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.

      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!

      It would be nice if you had touched upon, or at least mentioned that we vaccinate against a multitude of other diseases besides measles.

                    Only those worthy to know receive. The pro-disease always try to pull it out, different methods, but never try a direct approach. But if they were given the knowledge to pull it out directly, they refuse to do so

                                            So, the one study that found the link, when it wasn't even trying to do so, has been disputed? Hardly.

                                            You also never mentioned any of the deadly chemicals in vaccines. Formaldehyde, Aluminum, Mercury, and several dozen others.

                                            Natural immunity will always trump artificial immunity.

                                            A few years ago, the measles outbreak in the eastern US, was made up entirely of pre-inoculated individuals.

                                            Your bacteriophage video is also a strong argument against vaccines. Just saying.

                                              The amounts of toxic elements and chemicals are very small - there is no evidence to say that they are lethal.

                                              And let's accept the argument that natural immunity always trumps artificial immunity (I have never seen anything like this, but for arguments sake I will assume it does). The cost of said natural immunity is many lives (many more than what will die as as a result of injection of vaccine related cockups). Are you really willing to kill people because you believe it's slightly more effective

                                              Please Create a video related to solar energy
                                              Some solution is required for it
                                              Such abundance yet negligible amount utilised! Its crazy!
                                              I feel priority should be given to efficient usage of solar energy
                                              Once we solve this problem
                                              Our earth may sustain for some time while we can explore more
                                              And whats the dark reason behind not using it? Is it just uneven distribution of such energy? Lack of technology? Lack of infrastructure and funding? Or is it the economy and status quo?
                                              Though If we succeed in harnessing solar energy, will it be a boon or curse? How?
