COVID-19 Vaccination Data

Data for Broomfield’s vaccination dashboard is downloaded from the Colorado Immunization Information System (CIIS), a statewide immunization registry. Any provider in the state of Colorado can administer the dose and are supposed to enter data within 72 hours of the dose being administered. Doses are assigned to a county based on the patient’s address and are not dependent on where (i.e. which county) the vaccine was administered.

Data Definitions

The number of ‘Broomfield Residents Who Initiated Vaccination’ is the total count of residents who received a single dose of the Pfizer or Moderna COVID-19 vaccine, which are both a 2-dose vaccine and are not considered 'complete' until they receive the second dose. 

The number of 'Broomfield Residents Who Completed Vaccination’ is the total count of residents who have either received two doses of the Pfizer or Moderna COVID-19 vaccine or one dose of the Janssen vaccine.

Cumulative Doses Administered to Broomfield Residents is roughly the sum of people immunized with one dose and two times the number of individuals immunized with two doses. This discrepancy is a reflection of the challenges associated with collecting immunization data in real time. This difference may exist for numerous reasons, including but not limited to administered doses not entered into CIIS, data entry errors, delays in reporting, doses received outside of Colorado, or more than 2 doses received.
