FOOTNOTES
Instructions: On the chart locate the student’s age or grade and read from left to right on the chart to determine the NUMBER
of required vaccinations by age or grade. Dosing or spacing intervals should not be considered when determining if the
requirement is met, only count the number of doses needed. MMR and Varicella vaccination dates should be evaluated (See
footnote #4).

If DT vaccine is given in place of DTP or DTaP, a physician documented medical contraindication is required.
2.
Proof of immunity by positive blood test is acceptable in lieu of vaccine history for hepatitis B, polio and measles, mumps,
rubella and varicella, but revaccination may be more expedient.
