The Side Effects of Vaccines – How High is the Risk?


Vaccines are celebrated
for their part in fighting disease.
But, a growing group of peopleseem to believe that they endanger
our health, instead of protecting it.
The Internet is full of stories
about allergic reactions,
the onset of disabilities,and even death following
vaccination appointments.
And, it’s true vaccines can have side effects.Let’s look at how they work,
and how dangerous they really are.
Your immune system is a
complex army of billions of cells.
Soldiers,intelligence cells,and weapons factories.Every day, you’re attacked countless times,but your immune soldiers alone
usually deal with that,
so you don’t even notice.If an infection becomes serious though,our intelligence cells gather
intel about the attackers
and activate our weapons factories.You know the weapon: antibodies.They’re like targeted missiles produced
specifically to combat the invader.
Unfortunately, this process takes
several days to complete.
That gives intruders
a lot of time to do damage.
Contrary to popular wisdom,what doesn’t kill you doesn’t make you stronger.Our bodies really don’t want
to fight serious wars over and over,
so our immune system came up
with an ingenious way
to get stronger and stronger over time.If we fight an enemy that is dangerous
enough to trigger our heavy weapons,
our immune system automatically
creates memory cells.
Memory cells remain in our body
for years, in a deep sleep.
They do nothing but remember.When an enemy attacks for a second time,the slumbering memory cells awaken,and order coordinated attacks
and the production of antibodies.
This is so fast and effective,that many infections you beat once
will never make you sick again.
You might even be immune
against them forever.
Which is also why little kids are constantly ill;they don’t have enough memory cells yet.And this beautiful natural mechanism
is what we build on when we use vaccines.
How Vaccines WorkAs great as memory cells are,obtaining them through an infection
is unpleasant and sometimes dangerous.
Vaccines are a way of tricking
our bodies into making memory cells,
and becoming immune to a disease.They pretend to be a dangerous infection.One way of doing this is to inject
invaders that can’t do harm.
For example, by killing them,
or by ripping them into pieces.
Our immune systems deal with
these kinds of vaccines pretty easily.
Sometimes, it’s necessary to make
our immune system work harder though,
to produce even more memory cells.Live vaccines are the real deal.An enemy that can punch back is
a bigger challenge than a dead one.
But this also sounds like
a sort-of horrible idea.
What if the germs win?To avoid that, we breed a sort-of
weak cousin of the real germ in the lab.
Just powerful enough to annoy the immune
system, and create enough memory cells.
Okay, so these are the basic
principles of vaccine use.
They provoke a natural reaction in our bodiesthat makes us become immune
against very dangerous diseases.
Some, like the flu virus, mutate so oftenthat we need a new vaccine every year,but most vaccines protect us
for years, or even a lifetime.
But, there’s a catch.Like everything in life,
vaccines have another side:
Side effects.What are they, and what happens
if your child develops one?
The Risks of VaccinesIt’s complicated to directly compare the side
effects of vaccines with the effects of diseases.
For example,hundreds of millions of people are
vaccinated against measles in the West,
but there were only 83,000
cases in Europe in 2018.
So, with numbers that different,
even mild side effects can seem scary
compared to the bad effects of a disease
that we don’t see as much anymore.
Before the measles vaccine
became available in 1963,
virtually every single child on Earth
contracted measles at some point.
An estimated 135 million cases in the 1950s.Every single year.But are measles really that
dangerous in the year 2019?
With our advanced healthcare
and new technologies,
are they worth the risk of vaccine side effects?Let’s do a thought experiment
based on real numbers.
Imagine a developed country
in a parallel world.
It has good healthcare but
people stop vaccinating.
In this scenario, let’s say ten
million children caught measles.
What happens?Nine million eight hundred thousand, or 98%,
will get a high fever and a very unpleasant rash.
Up to 800,000 of them, or 8%,
