The Science of Anti-Vaccination


We haven’t talked about the “vaccine debate”
here on SciShow because there is no debate to have. Vaccines don’t cause autism, and they save
millions of lives every year. But there is a debate, whether or not it makes
sense. And a lot of people counter this with ridicule,
but we at SciShow aren’t about judgment, we’re about science, and using it to better
understand the world. We see the anti-vaccination movement as a
phenomenon to be understood. So instead of making yet another statement about how, yes,
vaccines are good, and no, they don’t cause autism, let’s use science to understand
why fewer and fewer people are getting their children vaccinated. I’m Hank Green, and this is SciShow. [Intro] First, let’s discuss how we ended up with
this imagined link between vaccinations and autism in the first place. Autism diagnoses are DEFINITELY on the rise;
now many scientists believe that this is largely or even completely because of more effective
diagnosis, and changes in how the diagnosis is reported. So while diagnoses of autism are increasing,
we can’t say for sure whether the incidence of autism is also increasing. If it is, it
must be because of some environmental factor. Now, when we talk about autism, we’re really
referring to range of developmental disorders, which can affect a person’s ability to communicate
or socialize, or cause them to develop patterns of behavior that become pretty specific and
inflexible. The condition can manifest itself in a lot
of different ways, but you’ve probably heard of them referred to together as autism spectrum
disorder, or ASD. While ASD has been found to have some strong
genetic components to it, there also seem to be environmental factors at work as well. And that’s really the root of this controversy
— we simply don’t know precisely what causes autism. And in the absence of an explanations, people
try to make sense of it themselves. And the way our brains do that is almost entirely
with cognitive bias. A cognitive bias is really just anything that
skews how we process and interpret new information. There are tons of different kinds of bias
— some biases cause us to ignore certain data; others lead us to put too much emphasis
on certain data; they can even drive us to focus on facts that are actually irrelevant
to what we’re observing. But essentially, when we hear a hypothesis
and think, “Yeah, that ‘Makes Sense’” really what we’re saying is “Yeah, that
fits with my cognitive biases.” And so people blame all sorts of things for
Autism…plastics, pesticides, the use of anti-depressants during pregnancy, GMOs, sugar,
gut bacteria, and vaccines. Basically, you start with whatever makes the most sense to
the person doing the hypothesizing. The onset of autism typically happens in one
of two ways. Either parents notice a delay in language development, typically around
the first birthday. Or they notice an apparently sudden loss of existing development, which
might happen all the way up through the third birthday. Now, humans are pattern recognition machines.
We need to be able to figure out what behaviors and strategies lead to positive outcomes. But, even more than that, we’re on the lookout
for things that lead to negative outcomes. This over-weighting of negative outcomes is
a well known psychological effect called “negativity bias.” So imagine you wake up one morning and your
car doesn’t work. Your brain is going to want to know what happened. Did you leave
your lights on? Did you drive though a huge puddle yesterday that maybe shorted something
out? There has to be SOME reason why it won’t start! On the other hand, if you get in a 15 year
old car and it starts up just fine after having had a bad week of barely getting going, you
tend to not wonder “What went right!?” We spend far more cognitive resources attempting
to figure out why a bad thing happened than we do trying to determine why something good
happened. In psychology, the search for these explanations
is called “Explanatory Attribution” and different people have different “explanatory
styles”. Some people are more prone to blame themselves,
while others search for an external event to blame. But one thing is clear: we are very
bad at not blaming anything. It’s not surprising that parents of children
with autism, especially parents who notice a sudden loss of previous development, will
search for a possible cause. And when the most significant recent event
in the health of the child was a vaccination, as can be said for many moments in the life
of a young American, we might identify that as a potential cause and deem that link worthy
of further examination. Now this, is completely logical. The problem
is that over a dozen peer-reviewed papers have found no correlation between autism and
the MMR vaccine, or any other vaccine for that matter. And yet, when you Google vaccines and autism,
a fair number of the results claim that there is a link between the two, and that that link
is being covered up either by the government or by big corporations. A parent, already experiencing frustration
with the medical community’s inability to tell them why this thing has happened to their
child, will, on the internet, find a vibrant community of similarly frustrated people who
