The Pfizer/BioNTech and Moderna vaccines carry instructions to produce a variant of the spike protein that has been locked into whats called a prefusion-stabilized conformation. Ivermectin, hydroxychloroquine, and chloroquine are especially important in preventing new binding of the spike protein to the ACE2 receptors that need to be bound in order for either the spike protein alone or for the entire virus to gain entry into the target cells ( Lehrer and Rheinstein, 2020; Wang et al., 2020; Eweas et al., 2021). The miscegenation seems to be the common factor for the number of new variants from South Africa, Brazil, United Kingdom and the United States. Spikes proteins can not be floating around after being made and transit to other AC2 receptors elsewhere in the body. The cells present the spike protein on the surface. Email sent to FactCheck.org. extended to treat other RNA viruses in the future. , a member of the faculty at Harvard Medical School and of Harvards Wyss Institute for Biologically Inspired Engineering, who co-authored a study that found circulating SARS-CoV-2 vaccine antigen in the plasma of vaccine recipients. .

See: https://www.jpost.com/health-science/could-an-mrna-vaccine-be-dangerous-in-the-long-term-649253, If these spike proteins are expressed in endothelial cells, which are found in the vascular system, brain and other organs, the protein can presumably damage that tissue in a way that may not be readily apparent. (See our Email Privacy Policy for details.) This is how they escape without being torn to pieces. Updated 21 June 2021. Walt, a pathology professor, added there is no evidence that the spike protein is a pathogenic protein that causes damage in several tissues. These efforts range from understanding the structure of the virus to mobilizing the bodys immune reaction. development of COVID-19. . Statement, Canadian Paediatric Society. Covid makes most people not ill at all or a little ill as well. 21 . All nice, but the spike proteins are already IN the cells since they are produced there and the study says: [] but this is the first study to show that the damage occurs when CELLS are exposed to the spike protein on its own. Ogata, Alana, et al.Circulating SARS-CoV-2 Vaccine Antigen Detected in the Plasma of mRNA-1273 Vaccine Recipients. Clinical Infectious Diseases. Were on the receiving end of a very incomplete picture from mainstream media because they dont want to encourage vaccine hesitancy. So the spike proteins dont need to exit the cells and they dont need to bind to new cells. (Salk Institute) Usually, a person's immune system turns on when it's needed, slays an infection, then turns off. proteins and the development of COVID-19. Bridles interview was reposted by several publications, including one owned by Robert F. Kennedy Jr.s anti-vaccination organization. 23 June 2021. Kelly, Jeannie, et al. Structural biologist at the University of Texas at Austin. Accessed 29 June 2021. . FACT: The COVID-19 vaccine will not affect fertility. Because it is stopped once made, because the cell recognizes is as foreign protein and send it off for destruction, and hands its smashed parts from the endoplasmic reticulum (ER) to the MCH mechanism which hands it off to the T-Cell immune system for removal. My statement that the spike protein migrates to the surface of the cell so as to be recognized by the immune system is not a very accurate simplification. Heres a step-by-step guide to how they work. , or VAERS, which is an early warning system run by the Centers for Disease Control and Prevention and FDA. Your beta cells in your immune system know better than to copy random mrna in the body. In this review, we have initially performed a meta-analysis of keywords associated with the S protein to frame the outline of important research findings and directions related to it. 2 today, but of SARS-CoV-3 tomorrow.

Press release, Government of Canada, Health Canada. The point of the mRNA vaccines that you dont *need* the virus itself there to replicate because the mRNA is there to be read and the spike protein is produced. The mrna enters a cell (also in the brain, thanks to the lipid hull). According to the Centers for Disease Control and Prevention, the most intensive safety monitoring in U.S. history has found that most of the reported side effects after COVID-19 vaccination are minor, such as pain at the injection site or fever. Like. For more, see How safe are the vaccines?. COVID-19 Vaccine Research at U of G Awarded Provincial Funding. The one Dr. Malone particularly pushed is from Salk Institute, where researchers injected SARS-CoV-2 spike proteins into hamsters, which injured the lungs and blood vessels due to angiotensin . inhibitory factor) plays a role in pancreatic cancer. The new technology treatments give mRNA to teach your own cells to make the spike proteins. However, it says, based on available data COVID-19 vaccines are thought not to be a risk.. Institute's Dr. Kjesten Wiig, Executive Director of VAANZ. If you remove the replicating capabilities of the virus, it still has a major damaging effect on the vascular cells, simply by virtue of its ability to bind to this ACE2 receptor, the S protein receptor, now famous thanks to COVID, Manor explains. In 1947, Salk accepted a professorship at the University of Pittsburgh School of . American Journal of Obstetrics & Gynecology. A lot of people think of it as a respiratory disease, but its really a vascular disease, says Assistant Research Professor Uri Manor, who is co-senior author of the study. 30 Mar 2021.

