  • Study compares vaccinated and unvaccinated populations

    Joseph Mercola, DO, has a massive emailing list about health issues. He has recently taken up the vaccine question, which I am very happy about. He has a new posting in which he interviews a pediatrician, Larry Palevsky, who regrets having vaccinated children after carefully reviewing the science involved:  http://articles.mercola.com/sites/articles/archive/2009/11/14/Expert-Pediatrician-Exposes-Vaccine-Myths.aspx

    In the posting, Mercola brings up a favorite topic of mine: that new research should compare vaccinated and unvaccinated populations, in order to understand possible adverse effects of vaccines. Seems like a no-brainer, but it isn’t happening, possibly because the medical establishment is full of conflicts of interest.  Mercola found a study that did in fact compare vaccinated and non-vaccinated populations–not for autism, but for allergies, asthma, eczema, and hay fever. This study, published in the Journal of Allergy and Clinical Immunology in April 2005, found statistically significant increases in the number of cases of these conditions in the vaccinated and partly-vaccinated groups as opposed to the never-vaccinated groups, according to Mercola. The researchers were puzzled, because they had been told vaccines were safe.


    I have been calling for research comparing vaccinated and unvaccinated groups, looking at incidence of autism.  Others are too. Since this isn’t happening with the medical establishment, a parents’ group is stepping in to fill the void. The National Vaccine Information Center has gathered $100,000 so far for some unbiased research, said Mercola.  I am very happy to hear this.

    Also in this newsletter, Mercola draws a bead on the concept of herd immunity, which the vaccine proponents cite as the reason for vaccinations.  If most of the population has been vaccinated, the virus is likely to be stopped in its tracks, according to this theory. Go below an unknown percentage, and the likelihood of disease occurrence increases.

    Pediatrician Larry Palevsky, interviewed by Mercola, pointed out that the virus doesn’t actually go away if the population is mostly immunized. It’s still there, in our bodies and our environments, but the vaccinated people aren’t (supposed to be) reacting to it.  So since it’s still there, the virus can hardly be stopped in its tracks for those who aren’t vaccinated. There is no herd immunity, Palevsky maintains.

    Interesting!! I recommend you read this posting from Mercola and sign up for his newsletter.

    I don't trust vaccinations really. Too much bad news is coming out about it.

  • tracezilla@lovelyish

    I don't mind vaccinations at all. I think that they can be quite helpful, and any risk is outweighed by the benefits. However, that's not to say that I think this about ALL vaccinations. After they've gone through enough testing and whatnot, then I trust them. So, naturally, the ones that have been in use for decades or more, I trust more than newer ones.

    I can't say that I trust the H1N1 vaccine at all, nor do I trust the vaccination out for cervical cancer. These were not tested long enough before being distributed, and we're already seeing terrible side-effects from the one for cervical cancer because people were too overzealous in getting it out to the public.

    I don't necessarily believe in the conspiracy theories about vaccines (where the adverse affects some people have are given to us on purpose), but I can see where the logic comes from that some people draw such conclusions. I just don't buy it, myself.

    Either way, I know a lot of people seem to balk at having tests like this done. And I don't mean the people making/distributing the vaccines. I mean, just regular people who support vaccination. Its as if any testing like this is a waste of time and so shouldn't be done. Well, a lot of things were first touted as a waste of time before they were finally discovered to have merit. If the money is there and the willingness is there, why not? What's there to be afraid of?

    Doing tests like this is a good idea. I'm all for vaccinations (for some things), but that doesn't mean I feel that tests like this shouldn't occur. Its good to know such answers! :p

    To clarify what I mean about vaccinations for some things, I just think we should vaccinate people for really "bad" things. Stuff that is more annoyance than anything and that we can endure easily without dying (except in the rare case, because even in rare cases an otherwise healthy person can die from the common cold if there are complications or it turns into something suddenly worse), then we probably shouldn't bother vaccinating against it in countries like the US.