share their values and experiences. These communities are full of anecdotes that
draw connections between vaccines and autism. And so, unsurprisingly, some people become
convinced that they have found the reason for their child’s disability. Once their mind has been made up, confirmation
bias sets in. Confirmation bias is simply our tendency to more readily, and with less
scrutiny, accept information, anecdotes, and worldviews that confirm our existing beliefs. And, again, it is a completely normal thing
that every person does. Indeed, trying to convince someone that a previously held belief
is incorrect has been proven to actually increase their affinity for that idea. And so a community is born, and the safety
of vaccines is called into question. And once the procedure for getting a vaccine goes from
the doctor telling you that it is now time for a vaccine — and 99% of parents agreeing
because that person went through medical school — to it being a question to ponder, vaccination
rates will go down. A 2011 study showed that parents who think
about vaccines before their child is born are eight times less likely to vaccinate their
children. Basically, when given an opportunity to research on their own, what they find is
confusing. And when confused, the default choice is to simply take no action. This is an example of yet another bias, called
omission bias. In effect, we judge harmful actions as less
moral than harmful inactions, or omissions. In fact, a frequently cited study found that,
when the choice to vaccinate is framed as an action, the average parent will only vaccinate
their child if not vaccinating is at least TWO TIMES more dangerous than vaccinating. This has to do with our perception of future
regret. Parents report that they’ll feel worse if they take an action and it harms
their child, than if they don’t act and the child is harmed by a failure to act. This perception of potential regret can be
so strong that even bringing up the choice of acting versus not acting seems to be counter-productive. A 2013 study found that attempts to convince
parents to vaccinate their children actually decreased the percentage who went on to choose
vaccination. If vaccination is presented as a personal
choice, instead of a necessity for good public health, then potentially harmful inaction
can seem more moral than potentially harmful action, and vaccination rates go down. Parents
are choosing to “let nature take its course.” And as you might expect, this effect is much
stronger in people with a measurable “naturalness bias.” This is just a tendency to perceive
things that come from nature as being inherently less threatening than things that we invent
ourselves. One way psychologists measure this bias is
by asking a subject if they’d prefer a substance extracted from an herb or one synthesized
in a lab, even if they’re chemically identical. And of course, others have biases against
big government or big corporations, and these ideas about vaccinations fit well with those
worldviews. Confirmation bias at work again. But even people who don’t hold those biases
end up being more likely not to vaccinate if they start doing research before their
baby is born. This is because of another failure of the
human brain. We are terrible at what psychologists call “Risk Perception.” Given the merest sliver of a possibility that
vaccines will cause developmental disorders, parents are now weighing a disease they have
seen, autism, against diseases they have never seen. Since the 1970s, measles has been pretty much
unheard of. Measles doesn’t scare people my age for the same reason a giant man-eating
squirrel doesn’t scare us…we’ve never seen it. Risk perception is basically a science all
on its own, and we have found that vague, future hazards, like the future probability
of an illness, are far less frightening than immediate, specific hazards, like the sudden
onset of autism. So, amazingly, the success of vaccines is
one of the reasons that people are less likely to vaccinate their children. So yes, it turns out humans are complicated,
and this is a complicated problem. Humans are inherently bad at understanding the effects
of self-selecting samples — like online anti-vaccine forums — and often completely unable to accept
that a negative outcome could really be the result of something that’s beyond their
control — and still not very well understood. This is not a “anti-vaxxer” problem; it’s
a human problem. Those of us who trust science or have built
an understanding of statistics and bias simply have had different lives than people who more
heavily weight anecdotes or the opinions of their friends, or strangers they meet online
who feel the same way. So next time you find yourself frustrated
about the decline in vaccinations in America, remember that it’s only because of the dramatic
success of vaccines that we could even think of having this debate, and that those anti-vaccine
activists are being driven by the exact same logic traps and cognitive biases that every
one of us suffers from. Only by understanding and accepting these psychological pitfalls
that we’re all so susceptible to will we be able to solve this problem. And that’s
what science is all about. Thanks for watching this episode of SciShow,

