Reports on discrepancies between local and systemic immunity started to appear about 50 years ago (cf. 1968). Protection against infections has been shown in many cases to be closely related to the antibody content of external secretions and more or less independent from the serum antibody level.
关于局部免疫和全身免疫之间差异的报告大约在50年前开始出现(参见1968年)。在许多情况下,已表明对感染的保护与外分泌液中的抗体含量密切相关,并且或多或少独立于血清抗体水平。
