Footnote: Years presented are the final year of a school year (e.g., 2015-16 is shown as 2016). Data are aggregated from school-level data, which are reported for schools with 10 or more students enrolled in kindergarten. All required immunizations include 5 doses of DTP/DTaP/DT vaccine (4 doses meets the requirement if at least one was given on or after the fourth birthday); 4 doses of polio vaccine (3 doses meets the requirement if at least one was given on or after the fourth birthday); 2 doses of MMR vaccine (may be given separately or combined, but both doses must be given on or after the first birthday); 3 doses of hepatitis B vaccine; and 1 dose of varicella vaccine (or physician-documented varicella disease history or immunity). LNE (Low Number Event) refers to percentages that have been suppressed because fewer than 20 children had all required immunizations. N/A means that data are not available.
