Overview

• The campaign launched in mid-August with events at book bag giveaways and schools across suburban and urban areas to encourage timely MMR vaccinations for children.
• Mobile outreach units will focus on marginalized neighborhoods and communities of color to reach families with limited access to clinics.
• Health data show over 1,300 measles cases nationwide this year—including 10 in Cook County—while kindergarten MMR coverage has dipped to about 92.5%.
• Officials report that the number of unvaccinated students in suburban Cook County has doubled over the past decade, undermining the 95% threshold needed for herd immunity.
• Leaders emphasize that two doses of the MMR vaccine offer roughly 97% protection and are actively countering social-media misinformation to reassure parents about safety.
