Why we immunize–protect children from hospitalization for diarrhea


Update 1. Added more information about the power of the herd immunity written by Tara Haelle.

One of the most recent and important vaccines added to the current schedule of immunization is the rotavirus vaccine, introduced in the USA in 2007. Before the introduction of the vaccine, rotavirus was the most common cause of severe gastroenteritis in US children under 5 years old. Each year, rotavirus caused an estimated 20 to 60 deaths, 55,000 to 70,000 hospitalizations, and nearly half a million non-emergency visits to healthcare facilities.

A study, recently published the Pediatrics journal, concluded that, after the rotavirus vaccines was introduced, the numbers of diarrhea-related illness in US children dropped significantly. Moreover, probably as a result of herd immunity (where transmission through a population is inhibited by individual who are immune to the disease), the study found that the rate of hospitalizations related to the virus dropped substantially in both vaccinated and unvaccinated children.

The research examined health insurance data from across the USA (except for Medicaid, and a few states that don’t report data) for children under 5 years, cross tabulating various gastrointestinal illnesses with hospitalizations and other medical care. It also compared the same information to the vaccination status of those children. Finally, they gathered data about these illnesses from 2001 through 2006 (before the vaccine was introduced) and 2007-11, to compare hospitalization and other medical facility encounters between the pre- and post-vaccine groups.

The researchers determined the following:

  • They ascertained that 58% of the children in the study had been vaccinated against all five strains of rotavirus by the end of 2010, three years after introduction.
  • They determined that rotavirus infection hospitalizations were reduced by 75% in 2007-08 (after the vaccine was introduced) compared to 2001-2006. This data was irrespective of vaccination status, just that the overall population exhibited a reduction in the hospitalization rate.
  • Compared to the average rotavirus rate in 2001-06, the incidence was 60% lower in 2008-09, 94% lower in 2009-10, and 80% lower in 2010-11. Again, this reduction in rate was irrespective of immunization status.

The data support that, generally, the population of under 5 year old children that required hospitalization from rotavirus had dropped significantly after the introduction of the rotavirus vaccine. Again, there appears to be a substantial herd immunity against rotavirus.

However, the comparisons between vaccinated and unvaccinated children was even more dramatic.

  • Children who had received the rotavirus vaccine had 92% lower rotavirus associated hospitalization rate than unvaccinated kids.
  • Vaccinated children had 55% fewer diarrhea associated hospitalizations than unvaccinated ones.
  • Vaccinated children had 31% fewer diarrhea associated emergency department visits.

Setting aside the suffering to the child and parents, this has a huge economic benefit. The reduction in hospitalizations via vaccination has saved the country over US$83 million in direct medical costs in just 4 years. This is money saved from insurance companies, hospital charge-offs or family savings. Again, as I’ve said many times, Big Pharma makes more money when someone is in a hospital than they would ever receive from a single vaccine.

One of the most amusing tropes of the antivaccination cult is that somehow better sanitation eliminated vaccine preventable diseases (despite some diseases having nothing to do with sanitation). Of course here is a disease, rotavirus, that is transmitted through fecal material, and is one that improved sanitations should have theoretically eliminated. Except, 500,000 kids got sick from rotavirus, a number that has nearly been reduced by nearly 450,000 by 2011. Think about that. Nearly 450,000 children are not getting sick enough to see a physician or emergency room. And unless I’m missing some news report somewhere, there wasn’t a sudden upgrade in the sanitation infrastructure in the USA in 2007. But please, if there is, leave a comment for me, and I’ll rewrite this article!

Tara Haelle, science writer and pro-vaccine mother, wrote a blog post about Leshem et al. article, strongly emphasizing the fact this paper provided substantial evidence of the herd effect:

Put simply, fewer kids needed to be hospitalized for rotavirus EVEN IF they didn’t get the vaccine. How did that happen? Well, it wasn’t sanitation, folks. And no other major changes occurred between the five years before the vaccine and the several years after the vaccine except… the vaccine.

When enough kids were getting the vaccine, which was obviously working since hospitalizations among vaccinated kids decreased so sharply, it prevented the virus from spreading throughout the population. Vaccinated kids who weren’t getting rotavirus because they were protected ALSO weren’t passing it along to other kids, vaccinated and unvaccinated.

