    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?

    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 isn't the idea of vaccination that is the problem, it's what else is in the vaccine. There have been too much correlation between getting vaccinated and lifelong problems (including autism), to just drink the Kool-aid without asking questions. Now a days, they give babies way too many vaccines before their immune system can develop (which is at age 2), and their immune systems remain forever messed up by giving them that many shots at such a young age. To NOT have reservations about vaccinations at this point has me confused.

                    This video is missing some more research. Im all for vaccines, but no deaths caused by vaccines? Many times the hospitals say that it was a coincidence, and then they dont really put it on the system, and the cause of the death ends up being an "accident". Really, this video is literally saying vaccines are 100% good and everyone should take every vaccine that exists. I think people need to be more critical of what they believe and take, because they can be themselves being manipulated by big pharma. Vaccines is not ALWAYS good. I support vaccines, but I dont support the excessive use of them. Just my opinion tho

                                        The best thing is that we already vaccinate most people and almost no one has got a serious disease in their lives. Even some people think that we shouldn't vaccinate. We don't need a gedankenexperiment, we already are in that state of almost nobody getting serious symptoms.

                                              I keep reading the argument is not that vaccines are bad, but bad vaccines are bad. The argument says that nobody disputes that vaccination theory works, but their dispute is not all vaccines for the same disease are created equal, like a car with a 5-star crash rating vs a 1-star one. Vaccine manufacturers maybe are adding too much to their products, and are forcing the little ones' immune systems to handle too much at the same time. So, the argument says, do vaccinate your kids but give their little bodies plenty of time for recovery between doses, and ask your government to keep an eye on the manufacturers.

                                                "handle too much" is bullshit and anyone who thinks that 8s seriously retarded. The human body encounters tens of thousands of different types of pathogens daily. Vaccines, in this context, are less than a drop in a bucket. A bucket the size of mount everest.

                                                  You know what's weird? I was not vaccinated (often anyways, skipped appointments or whatnot) when I was a kid except for when i was born and stuff (around 2 years i guess we forgot? I'm not quite sure) and I have to say, I was probably saved by herd immunity. quite literally. I was never anti-vaxx to begin with, but we just... never focused on it. I just never got sick anyways. Thanks for the information kurz!

                                                  Besides, we do not have to worry about anti-vaxx people for long, hopefully none of them get lucky on living. I don't even want them to die, its just they are too ignorant to be on this planet for long. It's probably that or they are parents who got stuck with kids they didn't want and, even knowing the facts but not listening because they're trying to act ignorant and have no heart, want to get rid of them in some creative and cruel murder. Its terrible, absolute shame to anyone out there who seriously avoids stuff like this (nice clickbait btw) and get mad when facts are hitting them hard.

One thing that stuck with me more though, was the ability to have empathy, but that took a while, it was hard getting past the anger at a person who shot up, or wrecked their car drunk with no seat belts on their kids. What I am trying to say (ramble on about) is that even though I am 100% pro-vax , I think many anti-vaxers truly think they're fighting the good fight, and as much as I love seeing a stubborn one put in their place, maybe we need to approach them with some empathy and life experience before calling them baby killers. So to you, Mr or Mrs. anti-vaxer, I get it, you don't want anyone telling you what you can and can't do when it comes to your child, politically I'm not a fan of big govt telling me what to do either. You have to realize though, this isn't the same thing, this is a life and death issue, that can directly effect yours and other peoples children. That is why we do let the government tell us that we can't murder people, we let them tell us how fast we're supposed to drive on roadways, we even let them tell our children how late they can be out at night. If you truly care about your children, then try this... find 2 medical professionals with advanced degrees in your state, that agree with not vaccinating children, and that vaccines are more dangerous than the alternative. While your looking, ask each of those professionals that don't agree with you, their true, or off the record reason for believing in vaccinations, and write them down or record them, you will get some wonderful, truthful and knowledgeable answers, from real people in the medical field, out there in the real world, not just the "medical community" that so many anti-vaxers dismiss as part of the conspiracy. Let us know what you find out.

I could be wrong though, I've got no evidence :/

But in the theoretical experiment with vaccinated kids words like "might" implying there is a small chance was used when talking about the negative side effects. Yes, there is a small chance but implying there is a small chance to the small chance doesn't seem right like if a statistic was to say 9 out of 10 of you will grow a beard by the age of 21 but pizza lowers the chance to 1 out of 10 grew a beard by age 21 and for me to be doing a theoretical experiment out of 100peoplke what he said would be the equivalent of me saying 90 people would've grown a beard by age 21 without pizza but with pizza only 10 people might've grown a beard by age 21. you cant Imply probability in one case and certainty in another I'm not against vaccinations I think they're fascinating and necessary to the growth of our planet but I can sense a bias in your diction
