Immunization prevents communicable diseases helping students stay healthy. MESD supports PPS in managing State-mandated immunization requirements (OAR 333-050-0010-0110) in partnership with Multnomah County Health Department. School staff are responsible to collect information about immunization. MESD inputs, analyzes and monitors immunization records in order to minimize the number of students excluded for vaccine-preventable diseases. This maximizes student attendance and learning time. Nurses, together with the MESD immunization team, assist families to navigate the health system to access resources for required vaccines.
