瑞典卡罗琳医学院教授 Anders Sönnerborg认为,冠状病毒发生变异本身并不奇怪,但其危险在于如果病毒继续变异,可能会导致现在的疫苗变得不那么有效。如果新冠病毒进一步变异,到了秋季,肯定会需要新的疫苗。
尽管新型冠状病毒的变种毒株广泛存在于瑞典,但卡罗琳医学院教授、疫苗专家Matti Sällberg认为没有必要过分担忧,重要的是要谨慎,继续切实遵循瑞典卫生部的建议。他认为,研究表明,新冠病毒的变异已经发生,而且可能会非常普遍。所以,必须监测病毒的变化,监测是否会产生重大影响的意外突变。
Anders Sönnerborg 教授也认为,所有的病毒都会变异。但冠状病毒的变异程度似乎比艾滋病毒或丙型肝炎病毒要小得多。不过,他也指出,现在正处在瘟疫大流行期间,病毒有更多的机会在人体内变异,这意味着风险显然比当初预估的要高。根据他的说法,病毒有可能继续变异,从而会使目前的疫苗不再有效。但他也相信,有可能通过改变目前疫苗的部分设计,使其适应新的突变。
Matti Sällberg 教授也对未来对抗冠状病毒突变的疫苗持乐观态度。他说,现在重要的是要继续使用现有的疫苗,即使是变异的病毒,它们对人体也有一定的保护作用。
