http://www.quackwatch.com/03HealthPromotion/immu/too_many.htmlImmune System Capacity Is Huge The currently recommended schedule—posted at the U.S. Centers for Disease Control and Prevention Web site calls for 5 live or weakened organisms and 21 different antigens by age 6. A few more are added from ages 7 to 18. The goal is to protect children as early as possible from diseases that are very dangerous to young children. The capacity of the immune system to respond to antigens is vast and far greater than most people realize. Experts estimate that humans can generate about 10 billion different antibodies [4] and that, due to exposures to germs and other foreign material, people make between 1 million and 100 million different antibodies during our lifetime [5]. The vaccine schedule produces a total of about 30 antibodies. It is also estimated that (a) each infant has the theoretical capacity to respond to about 10,000 vaccines at any one time and (b) if the 11 routinely recommended vaccines were administered together, the immune system would need to use only about 0.1% of its capacity to process them [6].
@赵宇空 赵先生你好!首先对你为华人做出的贡献表示感谢。相信这里大多数人也都可以看到你们团队的付出。朝阳她说话是比较辛辣,你一下子接受不了我可以理解。不过我觉得,你既然是社团领袖,有必要展现你的胸襟,昨天你贴出的@谈云识天气 攻击你的截图我看了,“shame on you"这样说心里肯定不好受,不过你上升到什么奴性,懦夫,我以为就不恰当了。
