Flu Vaccine Ingredients – What Is Injected Into the Body?

Flu vaccine ingredients

The flu epidemic seems to have risen recently, especially in states such as California where the death toll due to severe influenza was confirmed at 318. Doctors have been persuading people to get the flu shot in order to prevent the sickness from spreading, but ironically, not many have asked what ingredients are actually put in the flu vaccine. What is being injected into your body?

The CDC (The Center for Disease Control and Prevention) encourages vaccinations during cold season, stating that everyone who is at least 6 months of age should receive a flu vaccine. Health officials also recommend that individuals at high risk of getting the flu should also receive the vaccine. This includes women who are pregnant, people older than 65 and those with chronic diseases.

So how does the flu vaccine work?

The flu shot causes antibodies to form in the body a couple of weeks after receiving the vaccine, which then provides a defense against the viruses obtained in the vaccine. There are numerous kinds of strains of influenza, which is divided into type A (such as H1N1 and H3N2), B or C viruses. Type A and B viruses are the strains known to cause seasonal epidemics and occasional deaths. This year’s seasonal vaccine fights off three flu viruses: two influenza A viruses, (H3N2 and H1N1) and one influenza B virus.

Interestingly enough, the flu vaccine is not always effective because it only guards against the viruses that are enclosed in the shot. There are hundreds of other strains that people are exposed to that are not in the vaccine that can still cause many people to become ill. So is receiving the flu vaccine really protecting the body from infection?

Flu vaccine Ingredients – What is injected into the body?

Although flu vaccines shield the body from the viruses enclosed in the shot, the vaccine itself can also cause side effects and/or complications. Common side effects include: pain at the injection site, runny nose, wheezing, headache, vomiting, muscle aches, fever, cough and sore throat. Allergic reactions to the vaccine could also cause hives, swelling, trouble breathing, accelerated heartbeat, dizziness and weakness.

So what is in the vaccine that causes these reactions? The two flu vaccines available this season are Flucelvax and Flublok.

Flu vaccine ingredientsFlucelvax contains: Madin Darby Canine Kidney (MDCK) cell protein, MDCK cell DNA, polysorbate 80, cetyltrimethlyammonium bromide, beta-propiolactone, and a phosphate buffer. Here is a breakdown of the ingredients:

Madin Darby Canine Kidney (MDCK) cell protein – inactive dog kidney cells

MDCK cell DNA – inactive dog DNA

Polysorbate 80 – an emulsifier derived from polyethoxylated sorbitan and oleic acid that is often used in foods

Cetyltrimethlyammonium bromide – a buffer solution for the extraction of DNA and an effective antiseptic agent against bacteria and fungi

Beta-propiolactone – a disinfectant used to sterilize vaccines, blood plasma, tissue grafts, surgical instruments and enzymes. One of the 13 OSHA-regulated “reasonably anticipated human carcinogens.” (A carcinogen is a substance capable of causing cancer in living tissue)

Phosphate buffer – phosphoric acid

Due to the fact that hundreds of Americans have been unable to receive the flu shot due to an egg allergy, manufacturers developed the Flucelvax vaccine which does not contain eggs. Instead, virus strains are matured in canine kidney cells and then deactivated and inserted into the vaccine.

There have been no studies that confirm using canine kidney cells and canine DNA to culture the flu virus strains incur health problems in humans. Although it is highly likely that many people would have an ethical objection to receiving the vaccine if they knew how the flu shot was developed.

In addition, a study from the National Toxicology Program with the Department of Health and Human Services showed that beta-propiolactone caused tumors in both rats and mice at several different tissue sites and with several different routes of exposure. Based on the evidence of carcinogenicity from studies in experimental animals, beta-propiolactone is reasonably anticipated to be a human carcinogen.

It is quite interesting that both health and government officials are persuading the entire United States population to inject disabled canine DNA, neutralized canine kidney cells, and potential cancer-causing agents into the body. The flu vaccine is not even guaranteed to protect against all strains of the flu virus; in fact, it only protects against three.

