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.

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

                                        How is "tricking" the body a beautiful mechanism? What about the dangerous ingredients such as mercury that are added to the vaccines? Building something weak to shoot into the body does not sound beautiful to me.

                                          mercury has been removed from vaccines, and even when it was still in them it was in minuscule amounts that would cause no problems

                                        Thank you, Kurzgesagt. Sadly, I don't think that even your simple to understand explanations will be enough to educate our population of anti-vaxxers... We appreciate your efforts, though!

This may be a coincidence, but at 4:54 the top left is labeled "Earth #199999", which is the original universe number assigned to the Marvel Cinematic Universe. And, at the same time, the top right has an airship that resembles the Helicarrier. I don't know if this was intentional, but it's a cool easter egg if so.

                                                                            Edit: This was definitely intentional, I just noticed that Stark/Avengers Tower is in the center of the large city. Way to go guys!
