    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: https://sites.google.com/view/sources-vaccines


    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!

        Please vaccinate your children for the life of the child

                                  So, the one study that found the link, when it wasn't even trying to do so, has been disputed? Hardly.

                                  You also never mentioned any of the deadly chemicals in vaccines. Formaldehyde, Aluminum, Mercury, and several dozen others.

                                  Natural immunity will always trump artificial immunity.

                                  A few years ago, the measles outbreak in the eastern US, was made up entirely of pre-inoculated individuals.

                                  Your bacteriophage video is also a strong argument against vaccines. Just saying.

                                    +MQF II omg!! Did you know that dihydrogen monoxide is ingested by billions of people around the world daily! The fda still hasn't banned it's use despite it being one of the major substances causing rust in metals. This sort of government conduct with no consideration for ordinary civilians such as myself simply disgusts me.

                                    Please Create a video related to solar energy
                                    Some solution is required for it
                                    Such abundance yet negligible amount utilised! Its crazy!
                                    I feel priority should be given to efficient usage of solar energy
                                    Once we solve this problem
                                    Our earth may sustain for some time while we can explore more
                                    And whats the dark reason behind not using it? Is it just uneven distribution of such energy? Lack of technology? Lack of infrastructure and funding? Or is it the economy and status quo?
                                    Though If we succeed in harnessing solar energy, will it be a boon or curse? How?

Not to mention by that time vaccine is long gone meaning it was our overprotected body that caused the autism.

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 ?
