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

    Vaccines are one of our best tools to prevent dangerous diseases, but they come with side effects. So would it be safer not to vaccinate?

  • Kurzgesagt – In a Nutshell

    Dive into sources and further reading here:

    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.

    You want to ban something?

    Ban cars

    Car accidents are one of the biggest causes of death in the world, all for the sake of getting places faster

    instead of cars, a country could invest in public transport (like trains) which are not only safer, but more ecologically friendly and efficient, and then reserve cars as being something to use outside of the main infrastructure (like when driving to and in less populated, or otherwise underdeveloped areas like...say a mountain!)

    Not to mention that reducing the number of cars on the road by stipulating a specific use for them would also reduce the actual danger of car accidents, since with less drivers at any given time the chance of an accident plummets

    The ability to arrive at different places quickly is also growing less and less relevant as our modern world becomes more and more digital, it would be relatively easy to minimize the commute time by focusing more on the virtual aspect of life (something that is already being done to an extent) which would inherently reduce the need for quick, widely available transportation, the main obstacle stopping this from happening being that human beings don't deal well with sudden changes, so it must be done gradually, alongside older folks who refuse to accept change by sheer stubbornness.

    Of course that point brings up the argument of human interaction online VS human interaction in person, which I won't touch since it's hardly something I can definitively say I'm on the right side of (as it's mostly a matter of personal opinion at that point, and anything that isn't opinion-based is beyond my knowledge either way)

    Or caffeine, one of the most widely used ADDICTIVE and HARMFUL chemical substances, which goes almost completely unregulated because even those in charge are either hooked or well aware of the massive backlash that taking action again caffeine would create.

    In short, instead of worrying over babadooks and boogeymen, look at the big, rational and REAL problems modern society has and take a stand on those, if you have the will to change the world for the better, at least try to actually change it for the BETTER and not plunge us back into Medieval times.

  • Szymon Wydymus

    Yeah. But you don't mention new vaccines, whitch pharmacological companies want to sell in countries to increase there income. By making this video you want to make vaccines more socially acceptable, and i hope it wont turn bad for You if one day those companies forget about what vaccines are used for and they start to make profits from them. In that case vaccines can contain a lot of not tested components and people will be "experimental rabbits". Good for companies because they will have more and more new customers if there will be some complications. VACCINES CAN BE GOOD, but CAPITALISM MAKES PEOPLES (minds) SICK.

  • Matt The Wildcat

    My mom thinks that vaccines are extremely dangerous because my brother and I always get fevers after every single vaccine and I get the bonus of a little rash that last like... one to three days. She thinks that every kid gets these reactions and that many die.
    I also have Aspergers but luckily, she connects that to some Christian thing and not vaccines.
    Also, I’m not Christian. I’m just a weird kid who believes in the craziness that is mythical spirituality. I think it’s kinda stupid but I still believe in it because I’ve been left no choice due to the fucking omens and shit. Even when I don’t get some sort of prophecy, there’s still the fact that I never get deja vu, instead, I relive moment from my dreams. So................. how else am I supposed to not only explain that, but also the fact that I started believing in it the same way everyone else did? (Which would be simply because it felt right before we even knew it was an actual belief)

The only exception is when you fall, hit your head or have an accident. Wait 4 -5 day. Take it easy after an adjustment.

    I remember when I was little, I had to get a live vaccine shot, then a few weeks or months later (barely remember) they came out with a nasal vaccine and I was so excited to get it with my family, but that was also a live vaccine, and I was still in the 'recovery' time for the first vaccine so instead of the nasal spray they had to prick me again with a needle for the vaccine and I was so bitter about it for weeks

    Shame on you for making this. Time for you to sit down with one of the thousands of parents whose child was broken and changed overnight after an injection.
    I ask you this: why don’t you make a research video on FLOURIDE FORCED INTO EVERY WATER SUPPLY. How every man woman and child’s pineal gland is rock solid from fluoridation. Research into that and you will start to see what’s going on.

    • ElectroLuxray _

      Zac Mead why don’t you sit down with one of the millions of parents who had a child DIE form a preventable disease or have gotten severely injured. Also, the amount of fluoride in water isn’t dangerous, because it’s not the thing itself that is the poison, it’s the amount. Water can be lethal if you drink enough of it. You probably consume small amounts of fluoride from your toothpaste every day.

      Kids who have suffered the (extremely unlikely) side effects of vaccines are just the unlucky ones who shouldn't be vaccinated, but are protected by herd immunity (everyone else being vaccinated). Their parents should be the biggest advocates for vaccines if they want to keep their child safe.
      If you can't be vaccinated that's a shame, but everyone else SHOULD! Otherwise everyone will start dying from all kinds of illnesses again like in the 1400s

    I sense a prisoners dilemma calculation... it's (very very *very* slightly) advantageous for a single person to defect and refuse vaccination, relying on herd immunity to give the benefits of vaccination to them personally, while avoiding the risk of side effects. But when *everyone* does that (or, 5% of people do that) this calculation breaks down, and everyone loses.

  • Typrus
    Typrus Day ago +4

    Here's how I see it. Vaccines have risks. Ok, what do I mean and what is to be done?
    My nephew had a reaction to a combination of vaccines that resulted in a high fever that has had long term effects on his speech. "Oh no!" I hear you say. Well, yes it's unfortunate- so what has my sister done about it? Has she become an ardent anti-vaxxer? No. Well what about me? My daughter had a bad reaction to a combination of vaccines that resulted in high fever, febrile seizures, and nasty rashes. Am I an ardent anti-vaxxer? No.
    What both my sister and I did is to have frank, honest, and open discussions with our children's pediatricians. We developed a strategy, a little different in each my nephew and daughters cases, to get them their needed vaccines, but staggered out.
    Both my daughter and my nephew (not to mention my son, other nephew and 3 nieces from the sister in question) are up to date on their vaccines. We developed a staggered and delayed strategy to get them what they needed while considering the risks and individual concerns.
    What about autism??? Well, both my daughter and nephew have ADHD- the real deal not some hyper-diagnosis hoopla. "Ah-hah! The smoking gun!" No. Again, no. My grandfather, uncle, father, 2 of my sisters, and myself have diagnosed REAL ADHD. We have genetic predisposition for certain neuro-atypical characteristics.
    We need to approach vaccines, like many other things, with respect and healthy caution- not blind fear and ignorance. Is there risk? Yes. Are there ways to deal with the overwhelming majority of those risks? Yes.
