Frequently Asked Questions
What is the MMR vaccination rate in Maine?
Kindergarten MMR coverage in Maine is 97.6% for the 2024-25 school year. This meets the 95% herd immunity threshold.
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.
