How do vaccines help babies fight infections? | How Vaccines Work

This is baby Jack. Vaccines help Jack fight infections by introducing a small number
of antigens into his body. Antigens are parts of germs that cause
Jack’s immune system to go to work. After Jack gets a vaccine, his immune system
will remember the vaccine antigen and attack that germ if it ever invades his body again. The antigens in vaccines are weakened
or dead, so they do not cause illness. Vaccines contain only a tiny
fraction of the antigens that Jack encounters in his
environment every day. It’ll take a few weeks for
the vaccines to start working, and Jack may need more doses
later to best protect him. That’s why Jack’s parents are following
the recommended immunization schedule – because it is designed to give him the best
protection possible from 14 serious diseases. Learn more about childhood immunizations. Visit
or talk with your child’s doctor.

  • What a cute litty bitty poopaganda video.
    Too bad they aren't telling the truth……That vaxes are breeding superbugs the same way antibiotics did.

  • How do they help?
    They don't.
    They destroy the immune system and make you sick and many even kill.

    Reject the propaganda. Reject the poison.

  • Epitaph: Listen to a top neursurgeon explain why a child up to two years should never receive a vaccine.
    Dr Russell Blaylock jokingly states "the average doctor doesn't know a child has a brain in their head"
    He says this informing us he knows what happens when a child is vaccinated.
    An immune response results in the creation of excitotoxins, as intended.
    The problem is the childs brain is still growing, with neuronal connections being established.
    Specifics chemicals are created to necessitate, one that should not be disturbed during this process.
    This is where learning disabilities and or even autism is a potential threat, when connecting neuronal pathways is interrupted.

  • CDC: begone anti vax weaboos

    anti vax mums: reeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

  • Is there anyone involved in the approval process of the vaccines also having prior worked for that company or have a job offer after there bid at the cdc?

  • Are the drug companies everyone is supporting in the comments the same drug companies in just about every other medical video and congress session being called evil and out of control?

  • Please, can a pro vaxer send me a link to evidence of a double blind placebo safety study for any complete vaxine where the placebo used is not another drug or vaccine and the study runs for more than 4 years. It would really help convince me. It is the standard for any new medication is it not??

  • “What you have to understand is that the vaccine regimen changed dramatically around 1989. The reason it changed, Tucker, is that Congress, drowning in pharmaceutical industry money, did something they have never done for any other industry – they gave blanket legal immunity to all the vaccine companies.

    “So that no matter how sloppy the line protocols, no matter how absent the quality control, no matter how toxic the ingredients, or egregious the injury to your child, you cannot sue them.

    “So there’s no depositions, there’s no discovery, there’s no class action suits. All of a sudden vaccines became enormously profitable.”

    The enormous profits in the unregulated industry meant Big Pharma companies raced each other to produce new and unnecessary vaccines to pump into newborn children – often dozens at a time.

    “It became a gold rush for the pharmaceutical industry to add new vaccines to the spectrum.”

  • How much $$$$ did you got from the big pharma to create this video.
    The government agencies are in the pocket of big pharma corporation. The establishment is rigged. All is about $$$$, nothing about common sense or health of the people.
    There are not neutral trials about vaccines, all the tests are performed by the big pharma, they decide if the vaccine is good or not. And of course all the vaccine are good.
    A normal person should take a vaccine every day since is born till dies.
    No transparency. The vaccine are just commercial items/products forced onto people to make $$$$ profit and good shares for the big chemical corporations.
    The medical establishment it is a sham. All is about $$$$. Nothing about health.
    The few sources that speak against and try to uncover the false propaganda are censored and removed.
    CDC, FDA, EPA are in the pocket of the big $$$$. The lobby ($$$$) drives everything. Just mass manipulation for navies.
    You have zero credibility.

  • shills going nuts in these comments…. lol. we're not injecting our kids with aluminum, guys. sorry. 🙂 check out suzanne humphries md.

  • You can’t sue the Pharmaceutical companies. They have no liability. Would you fly with an Airline, if they had no liability… hmmmm

  • Do vaccines help babies fight infections – of course not. The human body doesn't have it's own immune system up and running until 3 years old. Baby vaccinations are for training the mother to bring the child in for vaccines. For children older than 3 years, the antibody = protection link is a theory and has not been found. We are being force fed fake science in cartoon format, as vaccines have dumbed everyone down now we need cartoons in order to understand the propaganda big pharma is feeding us. And it is actually the smallest particles, aluminum and other nano sized particulates, that is making the entire population very sickly. We are at war. Vaccines are bio-warfare. The perpetrators know this. How they don't immunize is known. How they harm our bodies is known. It's what they want. Unhealthy and customers for life.

  • I hope people understand they have been lied to on this bush league cartoon…and that they probably paid for it….

  • What if the government released a deadly virus easily preventable by vaccines and released it so that all the anti backers would either get vaccinated or die? Everybody who can’t get vaccinated should take a vacation though it would be like the purge

  • breast milk is the best vaccine for babies. no side effects and its free. oh, but nobody makes money from breast milk, so i guess that is why it is not promoted.

