Colorado law requires all students attending Colorado schools to be vaccinated against certain diseases, unless an exemption is filed. Meeting the initial vaccine requirements does not excuse a student from meeting additional requirements.

For the most current immunization information, see the Colorado Department of Public Health & Environment (CDPHE) website
