Which means I am helping up to four hospitalized COVID patients every time I donate. If one doesn’t understand the basics of immunology, then impossible to understand how a vaccine works. There have been studies in the United States, where the regulator, the FDA, is still reviewing the vaccine. Some vaccine experts worry that “unblinding” the trials and giving all of the volunteers vaccines would tarnish the long-term results. This question was rarely considered (but not unheard of) before the pandemic, mainly because the risks involved in not unblinding participants in clinical trials as to who received the placebo control and who received the vaccine was much lower. I find it inconceivable that unblinding is even a consideration at this point, seeing how the core studies have not even concluded yet. All of these statements violate the very basics of what a safety trial needs, which is a control group against which you can compare the effects of the drug or vaccine in question over the long term. Severe Covid-19 occurred in 30 participants, with one fatality; all 30 were in the placebo group.”. As for Denise, following is my exchange with her, not an attack by any standards; but a respectful exchange of ideas. has agreed to consider a faster, but limited approval, known as an emergency use authorization, based on early results from clinical trials. Let’s just say that the answer is much more complicated than Mercola describes. But, then, like the dinosaurs died because a meteor hit earth in the exact worst spot imaginable…. We argue that, once proven efficacious, vaccine makers and researchers have an ethical obligation to unblind the placebo groups of COVID-19 vaccine trials … In this article, he started out with a clever ploy, to oversimplify the complex issues behind the ethics and science of clinical trials in a way to cast doubt on the efficacy of COVID-19 vaccines and the motives of the vaccine manufacturers, who are portrayed as trying to “betray science”. Good clinical trial investigators try to design their trials in a manner that minimizes this “dropout” rate or at least tries to make sure that any dropouts are distributed as equally between all arms of the study as feasible. Some of his comments just go way to far over the line of any type of human decency. mercola is small-time. It turns out that crossover trials are quite common in oncology clinical trials. Anthony Fauci proposed it as a way to get large-scale randomized data on how long immunity lasted, without leaving people on only placebos. Are any of the COVID-19 vaccines self-spreading, self-propagating, transmissible vaccines? Mercola selectively quoted Goodman in his article, but if you go to the interview, you will find that the issues involve far more than whether the two groups in a COVID-19 vaccine trial will behave the same with respect to risky activity: If you watch the 22-minute video you’ll quickly see just how complex the issues involved are. The self-unblinding of participants spells trouble even if they stay in the trial, geneticist and cardiologist Elizabeth McNally, MD, PhD, of Northwestern University, told MedPage Today. Separate guidance for COVID-19 vaccine trials is being agreed with each research team. And just plain dishonest when you write: “Then Orac tries to dissuade you by posting this On April 19 at 0918: “As longtime readers know, I definitely do not like pedants, but in this case I’ll allow it.”. The variant makes up a far smaller proportion of all COVID-19 cases in the U.K. and U.S. Across all three trials, Novavax will conduct the crossover stages without unblinding the studies. But, antibodies take up to 10 days to recognize and attack a new invader, regardless of how healthy someone is. [97] The conversation around the booster doses of COVID-19 vaccines gained momentum after people in many western countries were inoculated with the booster dose, or the third dose. We rely on advertising to help fund our award-winning journalism. The problems with unblinding cut both ways, and Mercola ought to be salivating over the possibility of attributing any and every adverse event to the vaccine, but no one said consistency was a feature of antivax rhetoric. His talking point comes in the form of an article entitled “Vaccine Makers Destroy COVID Vaccine Safety Studies”. We urge you to turn off your ad blocker for The Telegraph website so that you can continue to access our quality content in the future. Even Jonas Salk balked at the idea of giving people placebos when researchers designed a trial to test his new polio vaccine in 1953. First of all, no, the vaccines are not “gene therapy”. Pregnant people were shut out of Covid vaccine trials — with disastrous results. This is the key passage of Mercola’s article. Then, I’ll discuss how Mercola, as antivaxxers so frequently do, takes what is really a very complicated question of science, clinical trials, and ethics, and oversimplifies it in order to feed a conspiracy theory. Participants in the placebo arm have been crossed over to receive the first dose of the vaccine, he noted. You write: “But as an outsider I will try to show you what the rest of the visitors to this site see.”