Health & Medicine on Khan Academy: No organ quite symbolizes love like the heart. One reason may be that your heart helps you live, by moving ~5 liters (1.3 gallons) of blood through almost 100,000 kilometers (62,000 miles) of blood vessels every single minute! It has to do this all day, everyday, without ever taking a vacation! Now that is true love. Learn about how the heart works, how blood flows through the heart, where the blood goes after it leaves the heart, and what your heart is doing when it makes the sound “Lub Dub.”

@@StevenStGelais First off, "Opinion" doesn't necessarily mean "Fact"; something I learned in Elementary School. Second, Faith in finite-minded humans? Scientists are not gods, and to think otherwise is arrogance of the highest order! You can't glorify certain individuals in high society on such a level, because that will entrench in their sinful minds, making them prideful, and leads to tyranny. Such practice is not Science, It's paganism! It's cult-like! Science (I.E. Common Sense) is to admit that we as humans don't know everything, and we try to learn what we can in the world around us, logically. The Universe doesn't revolve around humanity, and any "Rules on how everything works" that we come up with. Do you realize that "Scientists" don't like the idea of Infinity? Like "Mass of a Black Hole" Infinity? Well then, when you talk about 3.1415 (Pi), as you write out all the decimals; at what point does that random bunch of numbers become 00000000 for the rest of time, thereby signifying an end of Pi? Scientists still don't know, even after millenia of studying that number. So, if we can't figure out all of Pi (Because we can't handle the concept of Infinity); how are we all-powerful, god-like beings, then? We are not! And therefore, what these scientists say on what must be true, or not true should always be taken with a grain of salt. That is Science! It's a very revolutionary field of study, because it (By nature) always uproots long-held traditions at any time. But, that is not always to be feared, as 200 years of Scientific advancements have given us so much in our world today. Still, to say that we must trust whatever people in labcoats say by their word is Anti-Science, Orwellian, and Peak Arrogance! That's it!

Yes, there have. And shifting your hypothesis around serves you nothing. If you have scientific evidence to support that concomitant vaccination causes autism please do the world and all of the “obviously dumb scientifically illiterate scientists” a favor and publish your findings

[@KommentarSpaltenKrieger]

First of all it must be noted that autism ins't a static category. Not only do the terms change (from pervasive developmental disorder, Asperger syndrome, low-functioning autism, high functioning autism etc. to Autism Spectrum disorder (ASD)), but definitions change also (which determine whether or not a diagnosis of autism is applicable). Sometimes the definitions stay the same, but the threshold changes (prior, maybe you had to have 3 out of 5 symptoms for a diagnosis and afterwards it might be 2 out of 5 or 4 out of 5). I am not saying with certainty that this (whether at all or alone) might explain a rise in the diagnosis of autism, but the way a psychiatric condition is understood isn't always the same and thus, there is a slight possibility, that nowadays, just more people are "applicable" for a diagnosis of Autism Spectrum Disorder than maybe 50 years ago. One also has to factor in the amount of psychiatrists working now vs. in the past, and whether or not mental health services have gotten more accessible recently.

Perhaps it should have been called "The Homeland and Lilly Protection Act." Everyone in D.C., it seems, is utterly baffled as to how an ugly little provision shielding pharmaceutical behemoth Eli Lilly from billions in lawsuits filed by the parents of autistic children made its way, in the 12th hour, into, of all things, the 475-page Homeland Security bill.[1] "It's a mystery to us," shrugged Eli Lilly spokesman Rob Smith. It's a mystery to us, too, echoed spokesmen for the White House, the Department of Health and Human Services, and physician-turned-senator-turned-drug-company-shill Bill Frist, who had originally penned the Lilly-friendly provision for a different bill. The haphazard lawmaking also proved baffling for pharmaceutical industry lobbyists, and for White House budget director Mitch Daniels, a former Lilly executive, who made a very public show of disavowing any knowledge of the amendment's mystifying genesis.

[@widddershins]

Thanks for the advice, Jennifer; it's almost a little better than "Google it." However, I feel that when someone claims there is scientific evidence of a particular fact, i.e., "Vaccines cause autism," it is incumbent upon them to cite the study by author, title, journal and date of publication, right there and then, rather than suggesting that other people research the topic on their own.

