    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.

      It would be nice if you had touched upon, or at least mentioned that we vaccinate against a multitude of other diseases besides measles.

          Me and all my siblings have matching scars from when we got vaccinated against swine flu as kids; the injection point became infected and there was a terrible wound with tons of pus and it left a nasty scar.

                anti vaxers are retards like if u agree they are looking at the wrong side , at the 0.01% risk vs the other good side . they are literally killing their children or putting them at risk of death

                        This video is pinned on one vaccine BUT there are hundreds? of vaccines. So what I wanted to hear was there are rankings of vaccines (we are dealing with parameters). Some countries just can't afford all vaccines and all the time BECAUSE other budget amounts will dwindle. So, the formula and decision making is more than what this video has covered.

                          I liked the video however I noticed you guys were really uncomfortable to say that in extremely rare occasions vaccines do appear to kill children. We really shouldn't shy away from naming those things as it would allow a better comparison with the number of children killed in the non-vaccine scenario.

                                  A child just contracted polio in both legs after taking the polio vaccine, he has healthy before taking the vaccine. India is not polio free for sure.

                                                        Yes. Because I'm going to believe the very same government who's been sterilizing women without their knowledge in Africa for the past 30 years through vaccines. The very same government who purposely makes people sick so they can make more money on our illness. I love America, but I don't trust the government and I don't trust the CDC. They would rather us be sick. They inject you with at least 5 different things 30 seconds after you're born. These vaccines have mercury in them. You're not supposed to eat salmon because it contains mercury, which according to the exact same governing body will cause a slew of health problems... but it's okay to inject MERCURY in your bloodstream where crosses the blood-brain barrier? A pregnant woman isn't supposed to eat sushi because of the Mercury, but it's okay for her to get mercury in her bloodstream. It's okay to give a newborn baby up to 60 different shots of mercury before it's 3 years old? No. I'm an anti vaxxer I will not vaccinate my children unless I absolutely need to and I will take each and every single vaccine into Deep consideration about my local situation at that time. If there's an actual need for it I will weigh the risk of my child and all the shit that's going to be injected into my child. I'm not going to not vaccinate my all the shit that's going to be injected into my child. I'm not going to not vaccinate my kids Purely out of stubbornness. I will take everything into consideration. But they will not be vaccinated for certain things at all. Ever. The flu? No. Chickenpox? No. but there will be things I will consider depending on where I live at the time

I still get myself vaccinated even though I almost faint and sometimes barf when i get the shots. Please, anti-vaxers (and everyone), get vaccinated to make the world a better place.

It's like playing Russian roulette with your child's health.

One day prior to 9/11/01 Donald Rumsfeld announced that the pentagon was missing 2.3 trillion dollars from their books. He said they were going to do an investigation. Today the US total debt is almost 74 trillion dollars. Out of that debt as of Dec. of 2018, 21 trillion is missing from their books.

Think of what an awesome product they have: something everyone believes you ought to have, billions of customers, often mandated by governments.


                                                                                        Have you ever looked at the ingredients of a vaccine? I have, and it generally contains three items:
                                                                                        1. vitamins, minerals and amino acids. Great.
                                                                                        2. deactivated disease. Necessary.
                                                                                        3. Formaldehyde. A known carcinogen.

When you are younger you usually need more than one periodically because your immune system builds on itself over time. Now if you cant split a couple of necessary bucks for your child, that means you probably shouldn't have had a child in the first place. Look, I can see your concern otherwise about big companies being greedy, (that is true) but there isn't too much you can do at an immediate time other than vaccinate your child! Not just for the safety of your own child, but also for everyone else's children!