will suffer from dangerous diarrhea.
700,000, or 7%, will suffer from an ear infection,
which can lead to permanent hearing loss.
600,000 kids, or 6%, will suffer from pneumonia
— the most dangerous effect of measles.
It, alone, will kill 12,000 children.Up to 10,000 children, or 0.1%,
will get encephalitis.
2,500 kids, or 0.025%, will contract SSPE,a disease where the measles
virus lingers in their brain
and kills them a few years later.Taken together,around 2.5 million children will suffer from
somewhat serious effects from measles.
And, about 20,000 children
will be killed by measles.
It doesn’t stop here though.The kids who beat measles are left with
a severely damaged immune system
that needs a lot of time to regenerate.Time for other diseases to do further damage.Aside from that, what’s almost guaranteedis that your kids will have a really
bad time for about two weeks.
Okay, but what about vaccines?It’s only fair to look at these risks, too.So, let’s repeat our thought experiment.But, this time, we vaccinate ten
million children with MMR.
What would theoretically happen here?After being vaccinated,of our 10 million kids,
around ten percent get a fever.
500,000, or 5%, will get a mild rash.Up to 100, or 0.001%,might have a serious allergic reaction
and will have to be treated.
Up to ten boys, or 0.0001%,might get inflammation of the genitalia.And up to ten kids in total, or 0.0001%,might get the most serious
side effect: encephalitis.
So, we vaccinated ten million kids.In total, around one hundred and twenty had
side effects that were somewhat serious.
Thanks to good medical treatment in developed
regions, almost all of them will be fine.
What about autism?The connection of autism and vaccines
stems from one source
that has been disproven countless times.We’ll link to further reading
and videos in the description.
But, in 2019, it’s fair to say that
vaccines do not cause autism.
All right, but what about deaths?It’s really hard to say if even a single one of
our 10 million vaccinated kids would die.
We really did look hard and
talked to a lot of different experts.
If we ignore self-reporting,we could only come up with a tiny
handful of documented cases
for all the hundreds of millions of children
who received the MMR vaccine since 1971.
Measles are many, many thousands of
times more dangerous for your child
than even the absolute worst
case of vaccine side effects.
You have to search for lethal vaccine side
effects with a huge magnifying glass
and, even then, it’s very hard
to find confirmed cases.
While, deaths from measles
are real and easy to find.
In 2017 alone, 110,000 people
died from measles worldwide.
Statistically, today,
300 children will die of measles.
One since this video started.You can compare vaccines to seatbelts.Are there weird freak accidents where
someone gets killed by their seatbelt?
Well, yes.But, do you personally think it’s safer
to not put a seatbelt on your kid?
Wait a second!What if your kid is actually allergic?What if none of the things we’ve said
applies to your specific situation?
In this case, you need to become the
greatest vaccination promoter of all.
Because if your children can’t be vaccinated,
only the collective can protect them.
This is called herd immunity,and it’s the only thing that
can protect your unvaccinated child.
Herd immunity means that enough
people are immune to a disease,
that it can’t spread, and dies
before it reaches its victims.
But to accomplish this for measles alone,95% of the people around you
need to be vaccinated.
ConclusionThe problem with the debate about vaccines
is that it’s not fought on a level playing field.
While the pro-vaccine side argues
with studies and statistics,
the arguments against them are
usually a wild mixture of gut feeling,
anecdotes, and misinformation.And feelings are often immune to facts.We’ll not convince anybody
by screaming at them.
But we can’t hide from the reality
of what anti-vaccine conspiracies do.
They kill babies too young to be vaccinated.They kill healthy children that are just unlucky.They bring serious diseases back
from the verge of extinction.
And, the biggest side effect
of vaccines is fewer dead children.
Vaccines are one of
the most powerful tools we have
to eradicate the monsters that
most of us have already forgotten.
Let’s not bring the beasts back!Vaccines are celebrated

