Pfizer vaccine delivering 91 percent immunity for at least six months
https://news.yahoo.com ^ | April 2, 2021 | yahoo

Infectious disease specialist, Dr. Sandra Bliss Nelson, weighs in on finding that show the Pfizer vaccine is performing well;

MIKE SIMPSON: It's holding its effectiveness, basically 90-ish percent, 91%, six months later. So I guess there's two ways to look at it. First is, yeah, six months. That's great. But then another crowd maybe goes, oh, well, maybe it's only six months. Well, it doesn't drop off to 10% the Tuesday after the six-month clock rolls around, right? So it's going to be maybe a sliding scale. We just have to see how far it goes.

SANDRA BLISS NELSON: I think that there's a couple of points to this. I mean, the first is that there's really no opportunity to know more than about six months. We really have only had these vaccines in clinical trials for that duration of time, so it's not to say exactly as you pointed out, that there's going to be a cliff at the end of six months. It's really just that that's as far as we really know.

But we have begun to learn more about immunity after natural infection, and we believe that that immunity lasts at least six months, if not a little bit longer. And given that vaccination seems to produce more potent immunity than natural affection itself, there's really no reason to think that we're going to get more durability out of this vaccine than six months.

CDC investigate every death reported after a vaccination and they've found not a one that was caused by the shots.

If you honestly believe those numbers, you are the second most credulous person on FreeRepublic

I see you provided argument as to what I said.

Israel has demonstrated arrest of transmission of disease and prevention of disease

CDC even has had to admit the same

Simply because YOU want people to not get vaccinated for whatever narcissistic reason of power and control is on you. I have merely provided actual data refuting your ridiculous talking points.

Clearly you need the education

I've been exposed to Covid four times. I tested ''positive asymptomatic'' a year ago and had to stay home for a week. I work in a hospital ER. I'm around the filthy thing all day. As I said, I'm still on two feet and breathing.

insult. No. These vaccine where not approved. Meaning they're not backed by any kind of science.
based on the studies I given above mRNA vaccines will have a high probability of epitope. Antibodie bonding can be something like HIV.20. Where your immunity system can't function.

FRiend, I work in a hospital ER. Last year my employer told me that I had been exposed to Covid four times. I tested ‘’positive asymptomatic’’ and had to stay home for week.

I work around the filthy thing all day. I’m 64, have a pace maker, high blood pressure and an anxiety condition.

Back in January some a$$hole attacked me in the hospital parking lot(a road rage incident, goes to court next week).
Life is never dull for me.

But, I’m still on two feet and breathing, thank God. Could be worse.

To disbelieve them you have to assume both the FDA and CDC are engaged in a conspiracy to deceive us. And this conspiracy has to be massive because there are probably thousands of people in those agencies involved in tracking and investigating adverse events.

Before other sources come to light please let us know which other agencies/organizations are in on this conspiracy. Or is it safe to assume that any data that doesn't fit with your world view must be the product of a conspiracy?

mRNA is not the same as DNA, and it cannot combine with our DNA to change our genetic code. Once inside the cell, the mRNA comes into contact with protein making-machinery located in the jelly-like cytoplasm filling the cell.

mRNA does not enter the nucleus, which is where our chromosomes (DNA) are stored. It is also relatively fragile, and will only hang around inside a cell for about 72 hours, before being degraded.

mRNA vaccines are based on the same processes going on in our cells now and since the dawn of RNA: — delivering mRNA into our cells, which they will use to manufacture a viral protein.

For instance, when we are infected with a virus - including relatively harmless viruses like those that cause the common cold - these invaders inject their genetic material into our cells, resulting in pieces of mRNA encoding viral proteins for the common cold being sent to our protein-making machinery.

The mRNA vaccines for COVID-19 work the same way as the common cold virus.

The mRNA Covid 19 vaccines provide instructions for making the same viral Covid-19 protein -— the coronavirus ‘spike’ protein used by the virus to gain entry to our cells.

Studies indicated that it was highly immunogenic, meaning if our immune cells encounter this protein, they will mount a strong response -— which should protect recipients against future COVID-19 disease.

Once our cells have manufactured the viral protein, it is displayed on their surfaces where passing immune cells can spot it and respond.

And, again: the mRNA either through a vaccine or through a virus itself (like the common cold) does not enter the nucleus, which is where our chromosomes (DNA) are stored. It cannot combine with or alter our DNA in any way.

No, because everyone is advised to not get their flu shot too early in the year so they are still immune by the spring and the end of flu season.

quibble much?

Researchers are now picking apart the available data, looking for signs that T cells could help to maintain lasting immunity.

“We know the antibodies are likely less effective, but maybe the T cells can save us,” says Daina Graybosch, a biotechnology analyst at investment bank SVB Leerink in New York City. “It makes sense biologically. We don’t have the data, but we can hope.”

Coronavirus vaccine development has largely focused on antibodies, and for good reason, says immunologist Alessandro Sette at the La Jolla Institute for Immunology in California. Antibodies — particularly those that bind to crucial viral proteins and block infection — can hold the key to ‘sterilizing immunity’, which not only reduces the severity of an illness, but prevents infection altogether.

That level of protection is considered the gold standard, but typically it requires large numbers of antibodies, says Sette. “That is great if that can be achieved, but it’s not necessarily always the case,” he says.

T cells do not prevent infection, because they kick into action only after a virus has infiltrated the body. But they are important for clearing an infection that has already started. In the case of COVID-19, killer T cells could mean the difference between a mild infection and a severe one that requires hospital treatment, says Annika Karlsson, an immunologist at the Karolinska Institute in Stockholm. “If they are able to kill the virus-infected cells before they spread from the upper respiratory tract, it will influence how sick you feel,” she says.

Life Span of Memory T Cells: From studies in mice, the life span (period of interphase) of T cells in thoracic duct lymph was calculated to be approximately 4 to 6 months (493), a period that is remarkably similar to the estimated half-lives of CD4+ and CD8+ T cells in human peripheral blood.

To repeat the analyst: “We don’t have the data, but we can hope.”

It’s not a conspiracy when they tell you they’re lying to you and you believe it anyhow.

Occasionally I will visit these threads and immediately regret it.

Yes, these threads have a significant signal to noise ratio.

I don’t know what the big deal is. There’s enough information out there for each person to make a data informed decision.

But at the end of the day, it is each person’s decision. And FReepers need to accept that - and move on.

Some of the worst offending issues are 1) mask wearing and 2) vaccines. Good grief, people. Don’t get so wrapped around the axle that others don’t see COVID-19 issues the same as you or make the same decision as you. Provide references for your positions and argue as politely as possible. That’s all you can do.

Re: 131 - Why does it trigger you so that FReepers don’t believe the same way you do regarding COVID-19 issues?

You continue to lie. Not only about the microbiology,
but also about what is known about the virus (manufactured
by the very same people who made the "vaccine"
designed BEFORE the release of the criminal BIOWEAPON)
and also in your reprehensible BS about what I "want".
You are a liar. I want people to be educated for
informed consent - which you and BIG Pharma
and your pedophiles DO NOT WANT.

LOL!!!

I’m not offended - just asking why you get triggered apparently so easily when people don’t agree with you.

I don’t believe that all, more like 19%.

Sounds like you might have heard. The FDA and CDC investigate every death reported after a vaccination and they’ve found not a one that was caused by the shots.
**************

Of course they wouldn’t find anything. They are sooo trustworthy. I have read plenty of first-hand accounts that say otherwise.
