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

    Kurzgesagt – In a Nutshell3 months ago

    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.

    I think the saddest part of the whole anti-vax b/s is they not only have no idea how vaccines work, they also lack even fundamental knowledge of what autism is. It's like 2 different schools of ignorance had a baby (that immediately died of measles).

    Partially correct Ashley. You are correct in that cancer represents an idiopathic aberration with your cellular makeup rather than an external pathogen as with infectious diseases. Yet your body periodically produces aberrant cells as a normal byproduct of the cellular mitosis which drives our bodies. Your immune system will usually identify these defective cells and instruct them to commit "suicide" via apoptosis. When that system breaks down however = we see tumors and cancer result. So cancer represents a dysfunctional immune system and accordingly there is nothing to "learn". All we can do is to try to destroy those aberrant cells externally via things like chemo or radiation and hope the immune system will kick in to do the rest. Moral of the story: because it failed to do it's job to begin with = it can similarly fail again. That is why we sometimes see reoccurrence after a time or else cancers affecting other systems. Something is amiss with the body which it can not overcome = making it subjective to the individual alone. We can prevent measles because it's cause is a single known virus. Cancers on the other hand can be the result of multiple etiologies making them difficult to pin down. Have a nice day.

    Cancer is a little different. Cancer is a mutation from cells already inside your body so its nothing you contract. Your body may learn from previous cancer, but cancer cells are much harder to destroy

    Wait isn't autism linked to genetics? Idk tho I'm 15

  78. Vary Olla

    Vary Olla11 hours ago

    Yes Epic. Children are born autistic as a result of something in their genetic makeup results in neurocognitive deficits. Unless those deficits are severe in nature however = an autistic child will not usually manifest signs of that autism until a latter point in their lives as their brains are still developing. This is what I mean. Human children are born with the capacity for language and movement. Yet a newborn can not immediately speak anymore than it can get up and walk or run like say a baby gazelle. That is because it's brain is still developing those capabilities. So it will coo and grasp at it's feet at first ---------> then it will roll around on the floor and attempt to crawl = and eventually it will make sounds and try to stand and then walk. Likewise a doctor will usually wait until 12 months or later to assess an infant for neurocognitive deficits because the child can not tell us what it is feeling while the doctor can not accurately gage some capacities absent that verbal interaction. Meanwhile vaccinations sometimes overlap this timeframe. Accordingly some parents will conflate a diagnosis of autism with the timing of those vaccines as causing it = wrong. Lastly is after the fact neurological damage which results in "autism-like" behaviors. Before there was an MMR each year in the US we used to see thousands of children hospitalized with encephalitis from catching measles. Today while it is possible for the MMR to cause encephalitis = thankfully that is a rare occurrence. Because both the vaccine and the disease cause the same problem = the virus and not the vaccine per se is responsible. So a child who receives the MMR and develops encephalitis which causes some neurological damage resulting in autism-like behavior would be no different than say a child who received perhaps a blow to the head from a baseball bat and who suffered brain damage as a result which precipitated autism-like behaviors. Do baseball bats then cause autism = of course not. Rather such a child is reflective of those we used to see anyways in the time before the MMR who could not tolerate exposure to measles and who reacted harshly as a result. Most often those children who react badly to being vaccinated = have some underlying health issue which is driving the reaction since almost all children vaccinated do not react as such. That makes the preexisting health issue responsible and not the vaccine as absent it = the child would not have reacted as they did to the vaccine. Have a nice day.

    The rise in detection which as noted Shinto is directly correlative to the variables I made note of. Incidence of autism screening has risen = but then we are looking harder for it as the population in turn increases. Accordingly one would expect to see a rise in identified cases even though also as noted those identified merely reflect some level of deficit rather than all being severely impaired. So children such as those who might say 30 years ago would have simply fallen through the cracks of society are today being identified thanks to better surveillance. Have a nice day.

  102. The Shinto Railfan

    What rise?

  103. Vary Olla

    Vary OllaDay ago

    Follow the white rabbit Neo: 1 - since 1980 as alluded to by others the US population as grown by 1/3rd = or about 100 million more people. 2 - autism awareness began to take off in the early 1980's. By the early 1990's the DSM definition was expanded to include more neurocognitive issues to create ASD. 3 - a few years later the American Pediatric Association issued guidance for doctors to screen more aggressively for autism. 4 - post-2000 has seen an increase in awareness + and increase in research. Meanwhile expanded healthcare coverage has resulting in more children being seen regularly by doctors = thus more screenings happen. 5 - also as a result of #4 the reporting system has improved making it easier to identify any children who are determined to have "some level" of deficit. Note I said some level. Many of those children reported live fairly normal lives and only have as noted varying degrees of deficit and do not automatically mean children with severe impairments. Moral of the story: any time you increase a relative population + expand the definition of what you are looking for + devote more resources to finding that thing + and improve the system for reporting = you will invariably see more children swept up under that broader umbrella as we see. Have a nice day.

