    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.

    I really love that they used the MCUs mutilverse number ID and snuck in the Avengers Tower and helicarrier in there. 👌 although if this is a time before Stark dies no way would it be a world where they stop vaccination.

                        Google is full of misinformation, cynics, myths and all . There is always benefits and side effects of everything but this video nicely enlightens that how to be rightly informed and assess that benefits over the minuscule of side effects . So we people need to be more logical rather than being always critics and cynical. Great video and the eye opener for the many.

                              Im an anti vaxxer! Please crucify me with your hive mind and repetitive jokes.

                              My arguement... it shouldnt be the fucking law to accept a "practice" (which is what medicine is. Its not a fucking science.)

                              The government doesnt have the right to tell you what to put in your body. Thats the fucking arguement. Not whether they work or not. Its the fucking right to be able to choose what goes in your body and your kids. Your allowed to have your OWN ideas and beliefs. You all are probably the same idiots that think the sun has nothing to do with climate change. I bet none of you even know what solar forcing is. Anyways...

                              Please be as rough as you like. 😈

                                                  Is the decline in measles in the developed world largely due to vaccines or improved sanitation and nutrition? Do any of the studies showing no link between vaccines and autism study the effect of multiple vaccinations in a relatively short time (i.e. what happens in real life)?

                                                    Seeing that measles cases plummeted to below 100 per year after MMR was introduced, I'm pretty sure it was MMR.

                                                      @Vary Olla amazing the lengths people will go to, to justify their decision to not weigh evidence. Are you the reason that character assassination works, or are you the intended victim? I'd tell to draw your own conclusions, only clearly you've not you the background to do so. Watch the video, since you clearly know nothing of what's in it!?!?!?!!!

                                                      Vaxxed = pseudo-scientific "documentary" created by known anti-vaxxers with a history of misrepresentation of the science.  Wakefield was drummed out of the medical field for making dubious claims about vaccines and autism and then seeking to potentially profit from those claims. 

                                                      Meanwhile it was produced by an individual who also runs an anti-vaxxer group which has as it's president an individual who likewise represents a Foundation which funds anti-vaccine claims.  Meanwhile people in the video such as Hooker represent known anti-vaxxer "researchers" who for years have perpetuated dubious pseudo-scientific claims about vaccines.  These people are likewise affiliated with anti-vaccine groups who often fund their supposed "research" and in the case of Hooker have had papers retracted for questionable methodology to arrive at their supposed conclusions.

                                                      Moral of the story:  I have no need to watch a video which emanates from known discredited people and which merely parrots pseudo-scientific claims which the anti-vaccine industry - and yes it is indeed an industry by the way - has perpetuated for years now as I am all too familiar as you see with what those claims represent.  As the old saying goes:  _"garbage in ---------> garbage out."_  You need to find more credible sources of information I'm afraid.  Have a nice day.

                                                      @Vary Olla thank you for your comments. Can you clarify whether you have in fact watched Vaxxed?

                                                      _"watch the case made by the opposition, and draw _*_your own_*_ conclusions."_  = source of all your deductive fallacies Omer.

                                                      There is no "your own conclusions".  There is only real science = and then there is pseudo-scientific claims which most often reflect an underlying ideological bias towards vaccination in general.  So you apparently believe - as others often do - that your "opinion" is what matters = afraid not.  What people choose to believe or not in truth matters little as people frequently can and do convince themselves of all kinds of silliness - most often as a result of ignorance of the topic at hand. 

                                                      If you do not understand the science = you will be unable to discern between what is credible and what represents facile dubious assertions.  So in actuality the anti-vaccination movement is a good example of Dunning-Kruger Effect.  It's minions mistakenly believe they understand the science behind vaccination - when they so clearly do not - and it is that ignorance which prevents them from forming correct deductions about it.  That condemns them to a vicious cycle of poor deductions which ultimately feed back upon themselves. 

                                                      Moral of the story:  belief is easy...................proof on the other hand is difficult.  So it's not what you believe that matters = only what credible evidence if any is behind said belief.  The supposed "evidence" the anti-vaxxers regurgitate online along with their mundane conspiracy theory rationalizations are nonsense I'm afraid.  Have a nice day.

It's well scripted and slick, and you can only tell the inordinate bias if you happen to have seen the case made by the opposition, a case that's not mentioned here or very much anywhere. The video functions like a part of an extremely effective disinformation campaign - and who has both money and motive to carry it out, but for a pharmaceutical firm?