  • In 2018, Lyons found that the doses by weight of aluminum adjuvants used in vaccines for infants were calculated to be a lot more toxic than initially imagined by the medical community.

    FDA regulations require safety testing of constituent ingredients in drugs (21 CFR 610.15). With the exception of extraneous proteins, no component safety testing is required for vaccines or vaccine schedules. The dosing of aluminum in vaccines is based on the production of antibody titers, not safety science. Here we estimate a Pediatric Dose Limit that considers body weight. We identify several serious historical missteps in past analyses of provisional safe levels of aluminum in vaccines, and provide updates relevant to infant aluminum exposure in the pediatric schedule considering pediatric body weight. When aluminum doses are estimated from Federal Regulatory Code given body weight, exposure from the current vaccine schedule are found to exceed our estimate of a weight-corrected Pediatric Dose Limit. Our calculations show that the levels of aluminum suggested by the currently used limits place infants at risk of acute, repeated, and possibly chronic exposures of toxic levels of aluminum in modern vaccine schedules. Individual adult exposures are on par with Provisional Tolerable Weekly Intake "limits", but some individuals may be aluminum intolerant due to genetics or previous exposures. Vaccination in neonates and low birth-weight infants must be re-assessed; other implications for the use of aluminum-containing vaccines, and additional limitations in our understanding of neurotoxicity and safety levels of aluminum in biologics are discussed.

    But, this brought back memories of an earlier warning in 2012 along similar lines.

    Immune challenges during early development, including those vaccine-induced, can lead to permanent detrimental alterations of the brain and immune function. Experimental evidence also shows that simultaneous administration of as little as two to three immune adjuvants can overcome genetic resistance to autoimmunity. In some developed countries, by the time children are 4 to 6 years old, they will have received a total of 126 antigenic compounds along with high amounts of aluminum (Al) adjuvants through routine vaccinations. According to the US Food and Drug Administration, safety assessments for vaccines have often not included appropriate toxicity studies because vaccines have not been viewed as inherently toxic. Taken together, these observations raise plausible concerns about the overall safety of current childhood vaccination programs. When assessing adjuvant toxicity in children, several key points ought to be considered: (i) infants and children should not be viewed as "small adults" with regard to toxicological risk as their unique physiology makes them much more vulnerable to toxic insults; (ii) in adult humans Al vaccine adjuvants have been linked to a variety of serious autoimmune and inflammatory conditions (i.e., "ASIA"), yet children are regularly exposed to much higher amounts of Al from vaccines than adults; (iii) it is often assumed that peripheral immune responses do not affect brain function. However, it is now clearly established that there is a bidirectional neuro-immune cross-talk that plays crucial roles in immunoregulation as well as brain function. In turn, perturbations of the neuro-immune axis have been demonstrated in many autoimmune diseases encompassed in "ASIA" and are thought to be driven by a hyperactive immune response; and (iv) the same components of the neuro-immune axis that play key roles in brain development and immune function are heavily targeted by Al adjuvants. In summary, research evidence shows that increasing concerns about current vaccination practices may indeed be warranted. Because children may be most at risk of vaccine-induced complications, a rigorous evaluation of the vaccine-related adverse health impacts in the pediatric population is urgently needed.


    And the concern was raised again—especially concerning synergistic detrimental effects when mingled with mercury adjuvants—in this paper from 2015.

    Currently, ethylmercury (EtHg) and adjuvant-Al are the dominating interventional exposures encountered by fetuses, newborns, and infants due to immunization with Thimerosal-containing vaccines (TCVs). Despite their long use as active agents of medicines and fungicides, the safety levels of these substances have never been determined, either for animals or for adult humans—much less for fetuses, newborns, infants, and children. I reviewed the literature for papers reporting on outcomes associated with (a) multiple exposures and metabolism of EtHg and Al during early life; (b) physiological and metabolic characteristics of newborns, neonates, and infants relevant to xenobiotic exposure and effects; (c) neurobehavioral, immunological, and inflammatory reactions to Thimerosal and Al-adjuvants resulting from TCV exposure in infancy. Immunological and neurobehavioral effects of Thimerosal-EtHg and Al-adjuvants are not extraordinary; rather, these effects are easily detected in high and low income countries, with co-exposure to methylmercury (MeHg) or other neurotoxicants. Rigorous and replicable studies (in different animal species) have shown evidence of EtHg and Al toxicities. More research attention has been given to EtHg and findings have showed a solid link with neurotoxic effects in humans; however, the potential synergic effect of both toxic agents has not been properly studied. Therefore, early life exposure to both EtHg and Al deserves due consideration. SOURCE:

    Aluminum in the central nervous system (CNS): toxicity in humans and animals, vaccine adjuvants, and autoimmunity.