    @Toby Conner you are assuming the license was revoked for good reason. Actually two doctors had their license revoked for authoring the study. The other took it to British High Court, and the judge's analysis concluded the decision had no merit. Wakefield did not take the matter to court, and possibly the conclusion would have been different, but I offer this here as just one suspicious facet of this case. There are others, and not least of which is the matter of the Cdc whistle blower. Whatever is ultimately found Re Wakefield, Vaxxed is not about him, and intelligent viewers should be capable and willing to investigate and decide the merit of the case made in the film. That they do not consider it necessarily bodes ugly for any system they're involved in....there's such a thing as herd immunity, and there's also a thing called group think.

    Vary Olla12 hours ago

    Not entirely jim. While it is true that pathogenic viruses can precipitate problems for humans such as the MeV measles virus as an example. Yet some viruses which our progenitors were exposed to long ago have become an essential part of our genome of which around 5-8% represents remnant viral DNA. An example is Syncytin-1 which represents a gene that is behind some of the protein production in placental development in humans. Some viruses simply invade a cell and force it to produce more viruses internally = after which the cell explodes releasing those viruses into the bloodstream. Others however referred to as ERV's - or Endogenous Retro Viruses - enter a cell and part of it incorporates into the cellular makeup via transposition - hence their being called transposons. Those gene segments are then passed on to each new cell when it replicates = becoming part of the host's genomic structure in some cases. So Synctin-1 represents an ERV which originated as a primate virus millions of years ago. Our progenitors were exposed to it ---------> it fused with their DNA and was perpetuated forward = to now be an essential part of the human placenta responsible for us being here as it helps regulate essential proteins which helped you grow into a viable baby. Have a nice day.

    @Vary Olla thanks. ive been wondering what all the "junk" dna in our dna is from as well, i was wondering if this stuff which is apparently useless are mutagens from viruses or other outside anomalies which have left an impact on our dna but dont seemingly have much use? i had wondered as a result if this stuff gets passed on as a result of viruses contracted from memory cells and the like...

    No = they do not. Humans lack the capacity to pass on acquired immunity to their offspring. Accordingly with each new generation born the process begins anew and the child is born with basically a blank slate as far as their immune system. We so however see what is referred to as "passive immunity" from the mother after birth = but that is transitory. As a result of a shared blood supply with the mother the infant will have some circulating antibodies in their own bloodstream. Those however will begin to die off - not to be replaced - after a few weeks. Meanwhile if the mother breastfeeds their infant then the child can acquire some IgA immunoglobulins in the colostrum and breast milk = but again that is temporary and represents things the mother "loans" the infant until those cells die off..........again leaving the child with only it's own underdeveloped immune system. IgA helps to protect the child against "some" pathogens who typically access the body via the epithelial cells of the oral-GI tract as it helps to reinforce what could be viewed as surface immunity = or your first line of defense. If a pathogen however manages to access the infant's circulatory system then it has a problem as it lacks the circulating immune cells so important to fighting off infection. Those cells only develop in response to exposure to and defeating by the immune system of pathogens and are not passed on by the mother. That is of course why we vaccinate = to facilitate that exposure while minimizing the risks of severe reaction to said exposure. Have a nice day.

    I don’t think they do. After all, they’re cells, so they don’t really alter your genetics.

    Im an anti vaxxer! Please crucify me with your hive mind and repetitive jokes. My arguement... it shouldnt be the fucking law to accept a "practice" (which is what medicine is. Its not a fucking science.) The government doesnt have the right to tell you what to put in your body. Thats the fucking arguement. Not whether they work or not. Its the fucking right to be able to choose what goes in your body and your kids. Your allowed to have your OWN ideas and beliefs. You all are probably the same idiots that think the sun has nothing to do with climate change. I bet none of you even know what solar forcing is. Anyways... Please be as rough as you like. 😈

    @Omer Feldman Yofiël Vaxxed, directed by Andrew Wakefield being the discredited doctor who acknowledged he made fraudulent claims and fabricated data in his studies? The same man who had his certificate to practice medicine revoked for falsifying his studies results to receive financial gain for his own competing vaccination and witness testimony against his competitors? I am aware of Vaxxed as it happens. It certainly isn't "well documented", it isn't well researched, it most certainly isn't supported by science or scientific studies but you do you.

    @Christian Dzwonkowski certainly you don't. The "secret" information is well documented in Vaxxed, and is there for any nitwit to examine.