    Such as chicken pox. I didn't get that vaccine when I was a kid, and I got the chicken pox when I was 9. Ugh, I still remember it, it was terrible! A lot of other kids in the school got it, too, but I don't think I was the origin of it. I think a teacher's son was the origin of it. She sent him to school even though she KNEW he had the chicken pox, and was irritated with my mother for not sending me to school. She insisted that there was no reason for my mother to keep me out of school and it was not beneficial for mother to do so, and boasted that she knew for a fact because she sent her son to school with the chicken pox on purpose. And she was a teacher!

    Either way, the majority of kids don't die from the chicken pox (although the older you are when you get it, the worse it is for you, I've heard). That isn't to say no one dies of the chicken pox in the US, and certainly people would be more likely to die from it in some places, like certain areas of Africa.

    So, I feel that there are some things that in countries like the US, the majority of people do not need to be vaccinated against. Yes, they may very likely contract the virus they aren't vaccinated against, but they won't die from it and its really more of an annoyance than anything else. Its inconvenient for everyone in the household when a kid has chicken pox, but for the majority it isn't deadly.

    But, the viruses and diseases that are still more likely to kill the majority of those who get it should probably still be vaccinated against if we have a vaccine for them.

    I just don't see the point in vaccinating for things that are just inconvenient instead of actually dangerous anymore.

    By Palevsky's argument, smallpox should still be around in the general population. You should have no problem finding smallpox in every person in the US. See how ridiculous this sounds?

    We may not be able to stop an initial infection, but once the immune system is able to recognize the invaders it makes it easier every time the virus appears; thus, the person is less likely to exhibit the symptoms (and thus less likely to transmit the virus) since the immune system is already containing the threat.

    Please learn about what herd immunity entails (as well as the interesting mathematics behind the concept) before blindly following what any random person says just because they agree with your presuppositions.

    Food for thought:

    @tracezilla@lovelyish - I think you should read this about whether or not a child is likely to get measles in the US, how measles is spread in the US and the death rate http://www.childrenshospital.org/clinicalservices/Site1884/mainpageS1884P13.html. It isn't such good news.


    It is true that just about everyone I knew had measles, mumps and chickenpox when we were young and all of us survived, although quite a few people had complications caused by measles and mumps.  The boys, including my brother, had severe testicular involvement which was agonising and several of us had terrible earaches and temporary deafness from mumps. I wouldn't want to put my children through this kind of misery if I could avoid it and I wouldn't count on them not getting the diseases if more and more people are not vaccinated and more and more immigrants come in to the country and also more people travel abroad. We do not live in hermetically-sealed bubbles!
  • tracezilla@lovelyish

    @SavonDuJour@xanga - I don't think I mentioned a single thing about measles.

  • SavonDuJour@xanga

    @tracezilla@lovelyish - True, you didn't, but I thought you were extending your remarks to vaccinations in general. I apologise for jumping to conclusions.  


    I don't have the reference handy and I'm in work now, but if you look up varicella disease (chickenpox) you will see the same situation as with measles - how it gets into populations from abroad and how since vaccination for it have been available the death rate of people without any previous illness or complicating factor has gone down from 150 a year (1994 I think) to 8 in 2007!
  • tracezilla@lovelyish

    @SavonDuJour@xanga - Oh, no problem. :p It just confused me when I didn't mention anything about measles why you were directing the link to me. Sorry!

    I definitely know that chicken pox can cause terrible problems with some people (especially if you don't get it as a child and instead you get it later in life. The older you are, the worse it effects you). However, I wouldn't think the majority would suffer from such issues, since the majority (as far as I know) are children and even if you get it there are things that doctors can do to ease issues with it.

    I would never think that you would eradicate a disease by vaccinating and then suddenly decide that since its gone it would be safe to stop vaccinating. Naturally, I realize that if you stop vaccinating for things, such as chicken pox, that more people will end up getting chicken pox. I just think that for the majority it isn't necessary to be scared of getting chicken pox. :p

    But, I will read your link on measles and I will look up vericella disease. :) I'm always open to reading and learning.

    @tracezilla@lovelyish -   You are a very bright and honest person.  It is wonderful to see someone who looks at both sides of the issue and also who looks into each individual vaccine and disease on it's own.  It would be wonderful if everyone looked at the matter in such a responsible and thoughtful manner.  Kudos to you!!!!

