Again, that's obviously a big question and how about the risk of reinfection.

这显然是一个大问题。以及再感染的风大吗？

You're safe from re-infection, 99.9 percent of the time.

99.9%的情况下，你不会再被感染了。

And those nine people make three each one three other people smile.

那九个人 每个人再用笑容感染三个人。

Some may have had undetected mild or asymptomatic reinfections.

有些人或许是未检测出的轻症或无症状再感染。

And people who had just the original two-shot regimen had a similar risk.

打过始两针疫苗的人，再感染风也差不多是 50%。

People with a previous infection reduced their risk of a new infection by about 50 percent.

先前感染者的再感染风至约 50%。

That reduced chances of reinfection by about 80 percent.

这使得再感染的几率了约 80%。

So it's a bit hard to compare the risk of reinfection with different variants.

因此比较不同变异株的再感染风有点难。

Today, we're going to discuss what we really know about BA. 5 reinfection…

今天，我们要讨论对于 BA. 5 再感染的了解。

Are those just stories, or is reinfection really more common now, with the BA. 5 variant running around?

这只是些传言吗，还是随着 BA. 5 再感染现在的确更常见了？

In other words, if you had Omicron in the winter or spring, you're fairly well protected against getting it again now.

换句话说，如果全年冬天或今年春天感染了奥密克戎，现在再感染的几率相当。

Couldn't that also have led to more infections in addition to some feature of the variant itself?

这难道不会也导致更多的感染，再加上变种本身的某些特性？

5 Did an infection that started in his fractured leg—added to the bone disease—cause his death?

5 他的骨折腿开始感染，再加上骨病，是否导致了他的死亡？

Real-world data on reinfection rates will also give a clearer indication on the extent of any change in immunity.

关于再感染率的真实世界数据也将更清楚地表明免疫力变化的程度。

And so these antibodies will stay with us for the rest of our life and so we can't get that.

因此，这些抗体将伴随我们一生，使我们不会再感染那种疾病。

Or if we chop the probability of infection down by another factor of 2, for example meaning people practice better hygiene?

或者如果我们再将感染概率一半，比如人们提高了卫生水平？

Those people had significantly more protection against reinfection with BA. 4 or 5: 76 percent against symptomatic infection, and nearly 80 percent against all infection.

感染过奥密克戎的防止再感染 BA. 4 或 BA. 5 的抵抗力大大增强：对有症状感染的防护率为 76%，而对所有新冠变异感染的防护率接近 80%。

And Assumption Three: after people are infected for a while, they move to the removed group, since they've recovered, or sadly, died, and can't transmit the infection anymore.

在人们被感染一段时间后，他们会转移到转归组，因为他们已经康复了，或者不幸的是，已经死了，不能再传播感染了。

But in general, if you've had COVID or gotten boosted recently, it is safe to say you probably have some protection against reinfection, and especially against severe outcomes.

但总体来看，如果你感染过新冠或最近接种了加强针，可以肯定地说你有一定抵抗力防御再感染，尤其是防御重症。

Yeah, so just, there's studies that follow cohorts of people who are infected for a year, and the reinfection rate is something like somewhere between .

是的，所以有一些研究跟踪了一年内感染人群的队列，再感染率大约在0.3%到1%之间。