    Okay, so show everyone the stock video of a fretful toddler at the peak of a measles infection, or one that can barely breathe for the violent coughing fits during whooping cough. Show children relearning to walk after meningitis or being buried after pneumonia. Remind people why these vaccines were developed in the first place.

    Anti-vaxxers: The flat earthers of medicine.

    What started as one fraudulent study claiming a single vaccine causes a single issue (autism) has mushroomed into every vaccine causes literally everything, even child abuse (anti-vax groups are claiming shaken baby syndrome and fetal alcohol syndrome are a vaccine injury)… and everyone in the world is lying to you.

    This is the very definition of a conspiracy cult. The first thing a cult must convince you is that everyone else is conspiring to lie to you. Once all objective fact is doubted, they can tell you anything, no matter how absurd, and you'll believe it.

    Think about this: To believe that anti-vax conspiracy theories you must first believe that every single immunologist, virologist, epidemiologist and 99.99% of medical doctors in every country on earth are conspiring to lie to you.

    Debating an anti-vaxxer with their ever moving goalposts becomes a ridiculous game of conspiracy whack-a-mole.

    Here is the single resource that catalogues and debunks every anti-vax conspiracy: (to dismiss this site without addressing the linked sources for every fact given is not an argument. It is denialism.)

    I'm from a less developed african country.
    Got vaccinated against polio, hepatitis and measles, I'm fine, rarely get sick.
    In recent years there has been an increase in mandatory vaccines in my country, like malaria and others very unnecessary like HPV, before a child reaches 15 they've got like 8 different vaccines instead of the normal 2 or 3
    I'm not anti vax or whatever but deep down i feel there is something ingenuine driving this, and it isn't the welbeing of children

    Dude.. You didn’t explain why autism IS actually on the rise. You just said it’s unknown. If you inform the public what is actually IN a vaccine they will be able to make a better decision. Instead you tell humans how their brain works – a psychology class.
    Vaccines contain lead, mercury and arsenic all of which are proven to cause issues in the development of children and they definitely do not aid in the functioning of adults.

    Biochemistry is a very complex subject. There are organs in the body whose function is still not entirely understood (e.g. spleen). The way immunity works is extremely complex. Vaccines have a chance (however small) of developing serious complications not after some years but right after they are administered. And this can’t be predicted due to mentioned complexity. That’s why in countries with democracy people can opt out. Because the chance of contracting some diseases is comparable with the chance of getting a complication from the vaccine. You don’t avoid some diseases because of vaccination but because they are simply very rare in modern society with proper hygiene. Now in Russia for example , the first category of people that stopped vaccinating their kids after it stopped being mandatory were amazingly doctors themselves. It isn’t “advertised“, but it’s a real trend here. Because they know the risk of complications vs the risk of getting a desease in a population with high vaccination percentage.

    Always with the propaganda. Vaccines do carry risks / side effects, many side effects, including infant mortality. Autism is one of the more benign side effects of certain vaccines. Not nonsense. The only incidents you will hear about though are those that occur in China and Russia aligned countries

    October 25, 2019 at 4:32 pm

    Re scientific evidence of the safety and efficacity of vaxx, there has not been one randomized, double blind placebo controlled study. In short: We don't scientifically know if vaxx work or are safe as we don't have the mentioned studies. Only those would allow us to determine whether vaxx or something else is the cause of working. So, vaxx are simply not properly scientifically based. This video shows no science but rather entertainment.

    I like the way this was said, without demonizing anyone and just by helping to understand. As a person who wants a child someday, I don’t care if they’re autistic. Why would I? As long as they’re alive and healthy, I’ve done my job. I’m dyslexic and people have told me that’s a problem, I’m also asexual and a girl. None of these things are things I got to choose. I was born these things. It didn’t make my family question what they did wrong! There’s nothing wrong about being different so long as it doesn’t hurt anyone.

    Parents are being stupid and ignorant in allowing theories to make their decisions for their children. Absolutely ridiculous. Maybe start pressing charges on parents who don't immunize then their child gets sick or dies. How could someone potentially put their kid at risk like that????

    Antivaxxers say vaccines cause autism.
    They can't. The blood doesn't cause autism. Generally, it's due to either psychological trauma or crossed wires in the brain.
    There's literally no way those two can correlate.
    Plus, being autistic ain't bad anyways. Just causes your view to be different to others.

    Don’t treat Autistic people like their condition is worse than causing a pandemic. The man who first said that vaccines cause autism got his medical license revoked. It came to light he made up his “scientific research.” People who have terrible reactions to vaccines (including me, I am allergic to the whooping cough vaccine) are rare. But it isn’t the vaccines fault, just like when someone is allergic to peanut butter. We don’t blame the peanut butter for the cause of it, it’s the persons body.

    Never trust anyone who claims to support science then says "there's no debate" there is ALWAYS debate to be had. Debate is the foundation of science.

    If vaccines were 100% harmless the rabies vaccine would be given as part of the standard schedule and during the small pox terrorism scare everyone who hadn't gotten it (because they were born after we stopped giving the small pox vaccine) would have gotten it.

    The fact is, there is much debate to be had and nothing bolsters the antivaxer movement than the provaxine dogmatic refusal to respect valid concerns.