[@RyluRocky]

@G P This research has specifically only been done from the CHC reporting that the CDC had such evidence rather than showing direct studies conducted directly by themselves. They have been disowned from the scientific community, (when Marianne Williamson who's a part of the CHC was reported and later confirmed lying (www.factcheck.org/2019/08/williamson-misleads-on-childrens-health-vaccines/) about the results she recieved about the increased rate of chronic illness in children that take vaccines and it's possible link to autism.) I'd also like to note that the CHC was founded by an auttorney and still to this day isn't lead by a chemical analyst or doctor.) The CHC in their reports about the dangers of 5G (childrenshealthdefense.org/news/what-you-should-know-about-5g-satellites-how-musks-sci-fi-dreams-are-becoming-our-living-nightmare/) (which the founder has directly supported and approved) claimed the FDA made no studies concerning the dangers of 5G, and it's radiation (which I know is far from Ionized radiation, even humans emit radiation) which is false. (www.digitaltrends.com/mobile/is-5g-dangerous) The CHC is also skeptical about the government and it's motivation with vaccines which has no resarch on vaccines but is used to discredit all other sources of information outside the CHC which is fishy, it's fine if they find some findings as to sketchy stuff the government might be doing but all of their propos directly relates to vaccines. (arstechnica.com/science/2020/04/how-the-anti-vaccine-community-is-responding-to-covid-19/). Do you have any other links not releated to the CHC, that is hopefully lead by a doctor?

The only way to find out is to compare the unvaccinated against the vaccinated. That has never been done.

I would like to make a few comments: 1. Some vaccines accused of causing autism go back to my childhood, over 40 years ago. How can they be causing any recent increase in cases?

Parents do not understand, and scientists do not explain, the brain undergoes developmental changes after birth.

And it's not what they were looking for. ~The study concluded that it would be a good idea to do further research on the safety of the mmr in a one size fits all vaccination programme to see if there were some children who had conditions that caused the mmr to be problematic for them ~The study suggested that continuing with single jabs until further research could be done might be worth looking into instead of withdrawing single jabs in the UK which were still available until 1998 ~This study was 20 years ago why does it not strike her as strange that they have nothing else...did vaccine science just stop in the 1990s! ~You can bet your life that 99% of people sharing this urban myth about Andy Wakefield have not read the study ~Here is the study...! www.thelancet.com/journals/lancet/article/PIIS0140-6736(97)11096-0/fulltext

Your cited figure of 0.1 µg/kg body weight/day is the EPA limit for methylmercury across an entire lifetime. Methylmercury is dangerous because it can rapidly accumulate inside the body (bioaccumulate). That's why it has such a low limit. Thimerosal metabolizes to ethylmercury, not methylmercury. Ethylmercury has not been found to bioaccumulate, but the methylmercury limit is used in absence of any data showing a limit for ethylmercury, and even still it does not exceed the methylmercury limit.

It is rare, but for certain vaccines it happens that some will get a mild outbreak of the disease one vaccinates against. This is inconvenient, but rarely a problem. The much larger problem is that vaccines will not give full protection in all cases, which means that a persons decision to not vaccinate will increase the risk of disease also for others, whether vaccinated or not. This should be given quite some weight when one discusses vaccination.

If vaccines cause autism, why don’t more people have autism? Most schools mandate vaccines in California meaning all those kids got vaccinated. How many people in California have Autism? The argument that autism and vaccines are linked is just plain out ignorance

[@JaimeJohn316]

If you and the rest of us who are vaccinated and are still doing relatively fine health-wise, we ought to be very grateful that we received a harmless PLACEBO and/or a Mild to Medium potent vaccine. Much of the Pro-Vax PROPAGANDA regularly professes "A RARE" adverse vaccine disorder occurred. Well in consideration of the "RARE" 1%... the numbers below show that 1% of a 2 Billion population vaccinated with a potent vaccine still amounts to 20,000,000 (Twenty Million Vaccine-Injured), and 20 Million is FAR FROM "RARE" and very considerable. The following info applies to "ALL" types of JABS across the board including but not limited to: FLU shots HPV shots PEDIATRICIAN shots PNEUMOCOCCAL shots POLIO shots TETANUS shots CV-19 shots etc. shots Regarding Vaccine Placebo Ratios and Vaccine Potency Ratios Consider the following... 50% of JABS = Placebos... Harmless 20% of JABS = Mild Harm 20% of JABS = Med Harm 09% of JABS = High Harm 01% of JABS = Lethal Harm 8 Billion Population and 4 Billion received the CV-19 shots = 50% 2,000,000,000 received 50% of JABS = Placebos... Harmless ...800,000,000............... 20% of JABS = Mild Harm ...800,000,000............... 20% of JABS = Med Harm ...189,000,000............... 09% of JABS = High Harm .....20,000,000............... 01% of JABS = Lethal Harm From Jan 2021 - Dec 2023 there is estimated 20,000,000 (Twenty million) CV-19 Vaccine-induced DEATHS. And 20 million vaccine deaths is a very conservative number.

