Immunization rates

Updated 2/19/20

Vaccinations can reduce the number of children who contract severe illnesses and prevent the spread of vaccine-preventable diseases later in life. The national Healthy People 2010 goal was 80% of all two-year old children immunized. In the early 1990s, the immunization rate for Nevada was under 40% for 2-year olds. Now it is over 60% for current federal standards but will require a great deal more effort. Nevada continues to have one of the lower immunization rates in the nation. The Nevada Immunization Coalition is committed to turning things around and sorting out their major barriers to reaching the children of Nevada.
