Q72. In 1902, Pаul Pоrtier аnd Chаrles Richet cоnducted experiments tо develop a vaccine against the actinotoxin produced by the Portuguese man-o'-war (Physalia physalis). Their protocol involved administering a small dose (0.1 mL/kg) of actinotoxin to dogs, followed by a larger bolus dose several weeks later. They hypothesized that this regimen would confer protective immunity against the toxin. In their experiment, eight dogs received the initial small dose without incident. However, when given the larger bolus dose weeks later, all eight dogs rapidly developed severe symptoms, including difficulty breathing, vomiting, and loss of consciousness, leading to death within minutes. Which best explains the mechanism responsible for the dogs' fatal reaction to the second dose of actinotoxin?