    Measles has a devastating and long-term effect on your immune system.
    31 October 2019
    Measles is known to make children vulnerable to other infections. Now two major studies of Dutch Orthodox Protestants, who reject vaccination, have discovered why: it massively damages the immune system, making measles even more lethal than we realised.
    “The worst-affected 20 per cent lost more than half the antibodies they could make against more than half the pathogens we tested,” says Mina. The live, weakened measles virus in the MMR vaccine had no such effect in the 32 other children they studied.

    To get their lost antibodies back, Mina suspects those who had measles must be re-exposed to all the pathogens they had already encountered, with the attendant risks of disease. They may even need to receive any previous vaccinations again, as vaccines work by teaching the immune system to make specific antibodies.

    Who's to say that the researchers of those peer reviewed papers were not guilty of conformation bias? It the same principle: those researchers all wanted to prove that vaccines aren't correlated with autism and (likely inadvertently) found evidence that supported their hypothesis.

    HMM YES…So anit vaxxers reply me your information about your arguement. One thing I have to say. ANIT VAXXERS ARE THE APES OF OUR MANKIND. So having a small allergic reaction is better then dieing from measles. So vaccines cause Autism? Here's the thing. IS DIEING BETTER THEN GETTING AUTISM WHEN HIGHLY TRAINED DOCTORS DESTROYED YOUR FAKE PROOF. IS HAVING A SMALL ALLERGIC REACTION BETTER THEN BRINGING BACK SMALLPOX AND INCREASING THE DEATHS CAUED BY MEASLES. Human kind is just stupid. You guys makes fake proof and make random mommy blogs. Non scientific proofed articles with fake doctors. Theory,s AND NOT WORRYING ABOUT CHILDREN DIEING CAUSE YOUR SPREADING THE DISEASE. So dieing from a disease is better then having a small allergic reaction? Ya guys need to get a new brain. Am so mad at anti vax people. Our human race would have been the most developed life in the universe if you didn't show up. Don't give me that "I can choose my opinion" your killing kids by spreading the most prevented diseases on earth. Also about the chemicals in vaccines. THEY ARE SO SMALL THAT YOU WOULD NEED A MICROSCOPE TO SEE THE LIQUID. A MILLIGRAM…A GOD DARN MILLIGRAM IS TO MUCH ALUMINUM IN A VACCINE? There I let out my anger at the anti moms… reply all you want there is no scientific proof that Autism is from a vaccine. It is true that they cause allergic reactions. But is death better? Yup so losing a family member is better then a small rash that could be treated with some cream and medical treatment. God that's enough I let out a lot of anger on these people.

    What a lame video, offering little to no proof of anything you say, completely ignoring valid, medically published studies showing many problems with vaccines. To do a REAL video, an honest debate about the issue, you would have to actually investigate the "anti-vaxx" claims, read some of the published studies, talk to some of the parents whose children's lives were ruined by vaccines. But you won't do that.

    Take a look at what lurks in the MMR vaccine. HIV, cancer causing virus's, complete human DNA etc. Within the GlaxoSmithKline Priorix Tetra vaccine, Proteobacteria, Platyhelminthes worms and Nematoda, 10 more ssRNA viruses,
    Microviridae (bacterial viruses or phage) and numerous retroviruses including endogenous human and avian retroviruses, avian viruses, human immunodeficiency virus and immunodeficiency virus of monkeys (fragments that if inserted into the database turn out to be fragments of HIV and SIV), murine virus, horse infectious anemia virus, lymphoproliferative disease virus, Rous sarcoma virus. Other viruses like alphaendornavirus and hepatitis b virus, yeast virus.
    CORVELVA QUOTE >> Basically, we had to go very deep to trace Rubella virus (in order to prove the presence), using a high sensitivity method. This led us to also come across dozens of viruses and retroviruses, some potentially carcinogens, fungi, yeasts, bacteria.
    Whatever the answer about the amounts, it is certain that there should be none; this again shows that there is NO adequate control over the
    vaccines otherwise these elements would be detected.

    LOOK UP THAT ONLY PARTIAL LIST INDIVIDUALLY, YOU WILL BE HORRIFIED. Shots anyone?
    The list and exert quote was taken from the recent Italian CORVELVA Association study, which used the most up to date Next Generation Sequencing equipment., not 1960s methods of analysing, which is still the ongoing vaccine safety requirement.

