The Arizona House has passed a resolution that would ban governments and schools from requiring vaccinations, sending it to the state Senate where approval is required. The measure, written by state Rep. Nick Kupper, would amend the Arizona Constitution to prohibit any government entity or school from imposing vaccine mandates as a condition of employment or access to services. If approved, the resolution would go directly to the November ballot, bypassing Gov. Katie Hobbs' veto power. Critics argue that the measure could accelerate a decline in vaccination rates already underway in Arizona, which has seen 275 measles cases since the start of 2025.
