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

  • Published: 12 May 2019

    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.

      I'm sorry, but we are the sickest species ON THE PLANET. Just think about that for ONE minute.
      Our gut microbiome is being sterilized by pesticides like round up, and we are told they are safe(yes, they kill the bacteria in your gut - shocker), but DON'T WORRY, they have something you can buy for that.

      We are developing autoimmune diseases left and right. A study was just released that shows how millennials health plummets at around age 27, and no one is concerned that it's something to do with out healthcare? "healthcare" - that's a misnomer at this point.

      The SAME people that push round-up as being safe(now proven to cause cancer in a court of law), "provide" us with cancer treatments and vaccines.

      The same people who sell us vaccines, treat our children of these chronic illnesses. NO ONE is brave enough(or intelligent enough) to raise an eyebrow to that?

      Oh, wait, they are, but then they are told they are just crazy conspiracy theorists who are probably literally hitler and voted for trump. And people fall for it because it makes them FEEL safe. Meanwhile over FIFTY PERCENT of our youth(YOUTH!) have chronic illnesses that the AMA says they will NEVER recover from. And it's not enough for these mega corps to make millions or billions, now they are pushing for trillions.

      That's not fishy to you guys?

      I swear, people have thrown common sense directly out of the nearest window for, "double blind published data" We will NEVER get it. There are too many variables involved and you know this, that's why you keep asking.

      Honestly it makes me sick and people who are working for them should be ashamed of themselves. They aren't, because they have money in the bank, but one day, people are going to have had enough and they will be found and prosecuted.

      How many more of our loved ones have to suffer and die before it gets to that point?

      thank you for making this video, its been a great help for my social justice project. I hope to use this as a source to help write my letter to a politician, (who is undecided as of writing this), I really hope to make a change and to make vaccinations more mandatory in the united states!

                                                              The idiocy in this comments section is absolutely staggering. You guys REALLY think this video is educational? I bet you think Bill Nye and Myth Busters are just peachy and have an "I fucking love science" t-shirt, dontcha? You know what feels even better than acting like you're smart? Actually doing your research and knowing what you're talking about.
                                                              But you know what's easier than thinking for yourself? Letting other people think for you. Then you make "savage" comments about people who dare to disagree, while projecting your stupidity onto them(by calling them stupid).
                                                              Hell, most of you haven't even been able to read long enough to make it to the end of this comment. TL;DR! LOL! But if you have, I'll commend you and ask you not to believe me. DO your own research and particularly, look into the work of Dr. Shoenfeld. His resume and qualifications are so extensive that I can't even post it all without copy/pasting, and that gets my comments deleted. He's dedicated his entire life to studying autoimmune diseases. He says vaccines are causing them when you have the right genetics for it. That's why not everyone gets them. He has videos on youtube. You can read his qualifications there(one being the HEAD CHAIR of medicine at TEL AVIV university(the most prestigious university in Israel and top ten in the world outside of the US). Over 1600 published papers and he's been cited by professionals over 20,000 times. He's no quack. Look into it. Or keep letting other people think for you and hope you never lose a loved one to chronic illness that you could have stopped if you weren't so damn lazy/distracted/willfully ignorant.

                                                                At least one of you took the time to look into it. If you don't agree with it, then that's your descision.

If anyone takes your word over one of the TOP MEN IN THE ENTIRE WORLD, then they're fools and I really feel sorry for them. Not tritely, but I honestly feel bad for them because they're gonna suffer in life.