"Vaccines cause autism; it has been proven in court" I shot my drink out of my nose when I read this line.

[@Lucylee0729]

Ummm it literally HAS been proven in VACCINE INJURY COURT THAT WE, THE TAX PAYERS, PAY FOR. THE FAMILY, AND SINCE THEN HUNDREDS OF THOUSANDS OF FAMILIES, HAVE BEEN PAID BILLONS FOR THESE INJURIES. Jesus. Y'all need to educate yourself by more than Khan academy. It's pathetic.

[@isrbillmeyer]

Yeah... Because what you see firsthand in your children just after the vaccinations is just your imagination. How about this - every parent at the remedial school where my children is has exactly the same experience. Including the headmaster of the school. The one child they have who don't have learning disabilities - guess what - is the one who was not vaccinated. But hey - what the hell does us parents know - right?

[@aestus187]

Bill Meyer Your lack of statistical evidence and your overuse of anecdotal evidence makes this difficult to consider. When no studies are provided, this also weakens your argument.

[@jenniferhawkins1705]

widddershins, A good place to start would be the "Self-Organized Criticality Theory of Autoimmunity" PLOS One study ( Ken Tsumiyama,Yumi Miyazaki, Shunichi Shiozawa). They conclude that autoimmune diseases are the inevitable conseqence of over-vaccination. "Systemic autoimmunity appears to be the inevitable consequence of over-stimulating the host's immune ‘system’ by repeated immunization with antigen, to the levels that surpass system's self-organized criticality."

[@rberka555]

Removing vaccines from the autism equation is like saying "We know O.J. didn't kill Nicole Brown Simpson."

[@kbl4758]

Perhaps I misunderstood the final point but how can 0 out of a group of 1.8 million children have autism???

[@kbl4758]

Ok... “vaccine associated autism” ... still not clear... At that stage they were simply trying to find a correlation between vaccines and autism in order to disapprove or prove causation… So what was the definition of vaccine associated autism?

[@widddershins]

Sure. Menveo. Rotateq. Proquad. Havrix. Comvax. Vaqta. Gardasil. Cervarix. That should get you started.

[@2Truth4Liberty]

Bottom line . . . no one has the right to force another's child to take the risks which are proven to be inherent in vaccines.

[@robbob6028]

Cool, you'd rather have a kid die from a preventable disease than get minor side effects from a vaccination. Which one was more risky again?

[@2Truth4Liberty]

That's a fallacious argument. When something can kill you, by human right to self defense, the choice is to be open, and not forced. Let's see, a vaccine that can kill or abstaining from a vaccine that can kill, which one is more risky ? Ask those who have been killed by vaccines. Oh wait, you can't ask them. Are you aware of the Roclerfeler foundation report (1969?) where they talk about using vaccines to control population size ? Are you aware of the SV40 aspect of vaccines today ? I would guess you aren't.

[@robbob6028]

The funny thing is that the people in-charge of controlling human population are doing an absolutely piss-poor job. There are more people alive today than ever before.

[@2Truth4Liberty]

Aza Sothoth At least you seem to agree that there are "people in-charge of controlling human population". But I think you are jumping to a conclusion about the performance of those people before their actions have time to take full effect. The sterilization is generational such that by the time the masses realize the problem, it will be too late to do anything about it. In some experiments, lab rats become sterile by the third generation. In human terms, that's 60 years . . . so the full thrust of the human "experiment" is still in its first generation for the most part. Those people you say are doing an absolutely piss-poor job would tell you (as they smile at you) . . . ."Just give it time" You want grand kids ? You might get them, but your GMO grand kids certainly won't have grand kids of their own.