I am familiar only in part with some of the details you explain.I wonder in the optimistic scenario, which I want to believe, then what triggered the not to many but enough to ask cases of thrombocytopenia? Taken together, it looks as if Operation Warp Speed delivered a questionable vaccine but to recoup their losses Big Pharma still needs to put the jab into peoples arms even though much more is unknown than known! Four years later, while a professor at the Salk Institute, Holley shared the Nobel Prize for his work on how these genetic molecules control protein synthesis. BNT162b2 vaccination induces SARS-CoV-2 specific antibody secretion into human milk with minimal transfer of vaccine mRNA. medRxiv. The vaccine has a limited number of spike proteins, and since its not part of a virus it cannot reproduce. The vaccine-derived spike protein damages the body in the same way as the spike protein produced during viral infection. That could explain why some people have strokes, and why some people have issues in other parts of the body. SARS-CoV-2 Spike Protein Impairs Endothelial Function via Downregulation of ACE 2. Circulation Research. New York: SARS-CoV-2 's distinctive "spike" proteins have been known to infect its host by latching on to healthy cells, but scientists have, in a new study, showed . 18 June 2021.

Reading these comments Jonathan is wrong. Since many cardiovascular diseases are silent killers, those people may have their vascular system very damaged and only show any health problem in the future. Yes, thats why they induce vascular effects in some cases. It yielded the first COVID-19 vaccines, Fact check: COVID-19 vaccines dont produce dangerous toxins, Why Parents, Teens, and Children Should Question the COVID-19 Vaccine. 21 May 2929. If the mRNA vax enters an artery or vein, youre going to experience a very bad vascular event. COVID vaccines and breastfeeding: what the data say, American College of Obstetricians and Gynecologists. The goal of the project is to increase exposure to accurate information about COVID-19 and vaccines, while decreasing the impact of misinformation. As weve reported, the Vaccine Adverse Event Reporting System is designed to detect potential problems thats why its there but it does not show whether the vaccines caused any of the reported issues. An open space or just an open window could reduce the virus transmission. Now, a major new study shows that they also play a key role in the disease itself. Every cure has a starting point. You walk in the park and an infected person coughs near you, so you manage to get few virus particles but keep walking and breathing fresh air. Previous studies have shown a similar effect when cells were exposed to the SARS-CoV-2 virus, but this is the first study to show that the damage occurs when cells are exposed to the spike protein on its own. 4 June 2021. In fact, the antibodies that the mother has can go through the breast milk to the baby and may only serve maybe to protect the baby a little bit. Episode 41. Preprint Authors A Facebook post from the NZ Outdoors Party, which attracted 3256 votes in the 2020 election, draws on the same study to suggest mRNA vaccines "take over cells to manufacture the deadly (spike protein) toxin and this spread throughout much of the body".

William, its been known since early in the pandemic that maybe 50% of people are not susceptible (that is, who dont have visible symptoms). Whats more, we have Dr. Fauci and others President Biden among them too insisting that the fully vaccinated continue to wear their masks. This conclusion suggests that vaccination-generated antibody and/or exogenous antibody against S protein not only protects the host from SARS-CoV-2 infectivity but also inhibits S protein-imposed endothelial injury. Show the data which proves a healthy 10 year old is 50000 times more likely to die from covid 19 vs a vaccine. 27 May 2021. 