General MicrobiologyAdoptive immunization involves the transfer of readymade immune cells, such as antibodies, from a donor to a recipient. Tetanus immunization is typically achieved through active immunization with the tetanus toxoid, which induces the body to produce its own antibodies against the tetanus toxin. Passive immunization, on the other hand, is achieved by injecting tetanus antitoxin, which provides immediate but temporary protection by neutralizing the toxin in the recipients body. The statement is incorrect because tetanus toxoid is used for active immunization, not adoptive immunization.
