<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">这是一种误读。癌症疫苗是“治疗性疫苗”，而非<span style="color: black;">咱们</span>小时候打的乙肝、小儿麻痹<span style="color: black;">这般</span>的“预防性疫苗”。一种疫苗，<span style="color: black;">常常</span>只对一种病原体有用。广谱的癌症预防疫苗不现实，<span style="color: black;">由于</span>癌症<span style="color: black;">并不</span>是一种病，而是<span style="color: black;">非常多</span><span style="color: black;">疾患</span>的统<span style="color: black;">叫作</span>——<span style="color: black;">每一个</span>人的癌症其实都不太<span style="color: black;">同样</span>。<span style="color: black;">因此</span>，直接打一针就啥癌症都不得的想法很美好，但不现实。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">非常多</span>人理解的疫苗，<span style="color: black;">便是</span>“预防性疫苗”：健康人打了疫苗，就能预防某种病。针对癌症<span style="color: black;">亦</span>是有<span style="color: black;">关联</span>的预防性疫苗的，<span style="color: black;">日前</span>有两种，即能预防肝癌的乙肝病毒（HBV） 疫苗（中国70%<span style="color: black;">上下</span>的肝癌和乙肝病毒<span style="color: black;">关联</span>）和能预防宫颈癌的人乳头瘤病毒（HPV）疫苗（99%的宫颈癌和人乳头瘤病毒<span style="color: black;">关联</span>）。但这两个疫苗严格<span style="color: black;">来讲</span>，应该算是病毒疫苗，并非“癌症疫苗”。它们<span style="color: black;">亦</span>只能预防癌症里很小一部分亚型。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">目前几乎所有在临床实验的癌症疫苗都是“治疗性疫苗”，它<span style="color: black;">能够</span>分为两大类，分别叫“肿瘤特异抗原疫苗”和“肿瘤<span style="color: black;">关联</span>抗原疫苗”。这些疫苗能够<span style="color: black;">帮忙</span>人体免疫细胞<span style="color: black;">精细</span>识别癌细胞，起到抗癌<span style="color: black;">功效</span>。“肿瘤治疗性疫苗”许多还在<span style="color: black;">实验</span>中，距离上市还有距离。</span></p><strong style="color: blue;"><span style="color: black;">2.密胺碗是“夺命碗”</span></strong>
