Well, as they say, winter is coming, and there are growing concerns from health experts about a group of Omicron subvariants.
Yeah, these new strains are able to dodge our immune defenses, and they pose a new threat to both vaccinated and previously infected people.
Here to help us break that all down, NBC News medical fellow Dr. Akshay Syal joins us. Thank you for being here in studio with us.
So let's talk about these new variants, they're a derivative of the Omicron strain. What is it about these Omicron spin-offs, if you want to call them, that we should be concerned about? What should we be worried about?
So, good afternoon, it's good to be here with you, and what these experts are describing to us is this is a viral evolution on steroids.
We're seeing a bunch of little spin-offs of Omicron. There's a couple concerns here, the first is we're going to see another rise in cases as we head into the fall and winter season.
The other thing we're watching for is, is those tools that we have in our toolbox will they still be effective? I spoke to Dr. Fauci about this and here's what he had to say.
If BA.4.6 evades and you shelled and that's another tool in our armamentarium that will not be usable for people who are immune compromised.
And so what he was referring to is Evusheld⁽¹⁾, it's a monoclonal antibody that if you have a weak immune system, you actually get as an injection to prevent you from getting sick.
And the concern is that may not work with these spin-offs. - So that's in addition to the vaccination? - If you have a weakened immune system.
令人担忧的是，这Evusheld可能对这些奥密克戎亚变体不起作用。 - 那这是在疫苗接种之外用的药吗？ - 如果你的免疫系统较弱（则建议注射）。
First off, great interview with Dr. Fauci. Thank you for bringing us that information, but also, I mean, just make the booster shots worth it then, I mean is it something that can even help us against this new variant?
It's an excellent question, you know, we're not seeing the demand for the booster that high.
So I asked Dr. Fauci, you know how, what do I tell my patients? why should they get this booster if those BA4 BA5 variants are no longer the dominant variants?
And he said cross protection, all that means is these new boosters we have are closer related to these spin-offs and the old vaccines. So if it's a good idea, especially if you didn't have an Omicron infection.
Let's say you got sick. should you still wait to get that booster? and what should people who are immune compromised, what should they know?
if you're immune compromised, I wouldn't wait. If you recovered from an infection, I would get it as soon as you able to, but... - Don't wait for three months, like I used to say.
如果免疫系统受损，我会毫不犹豫（注射加强针）。如果从感染中恢复过来，我也会尽快注射加强针，但是… - 不要像我以前说的那样等三个月。
I wouldn't, but if you're not immune, compromised, you really want to wait three to six months to get the most bang for your buck from that booster?
Which I have to say it sort of begs the question, is this sort of fly in the face of this herd immunity that we all thought was going to be just a silver bullet⁽²⁾ to get us out of this pandemic once and for all.
我不得不说，它回避了一个问题，这是对群体免疫的一种挑战，我们都以为群体免疫是记一良策，能让我们一劳永逸地摆脱这场大流行。⁽²⁾silver bullet，指能解决大麻烦的简单方法、最强杀招、良方、妙招、灵丹妙药。在西方古代传说中被银子弹认为是狼人和吸血鬼的克星, 是杀死狼人的唯一方法。
You know, a little bit, I will say, all the experts I've talked to say this virus isn't going anywhere. We need to learn to live with it this winter, probably the next winter, too.
So, let's take advantage of those tools that we have. - It's starting to feel like the flu all over again. - All right NBC News medical fellow Dr. Akshay Syal thank you so much. - Anytime.
所以，让我们充分利用这些“工具”。 - 感觉好像流感又发作了。 - NBC新闻频道的医学研究员阿克谢·赛尔博士非常感谢你。 - 随时为您效劳。