    There is a definite link between autism & vaccines. This story is fake news propaganda which is dangerous & irresponsible . The claim that vaccines are safe is part of a huge coverup. Get your facts straight.

    Vaccined dont cause autism because one of the 34 ingredients tested prove so..in 1986 vaccines producers were exempt from lawsuits..since then vaccination quantities increases hmm ofcoure there is no relation here

    The only reason why people think this is because one single Paper in 1995 was published by one doctor who hated a pharmaceutical company. It was outright slander against the pharmaceutical company and had little to no scientific evidence at all. Yet people were stupid enough to believe it, vaccinations should not be a choice they should be a law. I am glad that many schools in America prevent parents from letting their children go to school if they're not vaccinated. Vaccinations allow children to become adults without having to worry about things like polio, smallpox, the plague, or other deadly diseases that would have been a death sentence 500 years ago that are now easily curable and preventable with this advancing medical technology. Hospital should start hanging signs in front of them that say, " This is a place of science, those who believe in the power of prayer and conspiracy theories are not welcome here. If you believe in either of those including that vaccines cause autism get out!" The only way to convince people that vaccines actually work is infecting them with a disease like smallpox or polio, which is easoly curable by vaccination, and if you don't have the vaccination you die. The stupid conspiracy theorists will be forced to believe in the power vacvines and modern medicine. Conspiracy theorists are a danger to this country, they are corrupting the minds of the youth and making the average IQ of the people go down year after year, we would be better off in this country without conspiracy theorists.

    "Parents who think about vaccines before their children are born are 8x less likely to vaccinate their children." So parents who do their own research find reasons not to vaccinate. He assumes it's because they are confused, but I would argue they have a more clear understanding. Using this logic, the Drs "who went to medical school," telling you to get vaccines would be the most confused because they've done the most research.

    Your so ignorant and indoctrinated. Yea you can pull so called facts off the internet but do you have the skill to think critically? The biased idea is the dumbest thing I ever heard and is the biggest excuse to disprove people. These studies are performed by lobbyists who have an invested interest to prove it's not harmful. If you would like to challenge my views I'd be more then willing to debate with you mr science guy

    Even though we refuse to do a study that includes a placebo group and 54% of you are sick. Just do what we say.. We have no liability. Vaccines are safe thats not the problem the problem are all the chemicals and animal dna / fetus dna.

    Recently someone argued that vaccines may not be necessary and that everyone should undergo genetic testing to make sure a vaccine is safe.

    I cant help but to ask. .. seriously though what would you test?

    I don't see much to gain from this person's viewpoint. As said vaccines save millions.

    The message of being aware of our own biases is important. My daughter received a DTaP +polio vaccine on September 9, 2009, and began to have insomnia soon after. To this day, she spends entire nights babbling. It is certainly possible that this had nothing to do with the vaccine, but I find it improbable. There were no other significant changes such as puberty taking place at this time in her life. More evidence came from reading the vaccine insert which listed sleep disorders as a possible side effect (No medical doctors pointed this out to us). More confirmation came from a research study that discussed sleep disorders and general mental disturbances associated with vaccines. Though I do not know that this vaccine caused my daughter's insomnia, I would be very biased against forming any sort of opinion, if I did not reach the conclusion that the vaccine caused my daughter lifetime damage.

    You might wish to consider your own biases. Autism has grown from 1 in 10000 to 1 in about 60, an increase of over 16000%, yet you are happy with the changing diagnosis hypothesis. You do not present any actual research, and you seem to have no awareness of the many, many papers that show connections between a plethora of health problems and vaccines.

    When vaccinations are tested (preferably not by the producer) against real placebos (in stead of other vaccines, adjuvent soups etc which are always used) we will be able to say something scientifically about their safety. But that isn't done. (and of course if they are so safe, why has the vaccine part of the medical industry been exempted from being sued for damages?)
    When a real comparison of unvaccinated and vaccinated groups for their total health picture we might be able to start to really asses the "benefits". That hasn't been done either.
    The young fellow making this video can perhaps be excused because of his age to not know that people like me (74 yr) that lived with and HAD measles find the current panic about measles way out of all sense of reality. (But he should have/could have checked the mortality of measles and how it had gone down 99% way before the vaccines came, and claimed victory)

    This video is biased and not scientific. I’m pro vaccine but this dudes attitude is annoying. “There is no debate” Cmon. Vaccine injuries are real. A good video would show the history of vaccination injuries and the improvements of their safety, ingredients and quality. Instead he just dumps on anti-vax. Low hanging fruit
