We're allowing hundreds of thousands to pour over the Southern Border from South America, where the Lambda variant is dominant. Keep that in mind when you read the rest of this.
The title of this new paper speaks for itself: "SARS-CoV-2 Lambda variant exhibits higher infectivity and immune resistance"
Notable here, is the case of Chile, where the vaccination rate is relatively high. The percentage who received at least one dose of COVID-19 vaccine was ~60% on June 1, 2021."
However, the new study focuses on vaccination, not natural immunity, and how the Lambda variant is so "proficient in escaping from the antiviral immunity elicited by vaccination."
The same is also true of the Delta variant.
Researchers prepared the viruses pseudotyped with the S proteins of the Lambda variant as well as four variants of concerns (VOCs), Alpha (B.1.1.7), Beta (B.1.351), Gamma (P.1) and Delta (B.1.617.2). The infectivities of the Alpha and Beta variants were significantly lower, as were the infectivities of Gamma.
However, Delta and Lambda variants were significantly higher, as was Epsilon (though that variant is believed to be stamped out). What they found suggests the more infectious the variant, the more resistance it is to vaccine immunity.
IMPORTANT TO UNDERSTAND: Research from Piccoli in 2020 found the receptor binding domain (RBD) of the SARS-CoV-2 S protein is immunodominant, and mutations in this domain can lead to immune evasion. Research from McCallum in 2021 found the mutations in the N-terminal domain (NTD) of the SARS-CoV-2 S protein are associated with the escape neutralization.
These results suggest that the Lambda S is highly infectious and resistant to the vaccine-induced humoral immunity, and the robust resistance of the Lambda S to the vaccine-induced neutralization is determined by a large deletion in the NTD.
What about that large deletion referenced?
Virology experiments found that a large 7-amino-acid deletion, the RSYLTPGD246-253N mutation, does not affect viral infectivity. However, it is responsible for the resistance to the vaccine-induced neutralization as well as an NTD-targeting NAb.
Bottom line: This, and all the other research suggests that Alpha is the key to surviving a longterm pandemic like this. You must be exposed to, and survive, Alpha. Exposure to the parental strain provides significantly higher immunity, significantly less symptomatic response, and fewer rates of hospitalizations. I'd like to see similar studies comparing immunity with Lambda like we've seen previously from Delta and others.
"These observations suggest that acquiring at least two virological features, increased viral infectivity and evasion from antiviral (vaccine) immunity, is pivotal to the efficient spread and transmission in the human population."
We're being outsmarted by a virus, folks. I imagine that's because it doesn't consult it's ideology before it decides how to react. We're going to discuss this more in a live stream today, shortly.

During Road Rage I mentioned that a nasty storm was brewing, and figured I'd show you.
Ha!
Sorry, folks.
I put it as an image before and not a video.
The GOP donor class doesn't at all share the values of the GOP base, and when they win elections, the donor class wants payback and the base wants promises kept.
The donor class wins every single time.

Welp, I'm back. After we got done earlier and we spoke with Ro, Laura tried to no avail taking a nap, but was constantly bothered by one of the children. Lol.
But then I spoke with my father for a good long while, which was nice. Joe Piscopo called and sent him a recorded video after, which was super nice of him. My father would've loved watching that performance.
Tomorrow, I'm think we may be starting at 6:30pm so I can do a quick update with Matt Gaetz on his show. If not WATO, I'll try just doing ITN solo.
Good to be home, as usual, where we'll stay for a few days before heading to Chattanooga for the event with Barnes!
Watching people attempt to "unskew" polls conducted by all walks of this industry—ranging from Nate Cohn at The New York Times to Spencer Kimball at Emerson College to Tim Malloy at Quinnipiac—all to deny Donald Trump's gains against Joe Biden with various voting blocs, is more than a little sad.
The slew of recent polls over two weeks—to include no less than four today alone—have simply confirmed prior findings published from other pollsters who have previously been "unskewed". That includes your's truly and our work at BIG DATA POLL, Mark Penn at Harvard University, Patrick Ruffini at Echelon Insights, and many others.
I'm temped to equate this with an Occam's razor-like situation. But this debate is more about likelihood than simplicity.
Here's the Presidential Vote Preference Trend for Biden v. Trump going back to August 2020. The Public Polling Project did not begin asking the Rematch Question for 2024 until September 2021. However, we can still make some pretty important and interesting observations.
