The Oklahoma Caring Van Program delivers immunizations to protect children and adolescents from dangerous illnesses at no cost to their families. The Oklahoma Caring Van Program is uniquely designed to eliminate barriers that commonly prevent children from receiving on-time, age-appropriate immunizations in traditional health care settings.

Since the program began in October 1999, thousands of children have received immunizations from registered immunization nurses aboard the Caring Vans. Immunization information is entered in the Oklahoma State Immunization Information System (OSIIS) so children's vaccine history is readily available.
