The body's ability to prevent and control infections primarily involves the immune system's production of antibodies, rather than solely relying on the production of antitoxins. Antibodies are specialized proteins that identify and neutralize pathogens such as bacteria and viruses. When the immune system encounters an infection, it generates specific antibodies that bind to the invading pathogens, tagging them for destruction by other immune cells or neutralizing their harmful effects directly.

Additionally, proper hygiene plays a crucial role in infection prevention by reducing the likelihood of exposure to pathogens. Isolating sick individuals can also help prevent the spread of infection, but the primary mechanism of the body's response is through the adaptive immune response, which includes antibody production. Antitoxins may be relevant in specific contexts, particularly in response to certain toxins produced by pathogens, but they are not the primary method by which the body controls infections overall. Thus, the most accurate response to how the body prevents and controls infections is through the production of antibodies.
