BCG是世界范围内最常接种的疫苗之一,它除了对结核病(TB)有预防作用外,研究表明,接种BCG还具有许多额外、有益的非特异性免疫效应,包括在高死亡地区降低由非TB引起的婴儿和儿童的整体死亡率。接种BCG引起的抗体应答,为研究BCG影响非相关抗原引起的免疫应答提供了机会。本研究比较了常规接种对已接种BCG和没有接种BCG的婴儿的抗体应答水平的影响。已接种BCG的婴儿来自于出生后就接种BCG的相关研究组,没接种BCG的婴儿来自于接种门诊。所有婴儿依澳
BCG, one of the most commonly vaccinated vaccines in the world, not only has a preventive effect on tuberculosis (TB), but also shows that BCG vaccination has many additional and beneficial nonspecific immune effects including reducing the risk of non-specific The overall infant and child mortality rate due to TB. Inoculation of BCG-elicited antibody response provides an opportunity to investigate the impact of BCG on non-related antigen-induced immune responses. This study compared the effect of routine vaccination on antibody response levels in infants with and without BCG. Infants who had been vaccinated with BCG came from the relevant study group who were born with BCG after inoculation, and those who did not receive BCG came from the vaccination clinic. All babies according to Australia
