  • 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.

                            Where I was born vaccinations aren’t the parents choice and that’s how diseases and viruses such as influenza and measles can’t make a comeback there.

                                          Aren't people born with autism? So even if vaccines do cause autism, it would be appear in children, not vaccinated people. Not to mention by that time vaccine is long gone meaning it was our overprotected body that caused the autism.

                                              Since we are over populated we should say thanks to those who wants to die fast . What the issue here I don’t understand. You profixers are all protected . Let people scarified there life’s and reduce global warning . Why you suckers so desperate here ? Are you worry about those few immuno compromised child ? Who need natures mistakes anyway ? Spartans feed birds with nature’s mistakes . Let people die and save the world . Or you feel that you were fooled ? Or you understood that you have been damaged ? And now envy to those who are smarter , healthier ?

                                                For others do not invest in long term real estate- there will be no value in the future. An abundance of housing coming.

How can people say vaccines are bad . Crazy. But I’m Orthodox Jew so we are exempt from vaccination. So sad that we can’t join to benefit mankind .

                                                              Vaccines are medicines, and as all medicines, there is a need to consider children by case. In Italy they do not do that. We have more than 10 mandatory vaccines, and some of them are done together (3 vaccines at the same time), and this is dangerous. Who does say so? The books of medicine! They say something but they do the opposite.

                                                                No = it's not.  From the very moment an infant is born = it is exposed to a myriad of microorganisms.  You have right now a host of bacteria, viruses, and fungi living inside you and which wage a continual war against yourself and each other. 

                                                                So not all vaccines are the same as some contain entire weakened pathogens - while others only contain pieces of a pathogen or else the toxin it produces.  A piece of something - let along a toxin - can not replicate and thus it is impossible to infect the individual with the condition.  Meanwhile the employment of attenuated pathogens is tolerated by almost everyone.  We can sometimes see - albeit very rarely - a few who owing to some idiopathic issue with their immune system they have trouble destroying the weakened virus. 

                                                                So a person who can not even tolerate exposure to a weakened virus = will in all likelihood react similarly - or worse - upon exposure to the full-strength "wild" version of the same.  If you want to critique vaccine employment you'd better look at the entire picture and get your facts straight first.  Have a nice day.

                                                              people are concerned that if vaccines were mandated by the government, that opens the precedent that your personal health care is no longer private, meaning that opens pandora's box for forced abortions, or something more realistic like micro-chipping citizens. The liability of the government for a bad batch of vaccines, or the fact the government could maliciously alter a vaccine after they are mandated is a privacy and health concern. Vaccines are good, but they shouldn't be mandated.

Literally anything can be a toxin if in a high enough dose, but the dose of Mercury in vaccines beforehand was so minimal, that a singular bite of salmon has 100x the amount of Mercury in it. It was used as a preservative to make sure that the vaccine didn't expire quickly, which nowadays vaccines expire much quicker due to the removal of Mercury.
