D
Feedback:
An antitoxin is an example of passive immunity. Antitoxins contain antibodies to very specific toxins. The antibodies are injected into the system and react with invading pathogens. Active immunity occurs when the body recognizes a foreign protein and begins producing antibodies to react against that specific protein or antigen. Vaccines are immunizations containing weakened or altered protein antigens that stimulate formation of antibodies against a specific disease. They are used to promote active immunity. Antivenin is used to refer to immune sera that have antibodies to venom that might be injected through spider or snake bites.
