(1/2) MMWR: Measles Outbreak Linked to Air Travel — Colorado, 2025
An unvaccinated traveler exposed others during an international flight and at Denver International Airport, leading to:
• 9 secondary & 1 tertiary case in Colorado
• 7 more cases in other states
• 4 hospitalizations, mostly unvaxxed

The plan, which is not finalized, suggests children get fewer shots and shifts to a model telling parents to consult doctors to make their own vaccine choices.
