Autologous vaccines are created from a patient’s cancer cells, which are isolated from a blood sample. The cancer cells are cultured (effectively grown) in the laboratory, where they are combined with an immuno-stimulant designed to stimulate the body’s immune system into action. The disrupted cancer cells, now called tumour cell antigens, are re-administered into the patient through a vaccine. They provide the immune system with the blueprint to eliminate any remaining cancer cells in the body. The vaccine enables the body’s immune system to target and destroy cancer cells while leaving healthy tissue untouched.
