The Colorado Immunization Information System (CIIS) collects immunization information for Coloradans of all ages. Local WIC agencies can access this information. Along with letting you quickly view a child's vaccine record, CIIS:
  • Provides proof of ID (infant or child only). CIIS records may be used as proof of ID if vaccine records are present.
  • Saves time. It can help WIC clients provide vaccine records at appointments.
  • Shows recommended and overdue vaccines.
  • Supports efforts to refer clients to a health care provider for recommended vaccines.