It is extremely important for anyone who is considering obtaining a flu shot to understand the flu vaccine ingredients and to know exactly what is being injected into the body. Is it really worth purposely getting sick from the flu shot when the chances are slim that the vaccine will shield the body from the type of virus each individual is exposed to? The decision is up for the taking.

    My thoughts? Simply using common sense will guide each of us in the right direction. Unfortunately common sense is lacking among the general population who believe what they hear on TV, follow what the government says or their doctors say blindly without taking responsibility for their own life their own health and informing themselves. If you think injecting chemicals like formaldehyde and heavy metals like aluminum and mercury are going to do your body good then you are a lost soul in the wilderness. Again it’s common sense. The human body will not function properly if burdened with toxic chemicals. Period. This includes the immune system which is key in fighting off viruses. For those who think children who are not vaccinated pose a risk, think again. It’s the children who have been vaccinated who can potentially shed the virus hence the recent sudden emergence of outbreaks among those who were vaccinated. If you still think vaccines are a good idea then how about we keep the schedule down to what it was in the 60’s which is my mom’s generation. Now their are over 36 shots!! That’s a huge increase of chemicals and metals being injected into each child before the age of 6 years old. Seriously, I don’t see how it could be any more obvious. 1 in 6 children with some sort of developmental disorder. If the trend continues we will be looking at a future where most of the adult population will have neurological disorders. Please see the blatant truth that is staring you in the face. Educate yourself.

    Simple human biology tells us that injecting foreign substances into our bodies will always create some effect, the question to ask is what kind of effect and when?

  3. Judith   December 3, 2014 at 9:08 pm

    The CDC admits that the flu vaccine is almost useless – so why submit yourself to such a toxic coctail. Did you check that you are getting the thimerosal mercury free one (you must request) and aluminium has been linked to a higher Alzheimer’s risk.
    Ninety-nine of 102 USS Ardent crew members, 24 of the 25 with ILI symptoms, and 17 of 18 crew members with confirmed influenza A (H3N2) infection had received the 2013–14 influenza vaccine ≥3 months before the outbreak. Vaccinations had been administered at local naval health clinics and at a vaccination fair conducted by Naval Medical Center San Diego. Of the 25 crew members with ILI symptoms, 16 were vaccinated via intradermal injection, eight via intranasal mist, and one had not received vaccination.

    I understand not getting the flu vaccine but people that don’t vaccinate their children are retarded. They’re going to be the ones that cause another pandemic and then blame the government when it’s their own damn fault that they don’t understand simple human biology.

    • DC   June 5, 2017 at 8:23 am

      Kayla, Nice try. If children who are not vaccinated can permanently harm children who are vaccinated, then you are admitting the vaccines don’t work. This is completely illogical. Your only claim is that you care about the children who are not vaccinated. I care about these children too, but I also care about the vaccinated children who have died, become Autistic, have gotten Gullain-Barre disease and a host of other negative effects vaccines are known to cause. It’s the parent’s decision to make, not the government’s. If you think otherwise you would be right at home in Stalin’s Russia, Chairman Mao’s China, and Germany circa 1935-45. I’m 55. Children today (on average) receive 12 times as many vaccines as children did in the ’60s and ’70s. This is what is retarded: allowing Pharmaceutical companies to bribe politicians who then attempt to legislate mandatory vaccinations which harm the population and line the pockets of Big Pharma.

    This one is for Lee. The reason the mortality rate is lower now then in the early 1900’s is due to the advancement in modern medicine. The mortality rate was high because because most people had a weak immune system, heck they didn’t know what an immune system was. Today people are healthier and for the most part have a healthier immune system that helps fight off most diseases. Think of it, we have easier accessibility to doctors, we have aspirin, vitamins, a lot of people exercise in one form or another fairly regularly. These, among other benefits we have that people in those days didn’t have is the reason why the mortality rate is lower now. It is not because of the flu vaccines. It’s in spite of the flu vaccines. There are natural medicines that help prevent or cure the flu without any serious side effects like Beta 1, 3D Glucan one of the best products to keep the immune system strong to fight off diseases, even cancer. There is Carnivora, that can identify any foreign cell, (viral or bacterial) that doesn’t belong in your body and kills it. President Reagan took carnivora and was pleased with it. Last but not least, there is Sambucus Immune with elderberry, which you can get any vitamin or drug store. What’s in this little bottle, taken on a regular basis, can keep you from getting a serious cold or the even the flu. Remember, a super strong immune system is the most important part. I don’t get flu shots and I haven’t had a major bout with the flu since I was in my thirties and I am 71 years old.

