Why This Indicator Matters

Kindergarten-entry vaccination requirements have played an important role in controlling vaccine-preventable diseases in the United States.  In 2019, Maine passed a law by referendum requiring school children receive vaccinations, which took effect in September 2021. The new law allows for exemptions to required vaccinations only for medical reasons and not for religious or philosophical reasons,  If more kindergartners are vaccinated the chance that disease will spread through schools and communities is lessened. Achieving a 95% or higher level of vaccinations provides more protection against the spread of diseases than lower rates.

What the data shows
The kindergarten exemption rate in October 2022 was under 1 percent- 0.9% compared to 4.6% year before the law took effect. The number of kindergarten exemptions dropped from 523 before the law, to 95 for the latest year. For the 2022-2023 school year, every county easily achieved the 95% vaccination rate and had kindergarten exemptions below 5%, with the highest rate being 2.3% in Knox County.
