请教下面这个关于疫苗和病毒变异的观点， 怎么理解？ 多谢！

" in minutes from its July 7 meeting, SAGE scientists wrote that "the combination of high prevalence and high levels of vaccination creates the conditions in which an immune escape variant is most likely to emerge." It said at the time that "the likelihood of this happening is unknown, but such a variant would present a significant risk both in the UK and internationally."

所有跟帖： 

• 一直不喜欢不列颠人，太绕。坦率地讲，无论谁说的都可能有问题、不准确，需要更多的时间来观察、验证。 -fuz- ♂ (0 bytes) () 08/01/2021 postreply 10:47:08

• 告诉你事实：去年十月份在印度首次测到delta变种，那时候还没开始打疫苗。扯啥免疫逃逸啊！ -fuz- ♂ (0 bytes) () 08/01/2021 postreply 11:03:06

• 印度已经成功靠药物降下来了，接种率只有6%。这正是一个可学习的例子。不是所有病毒靠疫苗解决的 -voice123- ♀ (0 bytes) () 08/01/2021 postreply 11:06:05

• 刚吃过饭在喝茶，看到这儿，喷了。能透漏点消息，印度用的啥药么？还有，在哪儿能淘到啊，得赶紧备上 -fuz- ♂ (0 bytes) () 08/01/2021 postreply 11:23:05

• 试着回答 1，病毒变异是病毒生存的本能，2. 所谓的“免疫逃逸“ -pickshell- ♀ (1453 bytes) () 08/01/2021 postreply 16:37:18

• 嗯，有这可能。“物竞天择，适者生存，优胜劣汰” 对病毒也适用。机会与强度，淘汰与存活。 -pickshell- ♀ (150 bytes) () 08/02/2021 postreply 04:17:57