9. The Salk Institute for Biological Studies is one of the world's preeminent basic research institutions. This is the issue, why create spikes inside cellular machinery? Of course, none of this even begins to account for how vaccines will alter our immune response, for better or for worse, to COVID-19 variants. structures of the SARS-CoV-2 virus, together with proprietary There are animals living in it. My assumption is that it depends on the number of virus particles the person receives within a certain period.If you get in a close contact with someone who has already contracted the virus and spend hours together (like in a hospital room or a small office) theres a high chance for both to replicate and exchange the virus back and forth more and more exponentially and overloading your bodies before their immune systems respond. Jun 21, 2021. Lies tall mountains in which hidden within them lies a sea of water. However, trillions (of these proteins) induced by the vaccine injection have the capacity to create damage in your vascular system. surfactant in COVID-19 patients. The document is about the pharmacokinetics overview seen from lab studies and we can confirm its not about spike proteins from the vaccine resulting in dangerous toxins that linger in the body, Ghazvini said. Yet, a Canadian virus immunologist recently claimed that the vaccines spike protein is a pathogenic protein, a toxin that gets into the bloodstream, then accumulates in breast milk and in a number of tissues and could lead to cardiovascular and neurological damage in adults, children and infants. If you have access to any vaccine, please take it, they are all good to protect you and your loved ones. 10 June 2021. Spikes created inside cells from mRNA are degraded before they exit the cell through the MCH mechanism and the result it the standard immune system hand off is made to fully consume and degrade these protein peptides. 31 Dec 2020. But recent studies in animals and cultured cells have found . Is it a safe assumption that it stays in the shoulder muscle? COVID-19 Vaccine Research at U of G Awarded Provincial Funding. Ontario Veterinary College website. Salk researchers and collaborators show how the protein damages cells, confirming COVID-19 as a primarily vascular disease LA JOLLAScientists have known for a while that SARS-CoV-2's distinctive "spike" proteins help the virus infect its host by latching on to healthy cells. Those instructions tell the cell to make spike proteins. spike protein, SARS-CoV-2 Angiotensin-Converting Enzyme 2 Grant support R01 HL106579/HL/NHLBI NIH HHS/United States . a San Diego biotechnology company to develop COVID-19 While the findings themselves arent entirely a surprise, the paper provides clear confirmation and a detailed explanation of the mechanism through which the protein damages vascular cells for the first time. A post widely shared on social media claims a viral immunologist said COVID-19 vaccines' spike protein means people are being inoculated "with a toxin." Experts say there is no evidence that the . And white !!!! , COVID-19 Vaccination Considerations for ObstetricGynecologic Care. However, this is theoretical; the exact mechanism by which COVID-19 infection leads to cardiovascular symptoms is still unclear., Susan Weiss, a coronavirus researcher and professor of microbiology at the Perelman School of Medicine at the University of Pennsylvania, says there is not much virus in the blood following infection with SARS2., I am quite confident that the spike protein is not a toxin, she told FactCheck.org in an email. while a professor at the Salk Institute, Holley shared the Nobel Prize for his work on how these . Based on this outline, we have reviewed the structure . Thank you Pierre for your explanation! There is no screening or vetting of the report and, to determine if the vaccine was responsible for the problem. University of Guelph. THUS VIRUSES WERE CREATED WITH CERTAIN INTELLIGENCE IN THE PHYSICAL ENVIRONMENT. , which uses electronic health data from nine health care organizations in the U.S. to identify adverse events related to vaccination in near real time. Looking into the adverse event database in the United States, we have found evidence of suckling infants experiencing bleeding disorders in the gastrointestinal tract.. Emails are serviced by Constant Contact. if genetic alterations in pathways that control surfactant COVID-19 vaccine for children. Statement, Canadian Paediatric Society. Saying you can get just as sick with the Spike protein as the Covd-19 virus itself? We thought the spike protein was a great target antigen, we never knew the spike protein itself was a toxin and was a pathogenic protein. The spike protein gets into the blood, circulates through the blood in individuals over several days post vaccination, it accumulates in a number of tissues such as the spleen, the bone marrow, the liver, the adrenal glands and in quite high concentrations, in the ovaries, he said. Other authors on the study are Yuyang Lei and Zu-Yi Yuan of Jiaotong University in Xian, China; Cara R. Schiavon, Leonardo Andrade, and Gerald S.

