    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.

      vaccines are not subject to the safety rigors undergone by other pharmaceuticals in the FDA approval process. There are no large scale, double-blind, placebo controlled studies. And, in the one 1930 human study of thimerosal that predated its use in vaccines, all the subjects injected with thimerosal died. In 2004, an FDA official acknowledged in testimony before a Congressional committee, that no government or privately funded study has ever demonstrated thimerosal’s safety. On the other hand, there is plenty of science suggesting that thimerosal is NOT safe. Several hundred studies available on PubMed link thimerosal exposure to the neurodevelopmental and immune system diseases that are now epidemic in the generation of American children born after the CDC dramatically increased childhood thimerosal exposure starting in 1988. My book, Thimerosal— Let the Science Speak, summarizes these studies. The scientific literature inculpates increased thimerosal exposure as a culprit in the explosion of ADD, ADHD, speech delay, narcolepsy, SIDS, ASD, seizure disorder, tics and anaphylaxis, including asthma and food allergies. According to the CDC, one in six American children—the so called “thimerosal generation”—now suffers from a developmental disability. We have published a compendium of 80 published, peer-reviewed studies that strongly suggest a link between thimerosal exposure and autism.

      I'm sorry, but we are the sickest species ON THE PLANET. Just think about that for ONE minute.
      Our gut microbiome is being sterilized by pesticides like round up, and we are told they are safe(yes, they kill the bacteria in your gut - shocker), but DON'T WORRY, they have something you can buy for that.

      We are developing autoimmune diseases left and right. A study was just released that shows how millennials health plummets at around age 27, and no one is concerned that it's something to do with out healthcare? "healthcare" - that's a misnomer at this point.

      The SAME people that push round-up as being safe(now proven to cause cancer in a court of law), "provide" us with cancer treatments and vaccines.

      The same people who sell us vaccines, treat our children of these chronic illnesses. NO ONE is brave enough(or intelligent enough) to raise an eyebrow to that?

      Oh, wait, they are, but then they are told they are just crazy conspiracy theorists who are probably literally hitler and voted for trump. And people fall for it because it makes them FEEL safe. Meanwhile over FIFTY PERCENT of our youth(YOUTH!) have chronic illnesses that the AMA says they will NEVER recover from. And it's not enough for these mega corps to make millions or billions, now they are pushing for trillions.

      That's not fishy to you guys?

      I swear, people have thrown common sense directly out of the nearest window for, "double blind published data" We will NEVER get it. There are too many variables involved and you know this, that's why you keep asking.

      Honestly it makes me sick and people who are working for them should be ashamed of themselves. They aren't, because they have money in the bank, but one day, people are going to have had enough and they will be found and prosecuted.

      How many more of our loved ones have to suffer and die before it gets to that point?

                    A) Thank you for making this video! Even though we know that vaccines are important to stay alive, but it’s good to recognize how vaccines work, and why they’re so useful. And B) wouldn’t it still technically be your body getting stronger if you don’t die? Your body creates memory cells, which makes your immune system stronger against diseases. Though, if I’m wrong, my sincerest apologies, I’m just curious.

                                        I remember a few years ago, there was a commercial airing on TV about Whooping Cough. The first time I saw it, my only thought was 'Whooping Cough? Who the fuck gets Whooping Cough?! I thought we all but eradicated that!" It's really sad that this anti-vaccination BS is bringing back diseases that had been practically unheard of for generations.

                                          You got it!  Once upon a time many infectious diseases were "endemic" = meaning that outbreaks were self-sustaining and thus they were ubiquitous across the land.  Then as a result of mass vaccination programs = over a period of years we saw massive reductions in incidence as the cumulative herd immunity built up.  Net result: few people alive today have ever seen a case of many of these things.

                                          Unfortunately as the old saying goes:  _"history repeats itself."_  This happens because subsequent generations forget the hard-fought lessons of previous ones.  So the young people today who represent many of the anti-vaxxers = grew up in a world where things like whooping cough were basically nonexistent.  That made the concept of infectious disease prevention abstract in their minds as they had never seen a case = and accordingly they incorrectly believe that vaccines are unnecessary.

                                          So the moral to the tale is that you do not live in a vacuum.  Infectious disease pathogens exist in nature - and thus in human populations.  Accordingly you are always at risk.  We can then either mitigate that risk via vaccinations = or suffer the results of the breakdown of that herd immunity which took decades to build up............and once again these things will rear their ugly heads.  Have a nice day.

Human life has improved a lot since Science and progress took over, so many people have bleed in order to achieve what we have right now. So, please, someone explain to me: Why are these idiots insulting our doctors, our historical memory and their own intelligence?

                                                  It must have something to do with narcissism: since the actual knowledge doesn´t register properly in their brains, instead of making the effort to learn, they choose to follow a shortpath to "knowledge" so they'd feel better with themselves?