The kids who were unvaccinated benefited from those who got the vaccine. Meanwhile, however, those who were unvaccinated? They were the ones more likely to contract rotavirus… and therefore to pass it along to other kids.

Put simply: vaccinated kids were protecting themselves AND others. Unvaccinated kids were at risk AND putting other kids at risk.

So there you go. The vaccine reduced hospitalizations. It built a strong herd effect. The authors of the article concluded that, “our findings demonstrate the substantial and sustained decline in diarrhea-associated health care utilization and related costs in US children after rotavirus vaccine implementation.” And they provided a boatload of evidence to support that.

In the future, if you hear the trope that there is no herd immunity. How about showing them this article!

  1. Man, haven’t you Big Pharma shills been paying attention? The rotavirus rates have been dropping due to increased sanitation, and better hand washing techniques*.

    Vaccines are just Big Government’s way to control you with the nanomachines they inject into your body after the chemtrails sterilize you, and GMOs turn you into a mutant.

    *Or else switching to digital…

    1. Why did not the issues with rotavirus exist years ago? No one had even heard of it then. People who do not realize the threat to human health that GMO’s represent, have done and accepted zero independent research.

        Alright, i’ll stop taking the piss out of you. Why have you not heard of the rotavirus before now? I don’t really know. Maybe because you were too busy killing your brain cells with the garbage you linked to on youtube? Or maybe you were doing other things, and an anti-vaccine loon pointed you to this site?

        But trust me, no one is out to “get you,’ or “control you,” or anything like that. Where’s my proof? You’re still here, right? You’ve had vaccines, you’ve eaten GMO foods. And here we are.

  2. Vaccine-smaccine! The decline in rotavirus cases can really be attributed to the popularization of those little bottles of hand sanitizer 🙂

          1. I can smell the stench of endless vaccine injury denial, and as well in the refusal to accept any and all evidence at all of vaccine failure and ineffectiveness. That is all you ever have brewing in your stink pot of in denial tricks, Bray.

            1. Yes, Sabelmouse. An unhinged antivaxer that usually at HuffPo. We have bumped heads many times. I threw out moose instead of mouse to irritate her a bit.

    1. I actually think vaccines are creating a worsening situation with gut bugs and a lot more. Just like with antibiotics, pathogens of any kind are and can continually evolve to beat whatever is trying to beat it. There is not much of anything more marvelous however, than the human immune system. Apparently that is something that the CDC thinks can not function without pharma’s toxic and contaminated vaccines. Is there any point at which anything at all, Vanderweide; would become more harm than good being done?

      Rapid Increase in Pertactin-deficient Bordetella pertussis Isolates, Australia


      Acellular vaccines against Bordetella pertussis were introduced in Australia in 1997. By 2000, these vaccines had replaced whole-cell vaccines. During 2008–2012, a large outbreak of pertussis occurred. During this period, 30% (96/320) of B. pertussis isolates did not express the vaccine antigen pertactin (prn). Multiple mechanisms of prn inactivation were documented, including IS481 and IS1002 disruptions, a variation within a homopolymeric tract, and deletion of the prn gene. The mechanism of lack of expression of prn in 16 (17%) isolates could not be determined at the sequence level. These findings suggest that B. pertussis not expressing prn arose independently multiple times since 2008, rather than by expansion of a single prn-negative clone. All but 1 isolate had ptxA1, prn2, and ptxP3, the alleles representative of currently circulating strains in Australia. This pattern is consistent with continuing evolution of B. pertussis in response to vaccine selection pressure.


      Acellular pertussis vaccination enhances B. parapertussis colonization

      An acellular whooping cough vaccine actually enhances the colonization of Bordetella parapertussis in mice; pointing towards a rise in B. parapertussis incidence resulting from acellular vaccination, which may have contributed to the observed increase in whooping cough over the last decade.