Founder and currently Executive Editor of Science-Based Medicine Steven Novella, MD is an academic clinical neurologist at the Yale University School of Medicine. I dont know if this should worry me more or the same (?). During a SARS-CoV-2 infection, the NIAID told us, the virus spike proteins can latch onto human cells, allowing the virus to infect them. The mRNA vaccines builds the protein within the safe environment of the host cell structure from the inside outspikes are not created outside this environment. inside the lungs during a COVID-19 infection. vascular wall thickening the hallmark of Pulmonary artery hypertension. Just like the virus. Your mis-information is just as bad as some antivaxxers. over our editorial decisions, and the views expressed in our articles do not necessarily reflect the views of the foundation. LA JOLLAScientists have known for a while that SARS-CoV-2s distinctive spike proteins help the virus infect its host by latching on to healthy cells. The commonality between them is that they all have vascular underpinnings.. My first instinct would be to blame any Fall/Winter COVID-19 spike on the fact that vaccine-induced immunity is temporary with some estimates as little as 6-9 months (the apparent hope, however, is that we can go 12 months between boosters). T cells that COVID-19 vaccines will need to re-create As the old saying goes, where there is smoke there is fire. But since its not part of a virus, it cannot replicate. Dmitry Lyumkis A passion for problem solving. 1s Proposal on Voter Rolls. Research Professor Margarita Behrens is researching the effects of virus-induced maternal immune activation on brain development of offspring, which, given the number of COVID-19 infections worldwide, could reveal a significant effect. Im wondering what this research implies about mRNA vaccines that stimulate the production of spike proteins. . They say things like vaccines are perfectly safe which everyone knows is a blatant lie. While previously working on a vaccine for MERS, a disease caused by another coronavirus, McLellan and others discovered that by adding two proline molecules to the spike protein, they could lock it into its pre-fusion state, triggering a more effective immune response and preventing cell entry. I agree that if the mRNA vaccines themselves stimulate the human bodys cells to produce spike proteins, shouldnt there be some concern that by this process the mRNA vaccines could ultimately cause the same vascular damage? We made a big mistake, said Byram Bridle, a viral immunologist and associate professor at the University of Guelphs Ontario Veterinary College, during an interview with Canadian radio personality Alex Pierson on May 27. Bridle omits this information in his 37-page document, instead saying that detection of the mRNA was downplayed., Now we know the spike protein gets into circulation. Watch this explanation. There is no risk at all because all the vaccines that are being used presently, none of them have the live virus in it. Kaech Would these vaccines not cause similar harm? Had to look down and seen it ! See: https://www.npr.org/2021/02/09/965703047/vaccines-could-drive-the-evolution-of-more-covid-19-mutants. press@salk.edu. document.getElementById("ak_js_1").setAttribute("value",(new Date()).getTime()); SciTechDaily: Home of the best science and technology news since 1998. In the new study, the researchers created a pseudovirus that was surrounded by SARS-CoV-2 classic crown of spike proteins, but did not contain any actual virus. Dan Barouch, a Harvard Medical School vaccine scientist working with J&J on its COVID-19 vaccine, tested six versions of the vaccine in 35 monkeys. Reply. Accessed 29 June 2021. I am not as much worried about anaphylaxis but I read that the latest discoveries and treatments for hives involve anti-coagulants regarding a thrombin factor level. 15 June 2021. Having said that, a more complete answer would depend on the age and health status of the vaccinated individual. The vaccine allows the body to recognize spike proteins so it can learn to fight them, without the risk of a virus that can replicate spike proteins to the point of killing a person. China researchers trying to scare people from getting mRNA vaccines? Wow. Accessed 29 June 2021. SARS-CoV-2 virus RNA. 2. your beta cells then process and read the enzyme with the mrna of the spike to watch out for the foot that will cause all this damage. In reality, the jury is still out which is why these are approved for emergency use, not FDA approved in the usual (years long) tradition. We are slowly getting to the right conclusion. Assistant professor of obstetrics and gynecology at the Washington University School of Medicine in St. Louis. So solving the issues of viruses and other harmful parasites.Can be overcome by locating this sea.There is one man who saw this sea. Incredibly ignorant. Spokesperson, U.S. Food and Drug Administration. The cells . I wonder what this means for spike protein vaccine safety. Germany has lifted all Covid restrictions for entry into the country. See the next video and it becomes all clear. On Point with Alex Pierson. Global News Radio. Dr. Jeannie Kelly, an assistant professor of obstetrics and gynecology at the Washington University School of Medicine in St. Louis and lead author of a study on SARS-CoV-2 antibodies in breast milk following vaccination, told us there is no evidence to support Bridles claims. Theunpublished study found antibodies in the breast milk from all of the workers andminimal amounts of vaccine mRNA.. Using a newly developed mouse model, researchers found that exposure to the SARS-CoV-2 spike protein alone was enough to induce COVID-19-like symptoms including severe inflammation in the lungs. With the live virus, the protein attaches to receptors on the surface of cells and fuses the viral membrane with the host-cell membrane, McLellan said. Editors note:SciChecks COVID-19/Vaccination Projectis made possible by a grant from the Robert Wood Johnson Foundation. Keanna Ghazvini, a Pfizer spokesperson, told us in an email that the document referred to by Bridle, which is mostly in Japanese, is a pharmacokinetics overview of the companys vaccine. concentrations of S1 (a subunit of spike) in 11 of 13 healthy vaccinated individuals and the full spike in 3 of 13, he said in an email, noting that the technology they used is 1,000 times more sensitive than a typical antigen test, so we are really detecting minute quantities of the spike and S1 proteins. (Emphasis is his).
