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.

                  My favorite pro vaccine joke:
                  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

                                      Vaccines won’t be available forever. If we can eradicate those diseases NOW, we need to do it. Sooner or later those pathogens will evolve. Only those pathogens who make it difficult for us to make a vaccine for them will survive if our attempts are half-heated, and they will lead to a new generation of vaccine-resistant (hard to make vaccines out of) diseases of which we will have no effective counter. Thus far, we have only managed to successfully exterminate smallpox in the century we have had vaccines for. Our time is running out...

                                        why do you think vaccines won't be available forever? also, we've almost beaten polio, and measles won't be far behind. unless antivaxxers, of course.

                                          If your kid dies from measles you only have yourself to blame

                                              +suicine94 Your spelling and grammar is as atrocious as your information. There have been RECENT cases of kids dying from measles, so we know that the disease isn't extinct.

                                              You're not a doctor or an archeologist by the sounds of it but rather just some fool who goes on the internet believing in whatever conspiracy theory they see. There's only a single paper that supports your view and it's been debunked by several others that actually use scientific logic and statistics. And 10 of the 13 authors of the vaccines-cause-autism myth actually admitted to falsifying the evidence in that paper (the other three are probably dead because they believed their own lie).

                                              There are so many diseases in the world because microorganisms are constantly evolving. You should be grateful that you live in a generation where you can prevent the spread of diseases that couldn't be years ago.

                                              Jesus, whenever an anti vaxxer tries to argue their point they just sound like some kid who still refuses to wash their hands.

                                              How coincidental that polio disappeared after its vaccine was developed.
