CDC Recommendations at This Level
Vaccination rates are critically low
- • Your state's MMR coverage is well below the herd immunity threshold
- • Outbreaks can happen when coverage drops this low — check the measles tracker for your state
- • Talk to your doctor about catching up on vaccinations if not up to date
- • Consider talking to your school or daycare about their vaccination policies
This is general public health guidance based on CDC recommendations — not personal medical advice. Talk to your healthcare provider about what's right for you and your family.

Frequently Asked Questions
What is the MMR vaccination rate in Idaho?
Kindergarten MMR coverage in Idaho is 78.5% for the 2024-25 school year. This is below the 95% threshold needed for herd immunity against measles.
Why is 95% coverage important?
Measles is extremely contagious. About 95% of a community needs to be vaccinated to prevent sustained transmission — this is called "herd immunity." When coverage drops below this threshold, outbreaks become more likely, putting unvaccinated individuals at risk.
What are vaccine exemptions?
Vaccine exemptions allow children to attend school without certain vaccinations. Medical exemptions are granted for children who cannot be safely vaccinated. Non-medical exemptions (religious or philosophical) vary by state law. Higher exemption rates are associated with lower coverage and increased outbreak risk.
