× The federal government has shut down due to the failures of the President and Congress to continue government funding. Millions of Californians receiving benefits from state programs may be impacted. For now, California’s Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) will continue to provide services and enroll eligible families as long as funding is available. No new federal funding to California WIC will be provided until the President and Congress take action. Families should continue to use their WIC benefits and attend their WIC appointments. This information is subject to change, so please monitor the California WIC website for updates.

Please be wary of potential highly partisan political messaging while visiting federal government websites for information related to the federal government shutdown.

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.