100 thoughts on “The Side Effects of Vaccines – How High is the Risk?”

  1. Dive into sources and further reading here: https://sites.google.com/view/sources-vaccines

    Vaccines and their side effects are a hard topic to cover – we know we keep saying this, but this case especially, there were a lot of things to consider. You can’t blame people for being worried, so we wanted to take their concerns seriously.

    Because it is impossible to cover everything there is to know about vaccines in a ten minute video our sources are extra extensive and explain a lot of aspects in more detail, with an extra focus on further reading.

    So if you want to dive in deeper or have more arguments at hand for your next heated discussion, here you go.

  2. Vaccines damaging health is not a new idea. In the 1950s it was recognised as a problem and there was even an organisation for vaccine damaged children. I'd like to know when measles became a life threatening illness as it certainly wasn't when I was growing up? Measles can be very serious for malnourished children but fortunately there are few of them in Britain now.

  3. the boring way of saying zero zero zero is a risk of 1 out of 1000 child GETTING A PERMANENT BRAIN DAMAGE FROM MMR VACCINE

  4. I love how, when sorting by newest first, all the positive comments have a couple likes or whatever, maybe one comment, and all of the comments bringing up possible bad points (or just being plain stupid) have full comment chains where people try to teach them. To those of you helping, teaching those who don't understand, I salute you

  5. I honestly love how you turned this boring and really hard/un-fun to learn topic into a RTS game.
    This video made me research about Cells 'N' Stuff more. So thank you. And have a nice day Kurzgesagt.

  6. Do people really thing that unvaccinated kids dies in there childhood years? You people never heard about African and Latin Americans — poverty— not having healthcare and kids still become adults?

  7. Just got the yearly flu vaccine today. Before you call me out for getting it "early", bear in mind that A. I have asthma, B. I take inhaled steroids for said asthma which can weaken immune systems, C. My job brings me into contact with many hundreds of people DAILY, and D. My worst time of year allergy-wise is coming up within weeks from now. A chest constricted from inflammation and sinuses swollen from pressure are fine targets for an early flu season.

    Normally my asthma is a mild nuisance, but my lungs are truly my weak point when I get sick. Before I started to take inhaled steroids, I was so used to coughing for up to five months afterwards that my new doctor at the time was startled when I mentioned it in passing. "That is not normal! Your asthma's out of control!" I had never considered it since, again, aside from illness it's normally a mild issue except in late fall.

    It's a double-edged sword, but if I do get sick (which has been more often as steroids can have such an effect on my immune system), it is a month or six weeks of coughing instead of five months. I usually am just fine over the summer, but the time is coming up very soon that my risk goes waaaay up. Minimizing my chances is the best I can do.

  8. How does this affect the evolution though? It should be considered that an infinitesimal change in our nature has fatal changes in the future.

    A person that wasn't vaccinated and survived through everything on their own will have a way better immune system than someone who got vaccinated. If that keeps up our immune system will rapidly decrease in function and will lose to the mutating viruses. That is if we vaccinate ourselves with WEAKENED viruses and bacteria, which we do.

  9. "Vaccines can cause side effects." – Yes like surviving, growing up to adulthood without needing special machinery to keep you alive.

    While it's true there can be complications from getting a vaccine and nothing is 100% effective even if they caused autism, which they don't, it's better to have an autistic child than a dead one.

  10. (note this is satire) Ya know im an antivaccer cause not vaccinating kills people and those obnoxious little shits are everywhere

  11. It really doesn’t matter about people that don’t vaccinate there children and there self they will die and get remove from the gene pool smart but they will probably bring back something like pledge or polo etc

  12. I understand fighting antivaxers needs simple arguments. There is however a 3rd category of skeptical people who don't take for granted any arguments.

    Just a few considerations for another video that is for "smarter" people.

    1. If we had many parallel universes with 100% vaccinations and 100% without vaccinations in which ones do you think there is a higher chance of finding all people dead in that universe? (We must be aware that people make mistakes and have limited understanding and as long as we put our trust in a hand of scientists and producers without risk mitigation strategies mass extension is a serious "side effect").

    2. The parallel universe example in the video is nice to give some number perspective. It would be nice if we had more examples in which kids are vaccinated at ages of 1, 2 or 3 years.

    Considering autism is rising without any known cause, maybe we can wait a little, to wait to see if people have a normal child. If you vaccinate a 6 months old that can complain it's hard to see the side effects of your vaccine.

