How does it work?它如何工作？ of Immunisation对接种疫苗

The immune system works to protect the body from potentially harmful organisms, such as bacteria and viruses. We are all born with some degree of protection (this is called innate immunity), which is provided by physical barriers to infection such as the skin.免疫系统的工程，以保护身体不受潜在有害生物，如细菌和病毒，我们都是出生，具有一定程度的保护（这就是所谓的先天免疫） ，这是所提供的无形壁垒，使感染，如皮肤。 Antibodies against infection are also passed from mother to baby through the placenta during development in the womb and through breast milk.抗感染，也通过了由母亲传染给婴儿通过胎盘发育过程中在子宫中，并通过母乳。 However, some of the natural immunity that we are born with starts to wear off as the immune system develops fully. Also, innate immunity does not protect us against all the organisms that cause disease.不过，一些自然免疫力，我们出生开始磨损小康作为免疫系统的发展充分。此外，先天免疫不保护我们对所有生物体造成的疾病。

When organisms overcome the defences of the innate immune system, your body responds by fighting each type specifically.  It retains a memory of each organism ‘fought’ so that its response is even more efficient next time the organism invades your body.当生物体克服部队的先天免疫系统，你的身体作出反应，争取每类具体，它保留了记忆的每一个有机体â € 〜 foughtâ € ™ ，以免其反应是更有效率下一次生物体侵入你的身体。 To do this it creates antibodies that recognise the disease and are ready to fight it.为此，它创造了抗体，认识到疾病，并准备争取。 You are then said to have ‘acquired immunity’ to the disease in question.  This usually means a much milder effect on the body, or none at all, should you come into contact with the disease again.然后，您说有â € 〜后天immunityâ € ™该疾病的问题。这通常意味着一个较温和的影响，对身体的，或没有在所有，您应该接触到这种疾病。

Without vaccination, it can take days or weeks to acquire immunity to a particular disease. During this time, you can become seriously ill, and may even die. An vaccination programme introduces enough tiny quantities of disease to encourage the body to create antibodies quickly.没有注射疫苗，可以采取数天或数周获得免疫力，以某一特定的疾病。在这段时间内，你就可以成为重病，甚至可能死亡。 1防疫注射计划，介绍了足够的微小数量的疾病，以鼓励机构，以创造抗体迅速。
