Study: Dramatic decline in effectiveness of All COVID-19 Jabs
As the Delta variant became the dominant strain of coronavirus across the United States, all three COVID-19 vaccines available to Americans lost some of their protective power, with vaccine efficacy among a large group of veterans dropping between 35 and 85 percent, according to a new study.
Researchers who scoured the records of nearly 800,000 U.S. veterans found that in early March, just as the Delta variant was gaining a toehold across American communities, the three vaccines were roughly equal in their ability to prevent infections.
But over the next six months, that changed dramatically.
By the end of September, Moderna’s two-dose COVID-19 vaccine, measured as 89 percent effective in March, was only 58 percent effective.
The effectiveness of shots made by Pfizer and BioNTech vaccine, which also employed two doses, fell from 87 to 45 percent in the same period.
And most strikingly, the protective power of Johnson & Johnson’s single-dose vaccine plunged from 86 to just 13 percent over those six months.
The findings were published Thursday in the journal Science.
The three vaccines held up better in their ability to prevent COVID-19 deaths, but by July — as the Delta variant began to drive a three-month surge of infections and deaths — the shots’ effectiveness on that score also revealed wide gaps.
Among veterans 65 and older who were inoculated with the Moderna vaccine, those who developed a “breakthrough” infection were 76 percent less likely to die of COVID-19 compared with unvaccinated veterans of the same age.
Older veterans who got the Pfizer-BioNTech vaccine and subsequently experienced a breakthrough infection were 70 percent less likely to die than were their unvaccinated peers.
And when older vets who got a single jab of the J&J vaccine suffered a breakthrough infection, they were 52 percent less likely to die than their peers who didn’t get any shots.
For veterans under 65, the Pfizer-BioNTech and Moderna vaccines provided the best protection against a fatal case of COVID-19, at 84 and 82 percent, respectively. When younger veterans inoculated with J&J vaccine suffered a breakthrough infection, they were 73 percent less likely to die of COVID-19 than were their unvaccinated peers.
Johnson & Johnson representatives did not immediately respond to requests to discuss the study’s findings.
The Centers for Disease Control and Prevention has recommended booster shots for everyone who got the Johnson & Johnson vaccine at least two months earlier.
Boosters are also recommended six months after a second dose of the Moderna or Pfizer vaccines for everyone 65 and older; those with medical conditions that make them more vulnerable to a serious case of COVID-19; those who live in nursing homes or other group settings; and those who live or work in high-risk settings like hospitals or prisons.
In addition, all people with compromised immune systems are advised to get a booster shot if it’s been at least 28 days since their vaccine took full effect.
With millions of vaccinated Americans pondering whether they need a boost, the new study offers the most comprehensive comparison yet of how the three vaccines have performed across the nation this year.
It tracked 780,225 veterans of the U.S. armed forces from Feb. 1 to Oct. 1. Close to 500,000 of them had been vaccinated, while just under 300,000 had not.
Hailing from across the country, all were cared for by the Veterans Affairs’ unified system, which provides healthcare to 2.7 percent of the U.S. population. While the group under study was ethnically and racially diverse, the record-keeping that researchers relied upon was uniform.
Because these were veterans, the study population comprised six times as many men as women. And they skewed older: about 48 percent were 65 or older, 29 percent were between 50 and 64, and 24 percent were under 50.
While older veterans were more likely to die than younger vets throughout the study period, the decline of the vaccines’ protection against illness and death was seen in both young and old.
The study was conducted by a team from the Public Health Institute in Oakland, the Veterans Affairs Medical Center in San Francisco, and the University of Texas Health Science Center.
Dr. Barbara Cohn, the study’s lead author, said in addition to its comparison of COVID-19 vaccines, the group’s analysis provides “a lens for making informed decisions around primary vaccination, booster shots, and other multiple layers of protection.” That includes mask mandates, coronavirus testing and other public health measures aimed at countering viral spread.
Strong evidence of the vaccines’ declining power should prompt even states and locales with highly vaccinated populations to consider retaining mask mandates, the authors said. And the findings strongly support the CDC’s recent recommendation that all recipients of the J&J vaccine get a booster.
The study concluded that the Delta variant, which drove a wave of infections and deaths across the country this spring and summer, was likely the factor that most eroded the protection of vaccines.
Other researchers have found similar evidence of declining vaccine effectiveness. But they have suggested that the immune system’s defenses against SARS-CoV-2 simply fade with time, and that waning vaccine effectiveness would likely have been seen with or without the arrival of a new, more transmissible strain.

