现代生物技术的飞速发展，使传统的疫苗生产方式发生了根本的变化。疫苗研究领域变得异常活跃，从而使新型载体蛋白不断被发现，其作用机制得到全面研究。寻找安全、有效的载体蛋白是目前疫苗领域的课题之一。近年来的初步研究结果为载体蛋白的应用展现了广阔的前景。此文阐述了载体蛋白的作用机制和几种常用的载体蛋白。

 With the development of modern biotechnology, the traditional vaccine production methods have changed fundamentally. The field of vaccine research has become so active that new carrier proteins have been found continuously and its action mechanism has been elucidated. Looking for safe and effective vaccine carrier proteins are one of the subjects of the vaccine area currently. Preliminary results of the research in recent years demonstrated broad  prospects for carrier protein application. This article summarizes the action mechanism of carrier protein and several commonly used carrier proteins.
