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.

                        Really crazy how vaccines are used by the government to control the masses but you retards think “hahaha anti vaxx child die in 2 years Karen funny anti vaxx meme” is what you should focus on. Brain dead.

                                    I love the way the video is titled. It's titled in such a way that anti-vaxxers are most likely to watch it.

                                    Of course it's for lol, but it presented in such a way that you should logically reach the conclusion that vaccines are good, instead of just saying "vaccines are good lol".

                                              This video summarises the details and risks of vaccines very well, it also shows how they can help people who can't be vaccinated. But I can imagine how angry an anti-vaxer would get at seeing their 'reasoning' be challenged so heavily that they literally collapse to the floor as their dorment polio sets in.

                                                My best argument to antivaxers is that their rationale about not getting vaccines removes any chance of getting any side effects, is like someone opting to NEVER leave your home, so that you can't be run over by a car. Same with too much drinking water can lead to death. So you opt to not drink water? antivaxers are like a disease and they talk and they spread their "wisdom" like flat-earthers do. Except flat-earthers don't hurt anyone. Antivaxers give hope to diseases to come back from the dead.