    I used to get vaccinated and I had several colds and VERY SERIOUS flu, every single year. Since I woke up, over five years ago, discovered what the ingredients were and STOPPED getting vaccinated, I haven’t had EVEN ONE instance of the flu, or even a cold! Back to sleep, all you ignorant zombie sheeple! There is no hope left for this society!

  7. Jim Furr   October 11, 2014 at 5:53 pm

    Anyone who takes these vaccines is very ignorant or stupid. No more needs to be said.

    • Lee   October 14, 2014 at 8:54 am

      anyone who can look at the mortality figures from 1900 – 1999
      can SEE that flu vaccines are not only important but are PROVEN to work.

      • Randy   October 21, 2014 at 7:57 pm

        Just go back to sleep, Lee! YOU are part of the problem!

    • Randy   October 21, 2014 at 8:00 pm

      It doesn’t really matter what you say, Jim. The zombies are too far gone!

  8. Dave   September 29, 2014 at 2:58 pm

    Craziness… Do you really believe that Jonathan? That important decisions about your health are supposed to be made for you by the government? Wow! Do you have any idea how many times the government has been wrong in their statements about what constitutes safe and healthy products and procedures? If the government told you it was safe to drink motor oil, would you trust them? 😉 I doubt you would, but when the public doesn’t stay informed, sometimes corruption slips into the system and lots of people get hurt or sick because they believed something they should have known better to avoid.

    Health is not rocket science and I promise you that the Government is no pro at health matters, though they’d probably love for you to think so.

    I guess I don’t fault you entirely for the trust you’ve adopted, since we are all fed these ridiculous notions daily by many of the powers that be. I am thankful that the USA has an FDA and they do serve a good purpose in general, but it’s important to inform yourself also because “authorities” make mistakes and also fall into diverse temptations where money drives the information and lies sometimes get touted as truth so long as it achieve the desired result. This is nothing new… this has happened for centuries the world over.

    I recently downloaded the app for Android called “Dr. On Demand” (which generally is a great service) but they published an article with more of the same drivel… My favorite line in the article was “without a doubt the flu shot is the best possible protection from the influenza virus.” Excuse me a moment… HAHAHAHAHAHAHAHAHAHA!!! The best possible way? So, what they’re really saying is that the reason why people get the flu is because their bodies have a deficiency of flu virus vaccine… Excuse me again… HAHAHAHAHAHAHAHA!!! Dumbest thing I’ve ever heard in my life! The problem isn’t a lack of flu vaccine, but a crappy immune system, which is BEST resolved by proper diet and exercise. Again, not rocket science.

    If your body gets the proper tools it will resist sickness and disease and recover faster from them. You don’t need trace amounts of poison in a clever concoction of chemicals mixed with dog DNA to fight the flu. You don’t need to blindly trust any official telling you, “It’s okay to just pump this junk into your veins… trust us… it’s good for you.” Get your vitamin D levels checked and then increase them. There’s a great app for your phone called D-Minder that can help with this. Water, exercise, sleep, healthy food… You’ll be amazed at the results. Make sure you’re getting all the nutrients needed to stay healthy.

    I hardly ever get the flu (even when people around me are sick), yet I know others (including my doctor who tells me all the time to get the shot) who take the flu virus regularly and get the flu every season. So this “you need the shot” stuff is just total bunk! It’s absolute nonsense that it stops you from getting the flu. This article was great and concise and truthful.

    To Jonathan.

    I can not believe you are so trusting of these companies.

    When you say they “have a vested interest” and “risking unvestment” that should be the warning bell. Actualy, I think you are having a little joke on us.

    As the old saying goes. Stay away from doctors, they will kill you.