I keep reading about variants and strains yet no one seems to have identified or isolated the virus that is supposed to be so deadly.

Even stranger is that the same “vaccine” is claimed to be effective against all the new strains. With the flu vaccines they are developed for each strain and the annual vaccination usually has three strains in it. This year it is four.

It is ingenuous to pretend that the viruses of the 2019-20 flu season are still around. Pretending that these not-vaccines confer any protection is a joke because there is no way to expose test subjects to the specific virus being targeted—it has never been properly described and sequenced (outside of a gov’t biolab). So, they assess for an immune response, but that means nothing as they do not have antibodies or proteins from the target virus. Then, they wait for people to get ill.
Meanwhile, it takes time for new viral strains of these flu-type viruses to mutate into strains different enough to not be subject to one’s previously produced antibodies. Thus, the about 6-month waning of the jabs is not real, it’s the schedule of the strain mutation, not the jabs.
As no vaccine or treatment based on one protein of a viral coating can confer protection or immunity, these jabs are by definition not anything close to a vaccine. However, they do set people up for antibody dependent enhancement (ADE) which allows them to become infected more easily, sicker than normal, and die more often, which is exactly what we are seeing on our vaccinated populations.
It is very curious that, as they have been studying the spike protein since 2003 and know it to be quite toxic, they would chose this very protein as the center of these gene-therapy jabs. Better yet, they edited the RNA sequence to make the protein stiffer and also able to break loose into the circulation. This is a bioweapon, not a vaccine by any stretch of the imagination, and which has multiple negative side effects that they are well aware of.

This Coronavirus pandemic is so silly as is the cure to stop anyone from getting a Coronavirus infection, which when left, develops into Covid – like Duh!!
The problem is in the head, it always has been and it always will be, not the body!!
Covid Crusher: Mix one heaped teaspoon of Iodine table or sea salt in a mug of warm water, cup a hand and sniff or snort the entire mugful up your nose, spitting out anything which comes down into your mouth. If sore, then you have a virus, so continue morning noon and night, or more often if you want, until the soreness goes away (2-3 minutes) then blow out your nose and flush away, washing your hands afterwards, until when you do my simple cure, you don’t have any soreness at all, when you flush – job done. Also swallow a couple of mouthfuls of salt water and if you have burning in your lungs, salt killing virus and pneumonia there too.
Gargling, using saline solution or tablets is a waste of time, because they deal with Covid in the body and not the virus in the head, where it is at its most vulnerable – how silly such an easy thing to destroy, is left to become the bio-weapon which kills you.
I have been doing this for over 27 years and not one person has died from this simple cure, or been injured from it from those I have been able to pass it on too, myself included – 100% Effective!!.
The Iodine in the salt kills Coronavirus or the Flu, in the nasal passages of the head and flushes out the escutcheon tubes to the ears, the brain stem and the brain bulb, so no long Covid either – dead Coronavirus = no Covid in the body ever and the salt water provides a protection over the surfaces where Coronavirus and the Flu like to breed – pour a bit of solution on a flat surface and see how it dries – what viruses hate, because it murders them, kills them dead.
Irrespective of if you have been vaccinated or not, do my simple, free cure and avoid further booster shots if you can – or better yet, don’t get vaccinated at all – the vaccines kill, one way or another and horribly too, sooner or later and then we get around to those Nanobots and other things in the vaccines (shudder).
Odd that a long swab up the nose to test for a Coronavirus, is later treated with vaccines in the body for Covid with ARR Efficiency rates of 1·3% for the AstraZeneca–Oxford, 1·2% for the Moderna–NIH, 1·2% for the J&J, 0·93% for the Gamaleya, and 0·84% for the Pfizer–BioNTech vaccines ACCORDING TO The Lancet and Doctors For Covid Ethics and booster shots now lasting for just 2 months, with Covid being at least 98% efficient in killing you?
I have to wonder how effective the shots really are for kids – RRR 90.5% effective means less than ARR on the above efficiency rates?

What will happen after the more unruly elements of society begin to realize that the jab-pushing politicians, business moguls and any others in high position, are responsible for their having been lied to and injected with substances that will bring about a herd-thinning earlier death, greater fear than is normal in their lives, and the anxiety of realizing that they have had their and their future offsprings’ genes permanently altered to usher in misery and death?
