The Side Effects of Vaccines - How High is the Risk?

Kurzgesagt – In a Nutshell
Dive into sources and further reading here:

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?

Ummmmmm, just a quick question.... If your kid is vaccinated, isn't that supposed to protect them from the virus? So why would it matter if someone else's child isn't vaccinated? Your kid got the vaccination so they're safe right? My opinion if someone decides not to vaccinate their child, isn't that their choice? I bet these people on here insulting the parents that don't choose to get their children the shots would change their mind if their child got these shots and ended up a special needs child afterwards, or with ADHD! It happens all the time! It happened to my daughter! Think about it.....

Two reasons you're wrong. 1: Some kids can't get vaccinated. 2: If you contract a disease, it can mutate whilst in you, ergo making it able to make the jump to me, even if I'm vaccinated because our "Memory cells" don't detect it.

Some kids can't get vaccinated for medical reasons. The only way for them to be protected from diseases is through herd immunity so it affects them if not everyone is vaccinated. 8:56

The video doesn’t address toxic preservatives contained in some vaccines. All of the side effects discussed are the acute side effects and not the effects of a child’s not fully developed liver to filter out these toxins.
In addition it video failed to point out that many of the cases of measles now occurring are in individuals who previously received the vaccination. Thus effectivity of the vaccines is questionable and is not addressed.
Bottom line, Parental Right to choose should be allowed in all cases of medical procedures regarding their children. Parents have the right to decide and accept whatever risks apply to their family. No one needs a Nanny State telling them that we have to do anything.
Jasmine Lyall
Jasmine Lyall - 5 hours ago
Although measles can occur in people who have been vaccinated, it is much less likely than in someone who is not vaccinated. This is shown by the huge decrease in measles cases since the vaccine started being produced. The problem is, whether or not you vaccinate your kids affects people who are unable to vaccinate their kids for medical reasons. 8:56

Because (a) it takes time from the shot to build full immunity, (b) the immunity is not 100% perfect, it just reduces your chanc eof getting flu - a LOT - and reduces the severity of the flu if you get it and (c) every year they have to make a "best guess" on which strains of flu are likely to be prevalent in that year; different strains dominate in different years and the virus mutates a lot as well. That's why you have to have a flue shot every year, to keep you up to date. Sometimes this "best guess" is wrong. It is also perfectly possible that your brothers just got unlucky and et a flu virus that wasn;t included in the shot. It;s not possible to produce a vaccine to cover every strain there is. Lastly, lots of people think they had flu when they had a bad cold. Flu will make you so sick you can;t get out of bed for a week.

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.
Vary Olla
Vary Olla - Day ago
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.
