school immunizations; exemption; adult students

HB 2058 would have expanded Arizona's school immunization exemption rules to allow students aged 18 and older to submit their own signed statement declining vaccines based on personal beliefs, instead of requiring parental consent. This change directly affects adult students (18+) in Arizona public schools who wish to opt out of required immunizations. The bill maintained existing requirements for medical exemptions (requiring physician certification) and kept the rule that students without immunization proof must stay home during disease outbreaks. However, the bill was vetoed by the governor on April 15, 2025, so it did not become law.