    3. We must be aware the 'unfair battle' is fought between large companies and government institutions that have failed in the past for various reasons like "making a profit". See how long it took to prove tabacco industry was causing harm.

    4. Is there a transparent place where people can submit their stories? Or get access to data to run their own stories?
    Any video on vaccinations should mention these links. I know a case in Romania where a kid had high fever with convulsions and the hospital refused to register the data in the vaccine database.

    4. Antivaxers put pressure that make the industry a better place. Without them we would have used Mercury in our vaccines in the present.

    5. I will stop here, but the problem is so complex and this shouldn't be treated like a 2 side fight against each other. All the views should be welcomed… 🙂

  13. Do Not take any vaccinations, This is the standard deceptive way you are given the establishments biological warfare infections.~Dr William Kelly, Killed by assasination for exposing these creeps

  14. You should make a better video which addresses the real issue instead of sidestepping it. Only idiots argue that vaccines are good, vaccines are bad. More intelligent people would assess the merits and problems of vaccines, both historically and in the present day including how vaccines have changed over time, which would include a breakdown of the composition of the vaccines, and would compare the types of vaccines we currently use to alternative vaccine compositions e.g. adjuvant free vaccines vs different types of adjuvants, and to alternatives to vaccines alltogether. Also it's great to study the effect of vaccines on different types of people like those with a genetic mutation causing vulnerability to outside toxins or to hyperstimulation of the immune system and what's the ideal course of action there. Let all the morons keep patting themselves on the back for reciting "vaccine r good antivaxx r dumb" but an impartial and well researched scientific breakdown of the vaccinations we most commonly use today would be great. You would have to include things like cost cutting and profit maximisation vs focus on health too when discussing the manufacturing process and perhaps delve a little into how the industry and regulations could be improved there.

  15. A mi me dio varicela.. Un virus q es muy agresivo y desagradable. Y la verdad sentia q moriria. Fiebres horrible con ardor y dolores. Fue una tortura. No podia beber agua sin dolor. Y no dormi por 3 dias. No es una enfermedad mortal pero si muy virulenta.. Y sufres mucho. Si hubiera sabido q era tan dolorosa me hubiera vacunado. Ahora soy inmune. Pero imaginense enfermedades q son aun mas peligrosas q la varicela. Deven ser el infierno. Por eso vacunense.

  16. Such a dumb and weak video – all vaccines have side effects, sometimes these side effects are lethal or result in life long disablement/brain damage

    There are also a huge range of less severe side effects

    Our attempts to track and record the incidence of these side effects are pathetic – but there are an untold number of parents out there all around the world warning of the dangers of vaccination and saying the exact same thing

    Are these potential side effects worth it? That's what this video should have covered.

    If you want to risk severely harming your perfectly healthy child just to (perhaps) avoid things like measles, flu and chicken pox then go for it – I won't be doing that until we understand more about why some children are so severely harmed by vaccines

  17. I have actually never been vaccinated, I am 15 and I still fear for my life lol. My mom is an an anti Vaxxer so yeah. Although a good thing that’s come with it is now I’ve built up a strong immune system.

  18. If you're really that scared if side effects talk to your doctor,most side effects are caused by allergic reactions that are either major or minor that cause issues. Check with your doctor if you're allergic first. If yes then you fall under the people who have to be protected if no then vaccinate unless you have a disease or a condition that will only make it harm you for example immunodeficiency is a reason to not vaccinate.

    To my knowledge there's no mental disorder or illness that can stop you from having vaccines or causes a sideffect so please talk to your doctor about it.

    Some sideffects I know of that aren't talked about in this video are extremely rare to the point where if you suffer them most doctors will decide that vaccines are dangerous for you AS A PERSON because you either have an allergy that could cause it or something else.