. While deaths were unavoidable at first, now that vaccines have been proved efficacious they are not. Madhi is the local lead investigator in AstraZeneca’s and Novavax’s respective Covid-19 vaccine clinical trials. That brings up yet another concern. He wants to sell his book on COVID-19, though, and so can’t help but make the grift behind his fear mongering obvious. As you can see, the hubris is epic, the arrogance of ignorance incredible. Given all that information, now what would you do if you were a participant in one of these clinical trials? This was done to preserve the blinding of trial participants and other staff – … When considering anything Mercola writes, remember two things. Why is that? These results, together with the induction of both humoral and cellular immune responses, support large-scale evaluation of this candidate vaccine in an ongoing phase 3 programme. How many elevators do they have in Cuba? Yep, I am retired; but currently, as I’ve mentioned in several comments, proof-reading and making editorial suggestions for a colleague’s over 800 page next edition of a best-selling undergraduate microbiology book. says: I was actually a volunteer in the phase 3 clinical trial for the Moderna mRNA vaccine. Imagine you’re in charge of this massive clinical trial. The vaccine was 90.7 percent effective in preventing symptomatic COVID disease, based on 16 infections in the placebo group and three … I also know that ORAC was a fan of Rush Limbaugh at one time, so is familiar with Limbaugh’s hook . The action will enable participants in the placebo cohorts of the original trials to get vaccinated without unblinding the studies. That this particular surgeon has chosen his nom de blog based on a rather cranky and arrogant computer shaped like a clear box of blinking lights that he originally encountered when he became a fan of a 35 year old British SF television show whose special effects were renowned for their BBC/Doctor Who-style low budget look, but whose stories nonetheless resulted in some of the best, most innovative science fiction ever televised, should tell you nearly all that you need to know about Orac. And Christine refuses to even consider that she cannot possibly be absolutely certain that a vaccine was responsible for her infants tragic death. And I continue to fill out the weekly questionnaire and monthly phone calls and will return again for blood tests. April 3, 2021 at 1:08 pm There is a problem with a cross-over trial, though, as discussed by Hilda Bastian: Now, this has real limits. The WHO ignored their own commissioned report that found using ivermectin could cut COVID-19 deaths by 75% and instead cherry-picked data to support the subsequent recommendation that the drug be used only in clinical trials Either way, when the data safety monitoring committee finds a clear difference between the groups in a clinical trial, there is an ethical dilemma: Stop the trial and potentially knowingly harm one group or continue the trial to get the most rigorous science. It could make the vaccine look less effective than it is.”, Goodman, the Stanford University epidemiologist, said that those who unblind themselves via antibody tests “undermine the contributions of fellow trial participants and make this behavior seem acceptable by violating the trust within the trial, potentially weakening the ability to do other trials in a scientifically valid way as well.”. — often business sites like Manta, Spokeo have money/ staff details His talking point comes in the form of an article entitled “Vaccine Makers Destroy COVID Vaccine Safety Studies”. Research output: Contribution to journal › Letter › peer-review. The action will enable participants in the placebo cohorts of the original trials to get vaccinated without unblinding the studies. This tactic has, in particular, been weaponized in the era of the COVID-19 pandemic, largely because of uncertainty in the science and the fast pace of scientific discovery. Will it forever sabotage the science behind COVID-19 vaccines? Novavax plans to follow participants for up to two years to assess the durability of protection. Let’s just say that the answer is much more complicated than Mercola describes. 27, No. Eat a “clean,” ideally organic diet. I was introduced to 4 people who just wanted to argue about Jews/theHolocaust/Hitler/NAZI’s, gun control, abortions and about 90,000 words of non related stuff, and one person who repeated the the line ‘woo-misters’. This text distinguishes itself with its accessible and broadcoverage of statistical design methods--the crucial building blocksof clinical trials and medical research. Again, this is an unprecedented situation with respect to vaccine clinical trials that Mercola is massively oversimplifying and using to impute nefarious intent to the clinical trialists, the vaccine manufacturers, and the regulatory agencies that allowed these vaccines to be distributed. Ethical Considerations for Unblinding and Vaccinating COVID-19 Vaccine Trial Placebo Group Participants. On 21 May 2020, NIHR set out a frameworkto guide the restarting of NIHR research activities which have been paused due to COVID-19. Vaccine trials, as per regulatory requirements, are designed to follow-up with participants for 1 to 2 years, which is the case with all three currently approved vaccine candidates [18,19,20].This post-marketing surveillance allows for gathering of data on long-term efficacy and side effects [].As such, half of the participants of all current and future COVID-19 vaccine trials … It’s all about the quackery and the grift. April 19, 2021 at 9:18 am Now Natalie is going “you’ll have no arms left” and the rest of the world is going “tis only going to be a flesh wound.” {they’re months ahead of the rest of us} And we foolishly sacrificed half the brave initial trial participants for spit. “I’m a huge vaccine advocate, so I kind of jumped at the opportunity” to enroll in the Pfizer-BioNTech phase 3 vaccine trial… HOWEVER, I think that when these entrepreneurs unabashedly brag about their businesses and RE interests, followers applaud their success perhaps taking it as proof of being their right. Just one reference that does a good job summarizing what is currently known about vitamin D and COVID. This does have the tendency of people to ignore your post (some which may contain useful information).”