Pima County launches mobile vaccination units for MMR immunizations in under immunized schools

The Pima County Board of Supervisors convened on June 3, 2025, to discuss a critical mobile vaccination plan aimed at addressing low immunization rates for measles, mumps, and rubella (MMR) in local schools. With no reported cases of measles in Arizona, health officials are proactively preparing to prevent potential outbreaks by deploying mobile vaccination units to schools with immunization rates below the 95% threshold necessary for herd immunity.

Dr. Cullen, the director of the Pima County Health Department, presented the plan, which focuses on schools and childcare facilities identified as having low vaccination coverage. The initiative aims to increase MMR vaccinations while also educating parents about the importance of immunization. The health department will prioritize outreach to schools with the lowest vaccination rates, ensuring that families have access to vaccinations and the necessary information to make informed decisions.

The plan is set to begin outreach on July 1, 2025, with mobile units visiting schools to provide vaccinations. Schools will be contacted to gauge interest in hosting these clinics, and parental consent will be required for any vaccinations administered. The health department emphasized that no child will be vaccinated without appropriate consent, and schools will not be entered without prior approval from administrators.

In addition to the vaccination plan, the board discussed the importance of addressing vaccine hesitancy, particularly in light of the mistrust that arose during the COVID-19 pandemic. Dr. Cullen noted that one-on-one conversations between parents and healthcare providers are crucial in alleviating concerns and encouraging vaccinations.

The meeting also touched on the issue of exemptions, with Dr. Cullen explaining that while vaccinations are required for school enrollment, parents can document exemptions for medical, personal belief, or religious reasons. The health department is committed to reducing barriers to vaccination and ensuring that all children have the opportunity to be immunized.

As the school year approaches, the Pima County Health Department is taking significant steps to protect public health and prevent the spread of vaccine-preventable diseases. The mobile vaccination plan represents a proactive approach to safeguarding the community's health and ensuring that children are protected as they return to school.
