Immunization Information For Providers


All children deserve to have a medical home. The Yolo County Health Department children's immunization staff work with families to help them access services through their child's primary care provider. If they do not have a PCP, we help them to find one.

Immunization Schedules



Maternal, Child, Adolescent Health

The mission of the Yolo County Maternal, Child, and Adolescent Health (MCAH) Program is to assure that pregnant women and their children are able to obtain quality maternal and child health services.

Child Health & Disability Prevention

The Child Health & Disability Prevention Program (CHDP) is a preventive program for infants, children, and teens that provides complete health exams and immunizations for Medi-Cal eligible children (ages 0 to 21) and moderate income children (ages 0 to 19) at no cost. Services in Yolo County are provided by enrolled physicians and community clinics. CHDP provides care coordination to assist families with medical appointment scheduling, transportation, and access to diagnostic and treatment services.
