Against the Delta variety.
If confirmed, they will not get full approval. Moderna fixing to eat.

Jack Posobiec gives no context, of course. So I dug up the actual study. Here is what it says:
In other words, Moderna still going strong at 76%. Pfizer seems to be down to 42% against Delta insofar as protecting against infection.
However, they also said this:
As you can see above, Moderna was 91% effective at preventing hospitalization and Pfizer was at 85%. So let's not pretend it's the end of the world. Yes, the efficacy has decreased with Delta, but the beauty of mRNA is they can quickly tweak it for new variants (in like days). They don't have to grow or culture the virus to do this.

Both vaccines were highly effective during this study period against SARS-CoV-2 infection (mRNA-1273: 86%, 95%CI: 81-90.6%; BNT162b2: 76%, 95%CI: 69-81%) and COVID-19 associated hospitalization (mRNA-1273: 91.6%, 95% CI: 81-97%; BNT162b2: 85%, 95% CI:73-93%). However, in July, the effectiveness against infection was considerably lower for mRNA-1273 (76%, 95% CI: 58-87%) with an even more pronounced reduction in effectiveness for BNT162b2 (42%, 95% CI: 13-62%).

Our observational study highlights that while both mRNA COVID-19 vaccines strongly protect against infection and severe disease, further evaluation of mechanisms underlying differences in their effectiveness such as dosing regimens and vaccine composition are warranted.

How do they compare to natural immunity?

Does that mean the vax passports are no longer valid for Pfizer jabs?

Don’t care. I am not vaccinated. I feel fine.

Pfizer bux in the right hands= Breaking News--new standard for vaccine efficacy for Covid now at 42%

Curious how they determine if it is the vax that is effective at prevetnting hospitalization.

So boosters for life. Beauty is in the eye of the holder I suppose.
Tell me more about natural immunity. That is, IF you can actually find any info that isn’t either dismissed (like Dr. Catherine O’Neal did as JBE’s mouthpiece), limited in scope, or....seemingly buried.

If you had a non Delta variant infection they're effectively the same.

The relative risk reduction is what they are reporting and that doesn’t have any real world impact when the actual risk is through the floor in the first place.

Based on what? Links?
ETA
There is zip about natural immunity being in the 42% to 87% range concerning the Delta variant. There are studies that show it works at a higher percentage (90%+), but nothing in the range that you suggested (“effectively the same”).

Where is he getting the 42% efficacy claim? I’m not saying he’s wrong, but he doesn’t site any studies but simply makes a claim.

So a new shot for each “variant”?

Here's a summary of what we know about naturally acquired immunity:

Cliffnotes... durability of immunity conferred by prior infection is variable, and less protective against delta variant (especially if prior infection was more than 6 months ago.) Also, vaccinated after infection are half as likely to be reinfected (see the Kentucky study.)

What is hospitalization % of unvaccinated ?

Is that the game plan? Asking people to get jabbed for each variant?
If people oppose getting one or two to talk it’s going to get ugly if it’s multiple per year.

The Kentucky study was bullshite.
How can you push this drivel and act like you have any semblance of credibility.
The dumb bitch writing your article is citing a study with FIVE people.
frick off with this garbage.
Here is the CDC link to that “study.”
