The goal of active immunotherapy is to stimulate the immune system to fight disease, particularly cancers and certain infectious diseases. This approach involves training the immune system to recognize and attack cancer cells or pathogens effectively. Active immunotherapy can include vaccines designed to elicit a strong immune response against specific antigens present on the surface of cancer cells. By enhancing the body's immune response, active immunotherapy aims to achieve long-lasting protection against the targeted disease and improve overall survival rates.

The other options describe different therapeutic approaches. Passive immunity relies on the administration of external antibodies and does not activate the patient's immune system to produce a broader immune response. Delivering chemotherapy directly to cancer cells focuses on cytotoxic effects rather than utilizing the immune system. Nourishing hematopoietic stem cells addresses cell growth and development, which is not the primary aim of immunotherapy. Thus, the correct choice highlights the fundamental role of active immunotherapy in harnessing and enhancing the body’s own immune mechanisms for therapeutic purposes.
