California schools are paying a financial price for low vaccination rates. State data shows more than $2.2 million in funding was lost over two years because some students didn’t meet required immunization standards. Since school funding is tied to average daily attendance, districts with higher non-compliance saw money reduced. In 2023 and 2024, audits found over 10 percent of certain grade levels weren’t fully vaccinated, impacting schools in 72 districts statewide.