[@ayedrey]

the benefits outweigh the so called risks. is right for you to expose your child to diseases? maybe thats the question you should be asking

[@davmus1112]

Omg...I wonder how many of you can see the logic problems with the narrator's story

[@djancak]

What's news to me is that courts should somehow be considered the judges of scientific facts. It's not a good idea to watch the spectacles of human drama and expect those outcomes to accurately reflect reality. If you trust what the media and government bureaus tell you more than you do the scientific method, you will quickly be led astray from truth.

[@pbandjelly1311]

I'm glad you bring up the scientific method. Did you know there have been no double blind, inert placebo-controlled trials on vaccines? They are held to a different standard than medical drugs. They are under a category called "biologics" which skirts the necessity of actually testing them against placebos. Not to mention the faulty logic behind saying it would be "unethical" to compare vacc vs unvaccinated children.

[@widddershins]

Just out of curiosity, don't you get bored signing in and out and voting your comments up and other people's down? don't you have anything better to do? Just curious...

[@anonymous007advice]

Here what the DANISH STUDY really says (Dutch Association for Conscientious Vaccination, The Netherlands) compared the health of vaccinated and non-vaccinated children using various categories and in every category the non-vaccinated children’s parents reported a fraction of the incidence of these events than those of vaccinated children. Sorry but you straight up lied about the Danish study that's a Direct Quote just google it...

[@wizardatmath]

I respect Khan... So am willing to wait for the part where you evaluate the alegation that the CDC doctored the results of their own study on this... The case made in Vaxxed against CDC is either airtight or else a fantastic good piece of artwork.

[@boatbrain1]

Some percentage of people may have a bad reaction to vaccines and undergo some kind of severe brain damage as a result. This has been linked to mitochondrial disease. Only a small percentage of autistic kids have diagnosed mitochondrial disease. It may be that some parents are right, their kid got a vaccine and became autistic, due to some kind of sudden acute encephalopathy. But there does not seem to be much reason to think this is more than a small percentage of cases.

[@rhoadess]

Is there anything out there that does link to Autism rate increase? Perhaps it is just Entropy.

[@CAT-2323]

I already knew vaccines don’t cause autism because of the definition of autism which requires that autism is something your born with (aka: genetically predisposed to). So even with the hypothetical possibility that vaccines could cause autistic symptoms, that, by definition, still wouldn’t be autism. But seeing this broken down even more is fascinating. Many say correlation does not equal causation. But this shows that there’s not even a correlation!

Hugely disappointing explanation. Did corrupt big pharma buy Khan institute as well? Perhaps khan institute is not up to date that the second Doctor co-authorizing the Wakefield study actually appealed all the way to the high courts and won the case that no malpractice had occurred in the "Wakefield Study" study and received his medical license back. As well, it was declared by the presiding judge that the Lancet paper authored by the Wakefield and 12 other prestigious researchers, should be re-published and that the entire Wakefield case had been handled unjustly. Andrew Wakefield has also since been vindicated scientifically by 6 independent research teams from different countries, all having been able to replicate Wakefield's findings, showing he was RIGHT to suggest that more research into links between autism, MMR and IBS is needed. Andrew Wakefield, produced a profound film, VAXXED, which has supported a huge wake up movement around the world. Highly educated doctors, chiropractors, health practitioners, mothers, fathers, are waking up to the reality that there is massive fraud being perpetrated in Big Pharma and government regulatory agencies. People are discovering that we MUST question the safety of vaccines.

Dr. AMY HOLMES: Mercury in thimerosal is stored in the gut, liver, and brain where it becomes very tightly bound to the cells. Once inside those cells, or inside the blood brain barrier, the mercury is reconverted back to its inorganic form. Locked into these cells, the mercury can then do either immediate cell damage or else become latent and cause the onset of autism, brain disorders, or digestive chaos years later. This is also linked to autoimuune disorders, like MS and Guillame Barre.

Throwing the adjective "sound" in front of "decisions" and reaffirming that lawyers use expert testimonials does *nothing* to change the fact that they do not arrive at their conclusions in a scientifically acceptable matter. But now you try to change the topic to something else entirely. Your continuous assertions that I am naive and cowardly are dumb and useless complaints. It is more of an indicator of your own irrational emotional bias, and makes your lack of argument look far more pathetic.
