@ Griff 听上去你是专家。 今天刚出来的新闻The BA.2 subvariant of the Omicron coronavirus variant, which has quickly taken over in Denmark, is more transmissible than the more common BA.1 and more able to infect vaccinated people, a Danish study has found.

Omicron BA2 对接种的人群比BA1更有传染性。 你这怎么分析？ 病毒的自然生存就是每时每刻复制来寻求生存， 在复制过程中出现变异， 有些变异优化而得以继续生存有些变异反而导致病毒自身毁灭。 能生存下来的是它的自身变异优化。 那你说短短时间就出现新变种，人人是不是真的一月打一针呢。
疫苗分分秒秒变种是科学。 认为人的疫苗开发能赶上病毒的自然复制变异那是痴人说梦话。 所以我不相信疫苗。 你最终还得靠你的身体的自身自然免疫去应对变异。 身体是个很微妙的生物系统， 要不然人类早就在几千年前灭种了。 当然现在的医学可以让人类可以有更好的保护但只是在人类的现有的能力之内， 医学不是万能的。 能好好活着更多的取决于你的平时饮食起居心情运动还有遗传基因。
The study also showed that BA.2 was relatively better than BA.1 at infecting vaccinated and booster-vaccinated people, indicating greater "immune evasive properties" of the subvariant.But vaccines still played an important role, the study underlined, since both booster-vaccinated and fully vaccinated individuals were less like to get infected and transmit either subvariants, compared to those not vaccinated.
都是一个Omicron谱系，这对比是说，BA.2比BA.1更具有免疫逃逸，没说疫苗无效——疫苗会随着变异点变换/增加而变化/减弱，这是常识不难理解吧。红字部分看一下吧，结论是疫苗再被击破，也比没接种疫苗的好。
He is fully vaccinated thats why he is not feeling a thing. Like the flu shots, we can still catch a flu but serious complications will be reduced. I don’t understand why people think vaccination will prevent them from catching COVID. Maybe the government hasn’t done a good job conveying the right message. However, I agree that vaccination shouldn’t be mandatory as people have the freedom of choice. However, employers also have the freedom of choice to hire vaccinated employees only.
