Which of the following is/are (an) example(s) of passive immunity?
The correct option is D All of the above
Passive immunity is the transfer of antibodies generated in a person, to another individual. This confers the recipient with immunity to a disease that the person has not encountered. Passive immunity is naturally transferred to breast-fed babies from their mother's milk. Breast milk has colostrum that contains antibodies against pathogens the mother has been exposed to. Transfer of antibodies that occurs from mother to foetus via the placenta is also an example here. Yet another application of this type of immunity is in the case of snake bites or other poisoning, wherein the immunity has to be conferred immediately and hence, readymade antitoxins are administered to confer passive immunity.
