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: 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?

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.

I will never understand why people believe that their amount of hours spent in Google are more valuable than the several years their doctors spent at the university. 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? Boh. At least both the video and your comments are awesome. Thank you! XD¡

Just a curiosity, if we get immunization from getting sick, why do I need to get booster shots every year/ couple of years?
Vary Olla
Vary Olla Day ago
As Richard noted there are different reasons. Sometimes as noted the pathogen mutates. Also it depends on the type of vaccine. As an example the Tetanus vaccine is what is known as a toxoid vaccine. That is because Tetanus is caused by a bacteria which releases a toxin into your bloodstream = and it is the toxin that causes cellular damage. So the vaccine imparts temporary immunity against the toxin - but you must get booster shots every 10 years as that immunity wanes for your average person after 10-20 years. It also can depend upon how "strong" your body reacts to the antigen. As an example. The Pertussis bacteria is a nasty one which can trigger a harsh reaction in the body. So the old Pertussis vaccine was what is referred to as "whole cell" = meaning it used the entire bacteria. Accordingly it also used to sometimes trigger harsh side effects in susceptible people - although it generally imparted good immunity response. Some years back however we saw the development of an "acellular" Pertussis vaccine - or recombinant DNA technology. Now a "piece" of something can still trigger immunity while not resulting in as harsh side effects = making it better tolerated by all. The downside however if you will is that the immunity it precipitated does not necessarily last as long as the older whole cell vaccine version. So vaccination science is as much a "tradeoff" as it is about science. Some pathogens are harsher on the body than others and thus impart immunity which lasts longer than others. Meanwhile we sometimes opt for a vaccine which can be tolerated better by all over an older one = even if that means the immunity does not last as long. It just depends. Have a nice day.
Richard Gregory
Because not all infections (or vaccinations) result in lifelong immunity. Norovirus, for example: your immunity only lasts for 3-6 months. Lifelong immunity can also weaken even if it remains. And lastly, you have to have flu shots every year because the virus rapidly mutates and whlst you remain immune to the old one, you have noprotection against the new version. That is also why there is no vaccine against the common cold: there are just too many viruses and they change too rapidly. It is an example of the eternal war between the immune system and viruses.

the researchers studied a sample of 1,100 healthy children and young adults in Rochester, as well as over 1,000 participants from the U.S. Naval Health Research Center in San Diego as the control group. The Navy members, aged 18 to 40, were all healthy and recently vaccinated, and represented a cross-section of ethnic groups. The study also looked at a subset of a recent immigrant population from Somalia in Rochester. The Minnesota case studies were done in cooperation with the Rochester Epidemiology Project. "The significance of the findings is that in the future we may be able to create vaccines for specific groups or even individuals based on their genomic and other characteristics," says Dr. Poland. "That may mean adjusting doses for some or being able to treat larger populations with the same vaccine if the dosage is less." if you are a refugee you are more vulnerable to be experimented on !!!!!!!!! be aware of these rats.

I remember I hated going to the hospital before first day of school as a child. Obviously the waiting room was boring but I hated getting a shot that 2 or 3 nurses had to hold me down because I was freaking out over a needle. But I later learned I been vaccinated throughout my life and am proud of my mom. Sorry for being a huge bitch over a needle.