. I was introduced to 4 people who just wanted to argue about Jews/theHolocaust/Hitler/NAZI’s, gun control, abortions and about 90,000 words of non related stuff, and one person who repeated the the line ‘woo-misters’.”. On the one hand, unblinding a vaccine efficacy trial compromises the ability to gather robust scientific data on important issues, such as how long a vaccine protects a person against COVID-19. Scott doesn’t just misquote us, he ignores most of what we write and just cherry picks stuff taken out of context. I often observe that we have areas of overlapping studies in psychology and biology. Educatiis a start but doesn’t mean that you automatically have carte blanche to say whatever you will but most times, you learn – especially in SB fields like those mentioned- how to cite research, understand statistical analyses and come to conclusions. The idea was if the group that was vaccinated earlier starting to get Covid-19 while the later-vaccinated group didn’t, you’d get the signal that immunity in the first group was waning. The problems with unblinding cut both ways, and Mercola ought to be salivating over the possibility of attributing any and every adverse event to the vaccine, but no one said consistency was a feature of antivax rhetoric. Trials of vaccine candidates using mRNA delivery systems developed by Pfizer-BioNTech and Moderna have shown … Given the stakes of the Covid-19 pandemic, the F.D.A. Tens of thousands of people around the world who have participated in phase three trials of Covid vaccines remain unsure as to whether they received a placebo or the real thing. It involves the balancing of the ethical imperative to minimize harm to the individuals in the clinical trial versus the scientific imperative to complete the trial to make the science as rigorous as possible. As for “long winded,” even in college on exams we had essay questions requiring 1,000 words. Sure, it won’t hurt to eat an organic diet and minimize processed foods, but there’s no good evidence that doing so will prevent or treat COVID-19. Before you answer the question of whether unblinding is a good idea or not, consider also that more and more doses of multiple vaccines have become available, meaning that clinical trial participants who suspect they received placebo could easily just go and get vaccinated with one of the other vaccines—or even the vaccine whose clinical trial they participated in! But would you call mysorean rockets rockets ? Other information gaps will include more comprehensive assessments of short-term safety, knowledge of whether waning of vaccine-induced protection may lead to vaccine-enhanced disease if a vaccinee becomes infected on exposure to SARS-CoV-2, information on protection against clinically severe forms of Covid-19, and knowledge of any associations between the degree of protection and the recipient’s age or coexisting conditions. @ Prohias, You write: “You on the other hand are retired, you walk your dog, which pretty much leaves you to post stuff here (and other places)(if you type 40 words a minute it has got to take you hours just to type your responses to Scott, Natalie, Kay, Charles, Narad, Denice et al.) It is not. I agree – and I should have made that clear in my comments. Large-scale deployment of COVID-19 vaccines will seriously affect the ongoing phases 2 and 3 randomised placebo-controlled trials assessing SARS-CoV-2 vaccine candidates. He gives the game away in the very same article by saying this about reports of adverse reactions to VAERS: Keep in mind that we still do not know the percentage of adverse effects being reported. The design of the South African crossover trial will enable Novavax to evaluate whether an additional dose of its vaccine improves protection against B.1.351. It also said that being in a Covid-19 vaccine trial should not disadvantage people, and all vaccine trial participants should be treated as fully vaccinated. Will it forever sabotage the science behind COVID-19 vaccines? “The purpose of blinding the participants is so that they don’t change their behavior and decide to take more risks in terms of getting COVID,” she said. Under normal circumstances, there would be little pressure or ethical imperative to unblind a vaccine trial because the risk to the control group would be very small. That’s really up to other folks [I sometimes try to contribute little bits in that direction in the comments]. Before you answer, consider two other issues, one of which was cited by Mercola from a MedPageToday article on self-unblinding of participants in the Novavax trial: On social media, participants in Novavax’s ongoing trial have been hotly debating whether it’s a good idea — or ethical — to unblind themselves by taking commercially available antibody tests. “I would feel that every child who is injected with a placebo and becomes paralyzed will do so at my hands,” he complained. Can anyone here provide me with these data? As well as looming questions about the duration of immunity, there are concerns that vaccine developers may never generate enough data to receive full approval from regulators if they unblind their trials too soon. Ask yourself if it is ethical to require those participants to remain in the dark and unvaccinated in the context of nearly 300 million doses of, for example, the Moderna and Pfizer/BioNTech vaccines alone having been distributed in the US. It is also not about “hiding adverse events” to unblind the entire control group. Some of us try to illustrate how alt med prevaricators/ anti-vaxxers live in luxury, running empires selling BS and hiring staffs of IT specialists and lawyers.by leading readers to websites showing estates, warehouses/ packaging facilities and lists of jobs available.
