Wright is to render the bacteria in the tissues less able to resist the attacks of the phagocytes. This is done by injecting specially prepared dead cultures of the causative organisms while the disease is still active. </s>"

"<s>[INST] Source:8989REF How does the vaccine treatment work when the vaccine is prepared from organisms isolated from the patient himself? [/INST] Source:8989REF When the vaccine is prepared from organisms isolated from the patient himself, it is most successful. This is because the vaccine is able to stimulate the patient's immune system to produce antibodies that are specific to the organisms, which can help to neutralize their toxic effects. </s>"
"<s>[INST] Source:8989REF What is the relationship between anaphylaxis and phagocytes? [/INST] Source:8989REF According to the passage, anaphylaxis is caused by the attacks of phagocytes. Phagocytes are cells that engulf and digest foreign substances, including bacteria. In the context of anaphylaxis, the phagocytes are overactive and can cause severe toxic symptoms. </s>"
"<s>[INST] Source:8989REF What is the significance of the fact that the vaccine is most successful when the vaccine is prepared from organisms isolated from the patient himself? [/INST] Source:8989REF The significance of this fact is that it highlights the importance of using the patient's own organisms when preparing a vaccine for anaphylaxis. This approach allows the vaccine to stimulate the patient's immune system in the most effective way possible, by using organisms that are specific to the patient. </s>"

"<s>[INST] Source:8989REF Why should vaccines not be given to patients in a negative phase? [/INST] Source:8989REF A certain amount of the opsonin in the blood is used up in neutralizing the substances injected, and this may reduce the opsonic index to such an extent that the vaccines themselves become dangerous. </s>"