    We have examined the neurotoxicity of aluminum in humans and animals under various conditions, following different routes of administration, and provide an overview of the various associated disease states. The literature demonstrates clearly negative impacts of aluminum on the nervous system across the age span. In adults, aluminum exposure can lead to apparently age-related neurological deficits resembling Alzheimer's and has been linked to this disease and to the Guamanian variant, ALS-PDC. Similar outcomes have been found in animal models. In addition, injection of aluminum adjuvants in an attempt to model Gulf War syndrome and associated neurological deficits leads to an ALS phenotype in young male mice. In young children, a highly significant correlation exists between the number of pediatric aluminum-adjuvanted vaccines administered and the rate of autism spectrum disorders. Many of the features of aluminum-induced neurotoxicity may arise, in part, from autoimmune reactions, as part of the ASIA syndrome.

    And the same researcher that busted the chops of the FDA on aluminum toxicity in infants is also helping to explain around a number of the misunderstandings about how this particular metal works as a toxic substance and explains the mechanism by which aluminum in cells deforms proteins to provoke an autoimmune reaction in the body.

    James Lyons-Weiler, PhD discusses Aluminum Toxicity


  • Why has the CDC expanded the vaccine schedule so much over the past 40 years without ever doing a controlled, randomized trial? It sounds totally irresponsible to make an official vaccination schedule, exposing millions of children without determining the new schedule has a better risk-benefit profile over the old schedule.

  • Anti vaccinators logic

    bridge : is 99.99987 percent safe to cross

    Anti vaccination people : guess I'll swim in these alligator infested waters

  • Simply comes down to whether you trust what government wants to inject in your blood stream or not. Certainly a personal choice if there ever was one.

  • You can't convince me, this is all FAKE NEWS. Vaccines cause autism, HIV, and are made from poison. They cause death as well. If you were to do the real science, you would find that there are facts to back this up, and they are a COVER-UP by the GOVERNMENT. The government puts harmful chemicals in our vaccines, leading our children to be mind-controlled by the government.

  • Vaccines are designed to weaken your natural immune system, in order to make your body dependent on the vaccine. It's a money grab for the medical industry. Your body already has the ability to learn, rebuild, protect and even become stronger by design. Why do we need vaccines? I see why Hollywood keeps making these movies about the zombie apocalypse.

  • Vaccines are poisonous read all about it. Just use your brain and understand that there is no needle that is safe. Not a tattoo not heroin and especially not vaccines. REVOLT against the new world order YAHUSHA SAVES

  • If these shots are supposed to help kid's, Then Explain to me why soooooo many children are dying because of it. I've seen and heard reports of children dying because of the shot.

  • We humans are definitely not supposed to inject chemicals into our body. The truth is that it is very dangerous, and is putting lifes into great risk. Vaccines should be 100% illegal!

  • Dear all anti vaxxers sure vaccines have deadly chemicals like mercury but did you know that apples have Cyanide and there not harmful to us and water has hydrogen and it’s safe to us and in fact need water to live

  • Full of lies. Search for "Cancer Laced Vaccines". It's in-depth and factual. They aren't helping, they are making us sick so they can continue to get rich. Bioweapons! Only the brainwashed fools will comment.

  • At least the anti-vaxxers did something good: help start some other deadly outbreak that make humans extinct before the AI takeover.

  • I think its funny that anti-vaxxers blame vaccines for autism and brain damage. No Karen, its just your genes has been passed on.

  • There have been babies dying of vaccinations. Especially because their immune system is not really ready for such "attack". If side effects can mean death, the healing method is very doubtful. But you probably will not listen until you experience some things yourself. You probably will not read about academics critizising vaccines either, because we usually only want to spend our time with things that are in harmony with our opinions. That is how human nature is, after all.

    Good doctors know not to give a too strong medicine to someone that is already weak to begin with. Else it could result in death. Why not appy the same to this? Babies do not have a strong "defense mechanism" inside their bodies to begin with. But god forbid, you do not want to hear this, do you? The writer's intention solely lies in letting you think for yourself and see both sides of a coin.

    Nevertheless, I wish you a wonderous day

  • Guys antivaxxers are good for us! They keep the population down by instantly letting their kids into a tightrope where falling into the lava below would mean death instead of us normal people who just give them fire protection armor!

  • Jesus i've been slashing anti vaxxers with K N O W L E D G E for 2 hours i think i can't last much longer.. someone take the lead for me please!

  • The reason there are side effects to vaccines are due to the fact that the virus inside the vaccine is fighting back stronger than it should, most likely caused by giving a breed that is stronger than it should be. Vaccine side effects are rare, because vaccines are weak/dead viruses that can be easily dealt with by the immune system. The reason we get vaccines is because whenever we get a disease for the first time, our body doesn't know how to fight it and our intelligence cells need time to figure that out, which allows the disease to attack further. After the disease is dead, memory cells are produced, which remain dormant and remember everything about the disease and how to fight it. When the disease comes a second time, memory cells basically are your commanders that coordinate the attack and quickly get antibodies produced to attack the disease. Vaccines allow our immune system to fight that disease for the first time and create memory cells, but in a safer way. In a nutshell, vaccines are teachers for your immune system (and intelligence cells are the students, memory cells are the students that graduate from high school)
