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.

    it seems the worst side affects of vaccines are actually symptoms the disease would cause worse forms of had the child not been vaccinated. Also, autism is not the worst thing that can happen. The quality of life of an autistic person is great (I actually have it). Actually, it seems some diseases have gotten stronger because people have not been vaccinating so they are more lethal because they had more "leash".

                  its funny how a lot of anti vaxxer kids will immediately get vaccinated once they become an adult, its sad the children know better than their own parents

                                        In the future could you do something similar for vitamins/supplements? A lot of doctors say they have nothing in them because they are unregulated, and then turn around an tell you, you need more of [X] and recommend you take an over the counter vitamin/supplement. It just feels shady, and I don't know what information to believe with all the miss information out there.

                                          I'm still staying with the conclusion that even if vaccines do cause autism, I'd rather be autistic than, you know, dead.

                                                  If we'll make it stronger it can damage the body more than it should
                                                  And while the immune system recharges more diseases attack making it more serious
                                                  If we use weaker diseases we can make the memory cells remember how they removed the disease

                                                                    It is true that more vaccinated kids develop autism
                                                                    Because symptoms of autism start showing up most often after 3 years of age, and vaccinated children are more likely to live that long.
                                                                    Idk if dis is true, but is a funny joke
