All Required Vaccines Rate FAQs

What is the All Required Vaccines (ARV) Rate?

The ARV Rate (formally known as the UTD Rate) is the percentage of students in a school or child-care facility that received all required vaccines.

How is the ARV Rate calculated?

The ARV Rate (the percentage of students fully-vaccinated)  =  (Number of Students with All Required Immunizations/Number of Students Enrolled) *100

Why is the ARV Rate much lower than each vaccine-specific rate, e.g. DTP Rate?

The ARV Rate is an overall measure of fully-vaccinated students.  The ARV Rate is always lower than the lowest vaccine-specific rate, e.g. DTP Rate, since it is a measure of overall school/facility vaccination status over multiple vaccines.  See table below illustrating this.