    Please keep the people who actually need to be protected separate with the people who think they rather risk a high chance of dead or if they don't die multiple weeks of suffering. Because the former is someone who recognizes the importance of it and is thankful people vaccinate to keep them safe and the latter are people who are either misguided people who can learn or people who refuse to listen no matter what

    That's just what I wanted to say

    Also autism speaks isn't the place to go for autism info, people with autism aren't sick they're just different and have different ways to learn and fit in depending on the people who are around you and the severity of it (the same goes for people with add and adhd)

  19. Chicken pox, cause shingles….. Which is fucking painful. To lessen or prevent.. "cough cough" vaccination is now available. Sorry Gramps you were born too early.

  20. like honesty these mindless anti vaxxers aren't even doctors like they only did research on google and google isn't a good source of info cause some might be false

  21. My immune system is like an unstoppable army…I never get sick almost absolutely never not even a simple cold…but my intelligence cells are retards so on the rare occasion that I do get sick it lasts like 3 times longer than in everyone else

  22. Kurzgesagst : explain by a + b why people should get vaccinated

    0,1% Antivax viewers : DISLIKE, CONSPIRACY, FLAT EARTH, PAID BY GOVERNMENT

  23. Anti vax: Vaccines causes Autism!
    Me: No-Vaccines causes Death at the age of 3. But it seems you rather have your kid die early rather than contracting a mental problem, which you heard from an actual autistic psycho man you found in the streets instead of actual doctors Karen, I will promise to visit your kids every year at the anniversary of their death just to say "Sorry that you have such an insensitive and stupid parent".

  24. I love this video so much! My only question is what song is in the ending credits. I really like it and its been stuck in my head for days

  25. Pfft what about the fact that milk protein in the DTAP vaccine that gave me a milk protein allergy, is that a side effect?

  26. Ok but what this video fails to mention is that vaccines are not 100% effective. So you could literally get the MMR and still get the measles. A big problem I have with the pro-vax community is they tend to shun ant-vaxxers like they are always responsible for the outbreak of disease when they isn't the case. MMR is only 93% effective against measles and 91.1% of the US. population has received the MMR. So therefore in the US, non vaccinated people only account for less than 2% more of the population susceptible to measles. I'm neither pro or anti I just don't like the stigma against anti-vaxxers.

  27. I don't understand how this video is supposed to "convert" anti-vaxxers.
    Their whole problem is that they don't trust studies like the one mentioned in the video, so telling an anti-vaxxer to "ask your doctor" or "look at the proof" doesn't work when the see them as voided.

    Why not instead try to void their "sources" instead? That way they'll have to accept vaccinations

  28. How many of you read the vaccine insert and look up the ingredients inside these shots? No one should trust a product that the government gave legal immunity to vaccine manufacturers.

  29. The last time I got a vaccine, I left the doctors and then got hit by a car. Obviously the vaccine caused all my broken bones, how would I get them by getting hit by a car??? If you don’t want all your bones to be smushed, don’t get a vaccine.

  30. pauses video and infects myself with every disease known to man so I will become super immune oh yeah. It's big brain time.

  31. Dear Pro-Vaxxers, can we agree that injecting mercury (ethyl-mercury from thimerosal in vaccines, a neurotoxin) into a baby under the age of one is a bad idea?

  32. I’m really tryna find the triggered antivax Karen in the comments but all I see is alive and well, vaccinated people

  33. see, one year ago, i choked because i drank some water, could this be coincidental? that moment i was so scared, but later on i forgot about it
    but three months ago, my son choked and coughed because he drank water and died.
    i was desperate, i found out that is was not the only one on the internet. each year, tons of people choke to death drinking water.
    i now am a proud supporter of anti water club. we suggest that u should not drink water because you might choke to death as a side effect.
    so join us in our fight to defeat water, it does nothing but to kill, u can start by showing an example to people around u, STOP DRINKING WATER.

  34. Why isn't mercury and other heavy metals in vaccines mentioned?…or are those only going into state insured, poor kids, so nobody cares??

  35. The fact that this video was sponsored by Bill Gates doesn't make it sketchy at all (sarcasm). Vaccines are part of their depopulation agenda and contain RFID chips….we'll see who's safe when all the 5G towers are up and running. 😉
