Antitoxic immunity，also known as specific immune response, is a kind of immune response which involves the production of antibodies that can neutralize or destroy specific toxins or toxic agents. Generally, antitoxic immunity is mainly acquired by direct exposure of an individual to the toxin, such as through injection of the toxin into the body or through ingestion of the toxin.

In most cases, the individual’s body produces antibodies to counteract the toxin, resulting in neutralization or destruction of the toxin so that it is no longer harmful. This process of immunity is called active immunity, as the body actively produces the antibody itself and acquires immunity.

Active immunity is usually long lasting and may even last for life. On the other hand, passive immunity does not involve production of antibodies by the individual’s body and instead involves the transfer of antibodies from one individual to another. Passive immunity is usually short-lived and lasts for only a short period of time.

One example of how antitoxic immunity works is in the case of vaccines. Vaccines are made using a weakened or dead form of the virus or bacteria they are designed to protect against. As the body is exposed to the weakened virus/bacteria, it produces antibodies specific to that virus/bacteria. This provides long-term protection against the virus/bacteria and helps to protect individuals from getting the disease in the future.

In summary, antitoxic immunity is a kind of immunity which involves the production of antibodies that can neutralize or destroy specific toxins or toxic agents. This type of immunity can be acquired either through active or passive methods, with active immunity usually being more long-lasting. Vaccines are an example of how antitoxic immunity can provide long-term protection against certain harmful pathogens and help protect individuals from future disease.