    @tracezilla@lovelyish - I'm glad you're keeping an open mind about the vaccination issue.  Although I'm in full support of most of the childhood vaccines, the pros and cons of having them should be clearly presented to parents (something that isn't always done).  However, just as a sidenote - the chicken pox virus, although it now rarely kills in children, isn't just a harmless pathogen.  Once you get chicken pox, the virus remains dormant in your nerve cells for the remainder of your life and can erupt later as shingles.  There are approximately 2.5 cases of shingles per 1000 people between the ages of 25 - 50 and the percentage increases as the age range increases (by one estimate, about 1 million people in the US get shingles every year).  I had chicken pox when I was about 3 or 4, and I don't remember it at all.  However last year, I developed fairly bad case of shingles on the nerves in my right arm, and I was in quite a bit of pain for about a month.  I took 6-8 ibuprofen (or Advil) everyday and even then, I could barely use my right arm and hand.  Fortunately my rash was fairly minor, but for more serious cases the shingles rash can become so severe that portions of the skin start to die and peel off. For people who are immunocompromised (i.e. seniors, HIV-positive, people on chemotherapy, etc.), the lesions can facilitate infection by more serious illnesses and cause death (just like Christopher Reeves and bedsores).

  • tracezilla@lovelyish

    @prettyruby@xanga - Actually, I'm very aware of Shingles and what causes and who is at risk for it. My father got Shingles when he got cancer and went on chemotherapy. I thought it was common knowledge that once you get chicken pox, even after it goes away you still "have it" in your body and it could come back at any point. It can actually resurface as just chicken pox again at a later date, which happened to my friend. Her doctor told her that is what happened and that it could have been due to her overstressing about a lot of things. I thought it was also common knowledge that having chicken pox also puts you at risk for shingles later in life.

    A lot of things I think are common knowledge appear to end up not being so. :(

  • prettyruby@xanga

    @tracezilla@lovelyish - Ah I see.  Sorry for the confusion - I just thought you weren't aware because of your previous comments about the chickenpox vaccine.  Thank you for taking the time to respond! :)

  • tracezilla@lovelyish

    @prettyruby@xanga - Oh, its okay. :p I think I confuse a lot of people with the way I word things. Even my own family members, when I'm speaking and not typing, sometimes either get mixed messages or completely opposite messages from what I'm trying to say. And I'm just left wondering what I said wrong to make them draw conclusions like that. :p

    At least online its usually fairly minor. I think its because I have time to think about what I'm going to say and how I'll word it (and correct mistakes I notice in the wording and whatnot) beforehand. :p

  • lonelywanderer2@xanga
  • P1AutismMom

    @tracezilla@lovelyish -  I love your assessment of "common knowledge"  This along with common sense are becoming increasingly rare in the general population.   


    Your wording is not confusing to me at all.  I believe you are expressing yourself quite well.  :)

  • Liquid_Pain_523@xanga

    The problem with doing this is the amount of confounding factors. Socioeconomic status (poor people are less likely to get vaccinations due to inability to pay for them), race (minorities, especially African-Americans, are less likely to trust the medical community, and are therefore less likely to get vaccinations), and other factors can shift the results in one direction or another. So we don't know if these factors are decreasing (or increasing) the prevalence autism because they haven't gotten vaccines, or whether those factors directly or indirectly affect the prevalence of autism themselves. So you really have to know a lot about autism, vaccines, and other things in order to do this study correctly.

    Unfortunately, I couldn't read the article due to it wanting me to register for some reason, so I can't say much about that. I wish I could have though. It looks interesting. I just hope it's good science.

  • tunatacosryumi@xanga

    @prettyruby@xanga - My younger sister got shingles at age 7 in a . . . let's say a reeeeally uncomfortable area. The doctors said most people who develop shingles aren't usually that young, but probably came as a result of her chicken pox vaccine. My older sister and I had chicken pox just before she was born and never had the vaccine. Still, from what she told me, it was really unpleasant. I don't look forward to my later years if shingles is in the future. :/
