Frequently Asked Questions
What is the MMR vaccination rate in South Dakota?
Kindergarten MMR coverage in South Dakota is 90% 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.
