Individuals who are double-vaccinated or recovered from COVID-19 have “virtually no protection” against the Omicron variant, according to a peer-reviewed study.
The research, led by Rudolf Valenta of the Medical University of Vienna, found that only people who had received the third dose of a COVID-19 vaccine can form antibodies that could partially block Omicron, although noting that the protection is far from optimal.
“The third vaccination developed protective antibodies in many individuals,” Valenta said, adding that “there is also a significant proportion (20 percent) in whom no protection was established.”
According to results of the study recently published in the journal Allergy, researchers with the Medical University of Vienna examined an Austrian subpopulation of people who had been vaccinated or recovered from the CCP (Chinese Communist Party) virus. Scientists examined individuals’ antibody status and protection against the Wuhan, Delta, and Omicron variants, strains that are currently prevalent in the European country.
The study involved people who received all types of COVID-19 vaccines and vaccine combinations currently licensed in Austria.
Regarding the Omicron variant, researchers developed a test for the previous variants that investigates whether the COVID-19 strain can bind to the receptor on human cells via its receptor-binding domain (RBD).
“The results showed that both COVID-19 convalescent individuals and individuals who had been vaccinated twice had developed antibody protection against Delta. However, the antibodies were not able to block receptor binding against Omicron,” the researchers found.
An RBD is a key part used by a virus, including the CCP virus, to enter the “spike protein” domain that allows viruses to dock to the human body, gain entry into cells, and lead to infection.
The RBD differed only slightly in all CCP virus variants previously known, researchers said, adding that the COVID-19 vaccines that are currently available could provide protection against infections caused by these previous strains.
“Omicron is the first variant that differs greatly from the previous variants in RBD, consequently, infections with the previous variants and currently available vaccines provide little or no protection against Omicron,” the study found.
The researchers noted that the best protection would be to develop a broadly effective combination vaccine that could protect against both the previous CCP virus variants and Omicron.
“Until we have such a vaccine, only repeated vaccinations with the existing vaccines will provide some protection,” Valenta said. “The protective effect achieved by vaccination can be evaluated with special tests that can be rapidly adapted to new virus variants.”
Omicron became dominant in the United States in December 2021 and other studies have already suggested it can evade protection from COVID-19 vaccines and prior infection better than Delta. Most previous studies have also found that natural immunity remains superior to vaccination, including while Delta was dominant.
In a recent study, antibody protection against the CCP virus among recovered individuals was detected at 20 months post-infection, adding to the body of evidence that such protection, known as natural immunity, is long-lasting.

Will America-First News Outlets Make it to 2023?
Things are looking grim for conservative and populist news sites.
There’s something happening behind the scenes at several popular conservative news outlets. 2021 was bad, but 2022 is proving to be disastrous for news sites that aren’t “playing ball” with the corporate media narrative. It’s being said that advertisers are cracking down, forcing some of the biggest ad networks like Google and Yahoo to pull their inventory from conservative outlets. This has had two major effects. First, it has cooled most conservative outlets from discussing “taboo” topics like Pandemic Panic Theater, voter fraud, or The Great Reset. Second, it has isolated those ad networks that aren’t playing ball.
Certain topics are anathema for most ad networks. Speaking out against vaccines or vaccine mandates is a certain path to being demonetized. Highlighting voter fraud in the 2020 and future elections is another instant advertising death penalty. Throw in truthful stories about climate change hysteria, Critical Race Theory, and the border crisis and it’s easy to understand how difficult it is for America-First news outlets to spread the facts, share conservative opinions, and still pay the bills.
Without naming names, I have been told of several news outlets who have been forced to either consolidate with larger organizations or who have backed down on covering certain topics out of fear of being “canceled” by the ad networks. I get it. This is a business for many of us and it’s not very profitable. Those of us who do this for a living are often barely squeaking by, so loss of additional revenue can often mean being forced to make cuts. That means not being able to cover the topics properly. Its a Catch-22: Tell the truth and lose the money necessary to keep telling the truth, or avoid the truth and make enough money to survive. Those who have chosen survival simply aren’t able to spread the truth properly.
We will never avoid the truth. The Lord will provide if it is His will. Our job is simply to share the facts, spread the Gospel, and educate as many Americans as possible while exposing the forces of evil.
To those who have the means, we ask that you please donate. We have options available now, but there is no telling when those options will cancel us. We just launched a new GiveSendGo page. We also have our GivingFuel page. There have been many who have been canceled by PayPal, but for now it’s still an option. Your generosity is what keeps these sites running and allows us to get the truth to the masses. We’ve had great success in growing but we know we can do more with your assistance.
Thank you, and God Bless!

New studies of effectiveness of Ivermectin emerging every day. Peer-reviewed, large PSM study from Brazil finds, regular use of ivermectin as a prophylactic agent was associated with significantly reduced COVID-19 infection, hospitalization, and mortality rates. The study was published in the Cureus Journal of Medical Science. This medicine is proven over and over again to be effective for covid and flu like symptoms.