      Acellular pertussis vaccines protect against disease but fail to prevent infection and transmission in a nonhuman primate model

      In that baboon study, pertussis vaccine was shown to not prevent transmission of the pertussis pathogen, in the vaccinated; even though being challenged and remaining non symptomatic. So then, how is it possible that the claim is true that vaccination protects the unvaccinated, or those that can not be vaccinated? Obviously it does not. Why did they not do that kind of a study years ago, and as well in regard to all vaccines given? You see some of the most important issues have been overlooked; and but yet you people all present with that you are the purveyors of the needed vaccine safety and effectiveness science.

      Our results demonstrate that the baboon provides an excellent model of clinical pertussis that will allow researchers to investigate pertussis pathogenesis and disease progression, evaluate currently licensed vaccines, and develop improved vaccines and therapeutics.

      Compulsory Vaccination Killed More Than Smallpox

      A short history of Smallpox Vaccine

      V. Thirty Years of Rapidly Decreasing Vaccination in Leicester, and its Teachings.


      (1) The great manufacturing town of Leicester, with nearly 200,000 inhabitants, affords the most conclusive proof of the uselessness of vaccination that it is possible to have; and the doctors and government officials carefully avoid dealing with it except to prophecy evils which have never come to pass.

      Down to 1872 Leicester was one of the most completely vaccinated towns in the kingdom, the number of vaccinations, owing to alarm after epidemics, several times exceeding the number of births. Yet in 1871, at the very height of its good vaccination record, it was attacked by the epidemic with extreme severity, its small-pox deaths during that year being more than 3,500 per million of the population, or about a thousand per million more than the mortality in London during the same epidemic. If ever a test experiment existed it is this of Leicester, where an almost completely vaccinated community suffered more than unvaccinated and terribly insanitary London, on the average of the last forty years of the eighteenth century.

      But even more conclusive evidence is to come.

      (2) That fearful mortality destroyed the faith of Leicester in vaccination. Poor and rich alike, the workers and even the municipal authorities began to refuse vaccination for their children. This refusal continued till, in 1890, instead of 95 per cent. the vaccinations reached only 5 per cent. of the births! [[p. 17]] As this ominous decrease of vaccination went on the doctors again and again prophesied against it, that once small-pox was introduced it would run through the town like wildfire and decimate the population. Yet it has been introduced again and again, but it has never spread; and from that day to this no town in the kingdom of approximately equal population has had such a very low small-pox mortality as this almost completely unvaccinated and–as the doctors say–unprotected population! Surely this completes the demonstration that vaccination, instead of preventing, increases the liability to small-pox, and that the only way to abolish the disease is to do as Leicester did, leave off vaccination altogether and devote our energies to sanitation, and the isolation of such rare cases as do occur.

      Germany: 1870-1871 Over 1,000,000 people had smallpox of which 120,000 died. 96% of these had been vaccinated.

      Philippines: 1918-1919 Smallpox epidemic resulted in 60,855 deaths. (2) with over 95% of the population vaccinated, the worst epidemic in the Philippine’s history occurred resulting in a case mortality of 65%. The highest percentage occurred in the capital Manila, the most thoroughly vaccinated place. The lowest percentage occurred in Mindanao, the least vaccinated place owing to religious prejudices. (2)

      Scotland: 1855-1875 over 9,000 children under 5 died of smallpox despite Scotland being, at that time, one of the most vaccinated countries in the world.

      1907-1919 with only a third of the children vaccinated, only 7 smallpox deaths were recorded for children under 5 years of age.

      [Thats right, the vaccine truth people were right, all along. We were mislead, and lied to. Jenner caused far more harm than good.]

      Proof that Big Pharma Doesn’t Care About Vaccine Harm

        1. Evolution? Are you claiming that evolution belongs on the playing field of understanding vaccines? Really?

          The differences between the innate and adaptive immune system although there is an important distinction between them, has little to no relevance in the said subject matter. It is people the likes of Paul Offit and sources such as Pediatrics and the CDC, that fail to make such distinctions in determining vaccine risks in overwhelming the immune system with to many vaccines.


          How Do Vaccines Work? Immune Mechanisms and Consequences

          We Want The Vaccine Facts And the Real Science, (and here it is)

          1. Evolution? Are you claiming that evolution belongs on the playing field of understanding vaccines? Really?

            This was you, Professor Korsakoff:

            “I actually think vaccines are creating a worsening situation with gut bugs and a lot more. Just like with antibiotics, pathogens of any kind are and can [sic] continually evolve to beat whatever is trying to beat it [sic].”

