Colorado requires all students to be immunized per the vaccine schedule established by Colorado Board of Health rule 6 CCR 1009-2, upon school entry. The purpose of the immunization requirements for school entry is to protect students, staff, and the visiting public against vaccine-preventable diseases within schools.

The Colorado Department of Public Health and Environment is proposing amendments to this rule that encompass three objectives. These objectives, along with the rulemaking process and opportunities for public comment and participation are outlined in this letter.
