According to the Colorado Department of Public Health and Environment, all vaccine providers must report all administered vaccines into the Colorado Immunization Information System (CIIS), a lifelong immunization record tracking system created by the Colorado Immunization Registry Act of 2007.
CDPHE says it will randomly assign a number to each eligible person in the CIIS database and then give those numbers to the Colorado Lottery to conduct the drawing. No personal health information will ever be disclosed to Colorado Lottery.
However, some KRDO viewers have reported that they've received a COVID-19 vaccine and didn't find themselves listed in the CIIS database. We've reached out to the state with questions about the discrepancy.
