Disinfection & Safety第 23 / 100 题
Which best describes acquired immunity?
a.Protection a person is born with that resists all infection
b.Resistance developed after exposure to a pathogen or after vaccination
c.The body's physical barriers, such as unbroken skin
d.The ability of a disinfectant to kill spores
解析
Acquired immunity develops after the immune system encounters a pathogen naturally or through immunization, such as the hepatitis B vaccine. Natural immunity is what a person is born with, and unbroken skin is a component of that natural, non-specific defense. Spore-killing describes sterilization, not immunity.
