Why This Indicator Matters

Vaccinations are a crucial defense for the health of all communities and our economy. Since their creation, vaccines have saved millions of lives. When the vast majority of a community is vaccinated for a particular disease and reaches “herd immunity,” it can prevent or stop the spread of infection. Based on research, the minimum immunization rate to reach herd immunity for different diseases ranges from 80% to over 90%. This is why any decline in vaccination rates is a threat to our most vulnerable, who may be unable to get vaccinated—like babies who aren’t old enough or children with weakened immune systems.  A majorly vaccinated community protects everyone, including adults and those who appear healthy.
