Antibody produced in one person or animal and transferred to another gives which kind of protection?

1. Passive immunity is protection by antibody or antitoxin made elsewhere and given to the recipient. 2. Because the antibody is already made, protection begins at once. 3. Because the recipient's own immune system was never stimulated, the antibody degrades over weeks to months and protection ends. 4. Lifelong protection follows active immunity instead, where the person's own immune system responds. _Source: CDC Epidemiology and Prevention of Vaccine-Preventable Diseases (Pink Book), section Passive Immunity_
