For CIIS access, you must first take a required online course on CO.Train. To access and register for a CIIS course on CO.Train, please see our CO.Train Quick Guide here. Please see the chart below to find the course required for your type of user. This chart is also available in the Quick Guide. As listed in the chart, VFC Providers may need to take additional online courses to access the CIIS Inventory and Ordering Module. If you have questions about which course is right for you, please contact the CIIS Help Desk at 303-692-2437, option 2 or firstname.lastname@example.org.
