Behind the Masks, a Mystery: How Often Do the Vaccinated Spread the Virus?

The recommendation that vaccinated people in some parts of the country dust off their masks was based largely on one troublesome finding, according to Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention.

****New research showed that vaccinated people infected with the Delta variant carry tremendous amounts of the virus in the nose and throat, she said in an email responding to questions from The New York Times.

The finding contradicts what scientists had observed in vaccinated people infected with previous versions of the virus, who mostly seemed incapable of infecting others.

That conclusion dealt Americans a heavy blow: People with so-called breakthrough infections — cases that occur despite full vaccination — of the Delta variant may be just as contagious as unvaccinated people, even if they have no symptoms.

Problem is, we have to get *ahead* of an ever changing virus.

Which means, apply the precautionary principle -- assume it's going to be worse than you know, and plan for that.

Stuff like:

* Continue to wear masks. (is this not the easiest recommendation ever, or what?)

* Start with the boosters *before* you discover the next variant has arrived that needs a booster. Pfizer already has a study done, has applied, and waits for somebody's approval. Someone should be accelerating this process as fast as possible.

Why would the booster be anymore effective than the two shots? Really, truly. The efficacy is near 40% maybe 19% in the Israel's studies. Will the Booster go back to 40% every six months and drop back to 19% or worse in two months afterwards.

There are treatments for Cancer right? Maybe we need to look at treatments over the current non-effective strategy for COVID. Just saying.

Jul 2021

Thus the name.

And, note I mentioned we need to be thinking about the *next*, more virulent variant, not the one we know about now.

But, back to Delta, if you get a booster then you have an immune system more at the ready to start fighting it when you get your viral load intake, you'll do better (faster) at killing off the viral infection.

From the NY Post (Yeah I know, but nonetheless):


The pharmaceutical company released data that showed that the booster shot could increase antibody levels against the mutation by more than five-fold in people ages 18 to 55, compared to just two doses.

For those ages 65 to 85, the third dose boosted antibody levels more than 11-fold.


Which means two things:

1) The seriousness of your symptoms go down
2) Since you're more likely to kill off the virus before it can replicate to levels where you can re-transmit it, reinfection levels drop even from vaccinated individuals.

It's kinda like the positivity rate that everyone was looking at when the pandemic first started. I quickly started to look at raw number of cases because the positivity rate was based on availability of tests.

Since Israel has a vaccination rate of 85%, a good portion of those who are positive are vaccinated. Their actual numbers of cases are not alarming. They are concerning, but not 1/2 as bad as it seems.


I made a post about it earlier today.

Since we used the same vaccine as Israel, and Israel is starting a boosting program, clearly we need boosters-there is no way we don't. And yet we are being told we don't.

The article states just this. Read it. And there is still infection found after fully vaccination in the nose and mouth of vaccinated individuals. This is what the article says which is quote from the CDC itself.

Thu Jul 29, 2021, 08:25 PM

Serious hospitalization and death are rare, even with Delta if you have been fully vaxxed. That is the first and most important goal for a vaccine.

But:

Semi-serious consequences can still happen (and I don't know the numbers on that, but assume it will be at a higher rate than hospitalization/death.
Vaccinated individuals can re-transmit the virus.

We need to make it so that when the virus hits a vaccinated individual, it doesn't have a chance to replicate to prevent those two things.

That's not what vaccines do. Vaccines don't fight the virus. They cause the body to make antibodies that fight the virus at a cellular level. It's not a shield.

The shield is a mask! It couldn't be simpler. And we can't even get some people to wear them. And some of them get angry if we wear them!

And yes, if you read this whole thread you'd see I clearly know that vaccines cause antibody production.

But the entire game is about not getting a viral load which becomes an "raging" infection before the immune system can stomp it out.

Masks, vaccines, social distancing are all "tools" in the tool kit that can help with that.

Eventually if we can deprive this virus of hosts, it will disappear. That's not going to happen now, because it's a global problem. So we're likely going down the make better and better vaccines path.

a couple of days ago saying they and their partner had just received their trial booster shot. Sorry, can’t find it to link.

So, yes, Moderna will probably require a booster, too.

What I haven’t found is whether or not Pfizer and Moderna have used their technology to change the mRNA in the booster to be specific to the delta variant. Would they have to start whole new trials from just changing the mRNA spike protein, or is that what this booster trial is about?

A third dose of the same exact vaccine or a variant specific booster increase antibody levels, which is what you need to fight delta.

I misremembered, it was a booster trial for Pfizer, not Moderna. Someone who was in the Moderna trial posted a comment down thread and confused my poor old brain.

I understand that more antibodies circulating would offer more protection, but I also understood that one or two of the delta variant mutations is to the spike protein allowing the virus to more efficiently attach to and invade cells. Thought/hoped that a variant specific booster might fight the virus more efficiently, maybe even prevent transmission from the breakthrough cases.

It’s difficult but I guess we’ll have to be patient and wait for results. Hub and I got our second jab in early March. We’re almost at the six month mark.

since they change every year. Looks like they don't do Phase II or III trials each year but do some lab tests. They rely on VAERS (reporting system).

https://www.fda.gov/consumers/consumer-updates/fdas-critical-role-ensuring-supply-influenza-vaccine

I believe there is a danger if you change the mRNA because there might be an immune system reaction to a new protein/peptide?

Since the current vaccines work pretty/ fairly well, that seems like the safer course to me.
