A new, rapidly spreading variant of SARS-CoV-2, the virus that causes COVID, means a rise in new infections could be around the corner. And while it likely won’t skirt immunity completely, the variant could dodge some of our defenses thanks to a mutational boost.
Crucially, despite being a few dozen mutations away from the subvariant BA.5, which dominated last summer, XBB.1.5 is still a form of Omicron and not some completely new SARS-CoV-2 variant. It is also very similar to its parent lineage, XBB—itself a combination of two lineages descended from the subvariant BA.2 that dominated last spring.
The mechanism behind XBB.1.5’s increased transmissibility isn’t known for sure. But the subvariant’s F486P mutation allows the virus to more effectively latch onto ACE2 receptors in the body—“the doorway through which the virus gets into cells in our noses, throats and lungs,” Young says. “There has been significant confusion in the narrative of protection,” Sette says. “It’s relatively easy for a virus to mutate to escape antibodies because they are limited to a certain area of the virus’s spike protein. But what about cellular immunity? The mechanism by which T cells recognize the virus is completely different.
so is natural immunity
Somebody needs to be figuring out how to kill this damn thing. Whoever unleashed this freaking plague on the Earth should have to suffer from it just like the rest of us.
Imagine believing this…
There’s a vaccine for Covid ? Wow when did that happen ? Won’t take the clot shot , I’m not Jesus Christ and it’s not my job to take the Vaxx to save everyone else .
Covid vaccines kill
Jabwashing
scientific(ly), absolutely no proof whatsoever. rico/nuremberg2.0
What is unscientific saying today?
Show us evidence of this. You are Scientific American not Pfizer's marketing department.
Please more good news. We are saturated with bad news.. like saturated fats, bad news saturation is a health risk.
' likely' sounds like big pharma propaganda. They know it doesn't work but take it anyway because the new world order needs its profits and the world population is to high. We are taking bets at work to see what athlete drops dead mid game from the vax.
If nothing else the experimental, untested, deadly vaccines will kill you before the COVID gets you… Winning!!!
How much is the govt paying you to put this bs out?
I feel like for a twitter account called scientific America you would be up in arms about the origin of covid 19 and also trying to protect the people with data relating to the 'vaccines' and the development of real vaccines that actually stop the virus from spreading. But nope.
Governments around the world fucked this up with incompetence and greed. It's either that or covid 19 was developed for reasons to do with population control and or a money making scheme.
Covid 19 has no vaccine, Pfizer and all these other companies have made therapeutics not vaccines. Why are you using verbiage that's misleading? The definition of vaccine means you won't catch the disease. They definition was changed so that these big pharma companies can make $
Leftists have told how many lies about how wonderful those vaccines are?
So you’re saying the vaccines are a sham good for you for speaking the truth
🙄🙄🙄🙄🙄
lmao
'Likely'. Cmon, likely? Nobody knows do they, like when the CDC told us that if you're vaccinated, you won't get covid or transmit it to another person, which was bullshit. Just like your post.
Now that you mention 'vaccine' you immediately lose all credibility.
Because the vaccine has really weakened your natural immune system and now your body is all fucked up. Disclaimer as to not lose my account for the 6th time: All just speculation on my part
I'm vaccinated against measles and other childhood illnesses. Because of that, I never got those illnesses. I'm vaccinated against covid, yet still got covid. And it was scary because I had a hard time breathing. I almost had to go to the emergency room.
You keep saying this word, vaccine. I don’t think it means what you think it means.
Just in:
If you take the vaccine you can expect to get sick with covid. I never took the vaccine and I never had covid. Funny how that works.
No.
I've had all the shots but caught Covid on film set in UK. To me, it was just a stuffy cold and was gone in a week. Trust the science. It works.
I disagree... so do the studies.
What vaccine?
There is no research to back up this claim. Lots of evidence, however, that shows no efficacy at all in preventing infection.
If I die I die.
Vax doesn't prevent anything except a healthy heart. Stop lying!
'vaccines are still likely to protect'? I'm likely to get HIV from unprotected sex with a crack whore. That's 'still' not a good reason to do it.
Sure... I'm so terrified... I just feel sooo threatened. I'm done with that sh...
This never ending nightmare has to stop. For those that wish, please consider signing and amplifying our petition to congress urging them to fund next gen vaccines. We need something better - this is not sustainable.
Ohhhhh it has a scary name ohhhh so scary. Better ruin everyone's lives and destroy the world economy again because of scary scary name bug that doesn't really do much when you get it except make you a bit sniffy.
'Scientific™' American
I will stick with my immune system. This poker player acquired 19 after playing poker at the Commerce Casino Jan 15th 2020 or so. Had bad lung ailment til Feb 9th, 2020. Then caught Omnicom while playing poker at the Hard Rock late July early Aug 2021. I survived!!
Cut the Crap !
To all the anti-vaxxers-You do know that SARS-CoV-2 'jabs' your insides with it's spike protein PLUS THE RNA Viral GENOME that hijacks your cells to become production factories for more viruses,right? Your cells then produce MORE spike protein PLUS all other parts of the virus!
Fingers crossed this variant continues the trend of making COVID more mild and less likely to lead to long haul symptoms.
Brought to you by Pfizer.
They act like Drug pushers, Take this for a better dream world. More app to die in the future that's the reality of your virus protection. Big farmer companies sound more and more like cartels everyday, bummer
The vaccines that make you MORE LIKELY TO GET THE DISEASE? I suppose if you want to die a sudden death and be more likely to get the disease you could take the experimental vaccine. I’ll pass.
You guys are a joke.
How much did Big Pharma pay you to worry that?
Once you realize that's a living thing you certainly don't want it setting up housekeeping in your lungs. Masks protect others from your exhaled droplets. Be a sweetheart and wear a mask the life you save could be someone you love or even your own.
CrednesCodPeace Serious question. Are they modding the vaccines to cope with mutations, or any plans to?
Get your vaccine updates when recommended! Repeat COVID infections will take a toll.
Wish you people would stop making stuff up and scaring every one.
Nobody cares
‘The vaccines, which we all know don’t prevent transmission, and are potentially the cause of the new variants themselves, are still the best protection against transmission you have’ 🥴 Honestly, who is still listening to this Big Pharma bollocks?
Here we go again.
