What would be a primary advantage of passive immunity with diseases such as tetanus or botulism?
A. Time. You can quickly neutralize the toxin with a passive administration of antibodies to save the patient's life when none is available for them to make their own active immune response. B. Cost. It's far cheaper to administer a dose of antibodies harvested from the serum of an actively immunized animal or human than it is to administer a vaccine. C. Safety of delivery. It's far safer to administer a dose of antibodies harvested from the serum of an actively immunized animal or human than it is to administer a vaccine. D. Handling of treatment. It's difficult to keep vaccines stored properly to keep their potency, especially in Third World countries without adequate "cold chains" for transport into jungles and deserts. It's much easier to keep a batch of antibodies stable, even in extremes of heat and humidity.