          2. The differences between the innate and adaptive immune system although there is an important distinction between them, has little to no relevance in the said subject matter. It is people the likes of Paul Offit and sources such as Pediatrics and the CDC, that fail to make such distinctions in determining vaccine risks in overwhelming the immune system with to many vaccines.

            So there’s a distinction, but it’s not important, which is why you’re complaining that “the likes of Paul Offit and sources such as Pediatrics and the CDC” aren’t observing the distinction. Which has no relevance.

            Got it. Now, Lodwill, do everyone a favor and demonstrate your knowledge of this distinction: explain, in your own words, how one determines serologically whether an infection is a result of primary or secondary vaccine failure.

            1. You refuse to get it Boris. I or we, were on the subject matter of the failure of pertussis vaccine and in fact what was posted recently was in regard to all vaccines. The innate verses adaptive immune system is relevant to discussions of the benefit of natural immunity verses vaccine derived immunity, which is eventually and inevitably to become of course a waning immunity and not a life time immunity. Instead of staying on topic as to discussing the failure or non failure of the pertussis or any other vaccine; you chose to attempt to distract and derail that with what I said was an irrelevant subject matter to that which was essentially on deck as the subject matter I had presented with.

              The differences between the said two types of immunity are clearly relevant to the subject matter of overloading the immune system of vaccines. The reason is that vaccines are injected directly and evade the physical epithelial barriers. Skin, mouth, nose lungs, etc. There is probably a better why of describing it, but the differences between naturally acquired immunity and vaccine derive injections hopefully resulting in immunity, as obviously and entirely different means of exposure to a pathogen. You have the article right in front of you that more than adequately describes the said differences.

              Vaccine failure is when a person develops the disease in spite of being vaccinated against it. Primary vaccine failure occurs when an organism’s immune system does not produce enough antibodies when first vaccinated. Secondary vaccine failure occurs when enough antibodies are produced immediately after the vaccination, but the levels fall over time. While antibody levels always fall over time, this would be a more rapid loss of immunity than expected for that vaccine.

              Now Otis, I mean Boris. Your name is actually and really, Boris? Look, it does not really matter how vaccine failure happens; because by either means of it happening, it still happens. For our purposes here it is actually irrelevant, because vaccine failure by any means; simply put, is still vaccine failure. Whether the vaccines worked or did not work, is the basic issue and concern. If you think there is an issue and valid point to be made in that; you just go right ahead and present with it.

          1. Apparently here you did not care to, nor to do as much as to even differentiate it the understand of the simple term, evolution; and in that is an entirely different term than if you combine the words, the evolution of adaptive immunity. You are doing nothing here but playing sick distraction games with words, and your wasting my time.

            1. Which part? The part where we agree, or the part where you’re ignoring scientific evidence in favor of moronic, asinine propaganda?

            2. Oh do yo mean in regard to those 14 to 16 considered top epidemiological studies which were done on only one vaccine and one vaccine ingredient; the MMR and Thimerosal? You mean all that terrific so called science where they said they had done and had looked at all the needed studies that were necessary to show that vaccines did not cause autism nor vaccine injury. You know, the studies they have used to now deny over 9000 filed cases for vaccine injury compensation and resulting autism. Now known the rate of diagnosis to be at least 1 in 68 with autism. That so called science, right?

              It is nothing but JUNK science, Rw. Here is the analysis and as to specifically why I conclude that, and why the entire country if they had the concern enough and the ability to be honest, should conclude that.

              Where is your vaccine safety science, Rw? You actually have nothing. Where as well are your studies on the safety of vaccine aluminum adjuvants. How about as well in regard to vaccine contamination? Is that an issue? You don’t even have a clue do you? Because all you will consider and listen to is actually just the false propaganda you and all people were fed.


