Description: The Colorado Immunization Information System (CIIS) can estimate immunization uptake and track vaccination coverage levels over time. This data includes routine immunization rates calculated for 19-35 month old children and 13-17 year old adolescents in Colorado. To correct for active records in CIIS with out of date address information who likely no longer live in Colorado, 19-35 month olds are included in rate calculations if they have at least two non-COVID-19 and non-flu visits on record in CIIS before nine months of age. A visit is defined as a distinct date of immunization services. Adolescents are included in rate calculations if they have received at least one non-COVID-19 vaccine in the past five years.
Routine immunization coverage rates are based solely on information available in CIIS. CIIS is a mandatory reporting system; vaccine providers are required by law to submit both immunization and exemption information to CIIS. Rate estimates are highly dependent on the completeness and accuracy of the data in CIIS. The widest variation in rates is typically seen in smaller counties, where fewer children and adolescents are included in rate calculations.
Routine immunization rates calculated for 19-35 month old children include 1+ doses of MMR, 1+ Varicella, 3+ Hepatitis B, 3+ Hib, 3+ Polio, 4+ DTaP, 4+ PCV, and the seven-antigen series (4:3:1:3:3:1:4). Routine immunization rates calculated for 13-17 year old adolescents include 1+ doses of MenACWY, 1+ Tdap, up-to-date status for HPV overall, up-to-date status for HPV for males, and up-to-date status for HPV for females. Rates are provided at the state and county level. Rates are updated twice annually, and are available starting from the six month period spanning from July 1, 2015 through December 31, 2015. For each six month period, child or adolescent age is defined as of the beginning of the six month period. Immunizations administered and reported to CIIS as of the end of the six month period are included in rate calculations.
Here is a brief description of the individual data fields (columns) included in this dataset:
- county: This field contains the geographic level of the corresponding rate. For state-level rates, ‘county’ is set to “COLORADO”. For county-level rates, ‘county’ corresponds to the Colorado county name (character).
- vaccine: This field contains the vaccine of the corresponding rate (character).
- percent: This field contains the percentage of children or adolescents who have received the corresponding number of doses of the vaccine in CIIS (numeric, three digits).
- starting_date: This field contains the beginning date of the six month time period (date, yyyy-mm-dd).
- time_period: This field contains a description of the six month time period (character).
- group: This field describes the age group of the corresponding rate (“19-35 month olds” or “13-17 year olds”) (character).
- publish_date: Data that this dataset was published to the CDPHE Open Data Portal.
