExIS interface does not handle returns, transfers, wastage, or order changes. The grantee will enter these transactions directly into VTrckS.
ExIS Specifications in VTrckS
The ExIS interface needs to meet the VTrckS ExIS specifications, including CSV file formatting, NDC, lot number inventory reporting, and other reporting requirements. CDC will inform the grantee with information regarding the ExIS technical requirements.