              We have 16 studies already that clearly state that vaccines do not cause autism.”
              — Amy Pisani, Executive Director, Every Child By Two

              “16 studies have shown no causal association between vaccines and autism, and these
              studies carry weight in the scientific industry.”
              — Dr. Nancy Snyderman, NBC Today Show Medical Editor

              “The science is largely complete. Ten epidemiological studies have shown MMR vaccine
              doesn’t cause autism; six have shown thimerosal doesn’t cause autism.”
              — Dr. Paul Offit, “Autism’s False Prophets”


            3. You do realize you’re quoting folks that disagree with you, yes? And there are more than sixteen studies that show vaccines have nothing to do with autism?

              And let’s not forget the new studies which show autism is actually a genetic defect.

              Because I’m lazy, I’m going to post one link that will lead you to the rest of the links that disprove your (and the other loons) hypothesis that vaccines cause autism: http://www.sciencebasedmedicine.org/reference/vaccines-and-autism/#resources

            4. What the hell are you wasting my time for in replying, when all you do is ignore the information and evidence of your incorrect claims and falsely mislead assumptions?

              Where in that information link is there anyone disagreeing with what I said? In fact that document entirely and fully supports what I said.

              I have a pile of studies that show that autism is not a genetic defect. What kind of an idiot would even try to imply such a thing? So, you are telling me that a 1 in 10,000 rate of autism went to now 1 in 68 because somehow suddenly in the last 25 plus years human genetics have become faulty. How long have humans being been on the earth? And in 25 to 30 years it all went bad? Just coincidentally the same time the federal vaccine court was enacted and at the same time the major increase in now no liability for anyone vaccines and vaccine doses became a process of ever increasing numbers.

              I have already seen and read all of the typical and reply posted so called vaccine studies claiming to be a vaccine safety studies. They are all repeatedly and provably junk science, every last one of them and you are wasting my time to even bother posting such junk.

              And by the way science based is not science at all, but a repeat reference to only Gorski’s previous blog pages. What Gorski does is provide only speculation in regard to any study at all, and repeated persona and false discreditation attacks on any alternative non provaccine source on planet earth.

            5. I as well asked you directly for two types of studies that have not been done and which are critical to the issue of vaccine safety and in regard to causation of vaccine brain injury and autism. You failed to produce those as I asked. Instead all you did was present with the same old MMR and Thimerosal studies which my said and linked to your analysis for specific reasons, shows clearly to be nothing but junk science with poor study designs, and with additionally the use of unreliable data, containing obviously predetermined outcomes unsupported by the data, and as well major conflicts of interest in regard to the studies funding sources. Wake up.

            6. “Wake up”? That’s the battle cry of the deluded. Tell me something: How much time have you spent in a laboratory? How many years of your life has been spent in medicine, or other branch of science?

              Get a degree, or two in a science, and we’ll talk more. Until then, try to stay away from the idiocy sites, mmkay?

            7. Wake up R.w.; the people in the so called labs are just as dumbfounded clueless and brainwashed as to vaccine safety, as the pharma schooled doctors and pediatricians. I can shove enough real science in regard to vaccine injury and autism in front of you to last you for reading material for hours; if you actually had the courage and the honesty to review it.

              How much time have you spent doing any independent research? Obviously the answer is, zero.

              When are you going to produce for me a single study showing the safety profile of aluminum adjuvants? Where are your safety studies showing the safety profile as to giving multiple vaccines from the age of infancy to the age of 6 years old, and as well up to nine vaccines in a single visit.

              Where are your studies showing confirmation that there exists no harmful contamination nor adventitious agents remaining in vaccines after production? You do know what vaccines are made from don’t you? Howmany different types of animals and monkeys are and have been used in that vaccine production process
              Do you have any studies in regard to vaccines produced by the use of aborted feal tissue, otherwise known as human diploid tissue? I am particularly interested in that issue as to the confirmation of any long or short stand DNA etc. that is left behind in thsoe vaccines. Any related safety studies you have, go right ahead and post those now?

            8. o.o

              Mr. Hubbs, I can produce thousands of studies for you, but without the proper education, this is what you’d glean from them: “a’lskdvf’lakjsdv/fkhasdlivhjalsdfvj.”

              All of my research is independant. It’s also not done at Google U.

              Once again: Go to a university, get a science degree, and we can talk. Until then, have a nice day.