  10. Anne Sewell   March 16, 2014 at 1:23 am

    Tell you what, I am 61, I have NEVER, ever had a flu vaccine and also have never had a serious case of the flu…Take that Jonathan. 🙂

  11. Judith   March 11, 2014 at 11:38 pm

    Yes Jonathan – we should not have to be worried about what happens when we have a vaccine, we should be able to trust those who are paid by our tax dollar however they often have conflicts of interest. In our Australian Newspaper this week a disturbing report that Fluvax was given to children and caused febrile convulsions.at an alarming rate. It had never been tested on children through clinical trials. Two members of our Federal Department of Health and Aging have links to CSL the drug company that made Fluvax by being on their Advisory Board. You see there is money and conflict of interest involved so we cannot simply trust. We have to do our research.

  12. Judith   March 11, 2014 at 10:30 pm

    Stephen, the more I read the more disturbed I get. Perhaps it is a good thing. We need to do our research.

    It is interesting to note that Safety sheets for vaccines clearly state
    Carcinogenesis,, Mutagenesis, Impairment of Fertility

    M-M-R II has not been evaluated for carcinogenic or mutagenic potential, or potential to impair fertility. Pregnancy

    (extract) Virus-based vaccines are made in living cells (cell substrates). Some manufacturers are investigating the use of new cell lines to make vaccines. The continual growth of cell lines ensures that there is a consistent supply of the same cells that can yield high quantities of the vaccine.

    In some cases the cell lines that are used might be tumorigenic, that is, they form tumors when injected into rodents. Some of these tumor-forming cell lines may contain cancer-causing viruses that are not actively reproducing. Such viruses are hard to detect using standard methods. These latent, or “quiet,” viruses pose a potential threat, since they might become active under vaccine manufacturing conditions. Therefore, to ensure the safety of vaccines, our laboratory is investigating ways to activate latent viruses in cell lines and to detect the activated viruses, as well as other unknown viruses, using new technologies. We will then adapt our findings to detect viruses in the same types of cell substrates that are used to produce vaccines. We are also trying to identify specific biological processes that reflect virus activity.

    These methods will enable FDA scientists to help manufacturers to determine whether their specific cell substrate is safe to use for vaccine production. The methods our laboratory are developing and testing will help to ensure the production of safe and effective vaccines in two ways: 1) FDA will be able to develop testing guidelines for manufacturers who use new cell substrates for producing vaccines; and 2) FDA will publish the new methods it develops in peer-reviewed scientific journals, thus making them readily accessible to all manufacturers.

    Fear mongering much? Anti-vaxxers disturb me.

    • Jonathan   March 11, 2014 at 10:47 pm

      exactly. This article makes for disturbing reading. The decision is up for the taking? we aren’t supposed to make decisions regarding vaccines, these decisions are meant to be made for us, and any suggestion that perhaps we should make our own informed decision is reckless and costs lives. I feel creepy and ashamed reading vaccine ingredient lists or efficacy data. It simply shouldn’t be in the public domain; there are people with the sufficient training and vested interests who are in the best position to protect us and they hardly need Joe Blogs stirring trouble and risking investments and/or lives.

      • Geo   March 13, 2014 at 9:54 am

        @Stephan and @ Jonathan
        Seriously? I think it is much more disturbing to blindly accept anything. Informed decisions are the best decisions. To not want a flu vaccine because it has not been properly vetted/tested in the short time span it is created every year does not make a person an “Anti-vaxxer”. (Never heard this derogation before) Vaccines for Measles, Mumps, and Rubella have been tested exhaustively and have documented efficacy. The same is not true of Flu vaccines as can be seen by this well sourced blog.
        The comment, “we aren’t supposed to make decisions regarding vaccines, these decisions are meant to be made for us…I feel creepy and ashamed reading vaccine ingredient lists or efficacy data.” Have you ever heard of a lemming? Has everything sanctioned by non-profits, our fearless leaders, doctors or scientists always been completely safe or permanently deemed to be for the best? They are working from theories. Theories can be faulty. We have to decide through informed research which theories we can accept and which we feel are too risky, at this time. I believe this to be especially true when for profit organizations, like the companies manufacturing vaccines, are in the mix driving for our blind adoption.
