Vaccine-autism connection debunked again

Many expectant parents are wary of all the recommended vaccines their newborns are supposed to get in the first hours, days and even the first couple of years, believing that too many vaccines too soon may increase their child's risk for autism.

A new study published in the Journal of Pediatrics Friday may put them at ease. Researchers found no association between autism and the number of vaccines a child gets in one day or during the first two years of the current vaccine schedule.

The research was led by Dr. Frank DeStefano, director of the Immunization Safety Office at the Centers for Disease Control and Prevention. Together with two colleagues, DeStefano and his team collected data on 256 children with autism spectrum disorder (ASD) and 752 children who did not have autism. The children were all born between 1994 and 1999 and were all continuously enrolled in one of three managed-care organizations through their second birthday.

The researchers not only counted how many vaccines a child was given, they also counted how many antigens within the vaccines children were exposed to over three different time periods: birth to 3 months, birth to 7 months and during the first two years. They also calculated the maximum number of antigens a child would receive over the course of a single day.

An antigen is an immune-stimulating protein found in a vaccine that prompts the body's immune system to recognize and destroy substances that contain them, according to the NIH.

Some vaccines, like Hepatitis B, only contain one antigen for this one virus. However, at the time these children were vaccinated, the typhoid vaccine had 3,000 antigens per dose and the measles, mumps, rubella (MMR) vaccine had 24.

"When we compared those roughly 250 children with ASD and the roughly 750 children who did not have ASD, we found their antigen exposure, however measured, were the same," said DeStefano. “There was no association between antigenic exposure and the development of autism."

The researchers also found no association between antigenic exposure and ASD.

Geraldine Dawson, chief science officer of the science and advocacy group Autism Speaks, called the research a "well-done study." She was not affiliated with the research.

"The big challenge that we face is the fact that we still don't understand the causes of autism - genetic or environmental," she said. "So while this answers one question parents may have, we still have many more to be addressed."

Dawson and DeStefano both believe the study should be reassuring for parents concerned about the vaccine schedule. Vocal critics have argued that children receive too many vaccines too soon, and that the frequency of the shots is one factor in why some children develop autism.

"I would tell an expectant mom that one of the more important things you can do to protect an infant's health is get them vaccinated on time according to the recommended schedule," DeStefano said. He says vaccines protect against serious life-threatening diseases and delaying them can put your child unnecessarily at risk.

"The bottom line is the number of vaccines, or the number of antigens in the current schedule, given on time ... is not associated with a risk of autism."

In 2011, the British medical journal BMJ said a now-retracted study linking autism to the vaccine that prevents measles, mumps and rubella was an "elaborate fraud" that did long-lasting damage to public health. An investigation by the journal said the study's author, Dr. Andrew Wakefield, misrepresented or altered the medical histories of all 12 patients whose cases formed the basis of the 1998 study.

Wakefield told CNN's "AC360" that his work had been "grossly distorted" and he was the target of a "ruthless, pragmatic attempt to crush any attempt to investigate valid vaccine safety concerns."

The now-discredited paper panicked parents and led to a sharp drop in the number of children getting the vaccine. Measles cases increased in the ensuing years.

    seems pretty simple. vaccines work right? what do you have to worry about from the unvaccinated crowd? tell you what, you get your kids their "livestock/herd immunities" , and this family shall not. let's see who comes out on top? cheers.

      And every time your unvaccinated kids get sick and expose a child who CAN'T be vaccinated because of an immune deficiency, that's on your head. That's why herd immunity EXISTS – to provide protection to people who can't get vaccines. You're a selfish, arrogant fool.

      Of course vaccines work. Many once dread diseases have been all but erased due to all of us getting vaccinated when we were young such as smallpox and polio. WHen you don't vaccinate you risk your kids lives and that of others who could not be vaccinated or whose vaccination, for some reason, did not provide complete immunity. They might get a less severe case if lucky but they vaccinating everyone is key. Parents who believe this nonsense when it's been disproved numerous times are idiots to risk their kids lives. There are lare areas in some states (California, for instance) where disease s are now spreading due to morons who can't think for themselves. There is NO EVIDENCE whatsoever that vaccinations cause autism! Get over it and get vaccinated!

    This whole conversation thread is laughable. Yes, drug companies pay for the studies (b/c nobody else will). Do you have any idea how many studies run by drug companies actually fail? Do you know what it takes to get any pharmaceutical product through clinical trials and onto the pharmacy shelf?

    The risk/benefit profile of approved vaccines is favorable, and that's a fact. Neglecting to vaccinate your child is only doing him/her a disservice. Take some time to read about some of the infections/conditions that can be prevented by vaccination (diphtheria, polio, tetanus, etc.), and then maybe this conversation could be fruitful.

      I work at a university that does clinical trials for drugs routinely. Studies that are funded by drug companies are usually performed by the drug companies, but later in a drug's development, the studies are done independently (i.e., only gov't or independent funding) so that the results aren't tainted by drug companies' money. Of course, the companies are interested in real results too, because they can't market a drug that isn't efficacious to at least some degree. So to totally dismiss a study that was conducted by a drug company because it was conducted by a drug company isn't a good idea either. It's often used as a baseline to conduct an independent study.

      But as a med student, you probably already knew that.

      An alternative shot schedule (a bit delayed) is sufficient for those who will have a bigger immune response to the vaccines. No need not to allow the shots, just allow them more staggered and one at a time. It's a small percentage of kids whose immune system can't handle it all, and then it causes widespread inflammation.

    Why is this news? Take a microbiology course, even community colleges offer it! To the (idiot) parents who don't vaccinate, you are selfish fools. Unvaccinated individuals serve as reservoirs for disease on a macroscale. It's the reason polio is still a threat outside first world nations. And guess what? When some individuals are vaccinated and others are not the virulence factor of the disease increases, and may even cause vaccines to fail in some cases due to the rapid mutation rate. If you want to risk your kids dying from measles, be my guest, you probably have stupid kids anyway and it will be better for everyone if your genes don't get passed on. But to risk the health of every other person on the planet because you are a moron? I mean how many of you realize the mobility of people across the globe can bring a disease from africa, china, or south america here in 24 hours? think about that for a minute. A virus has no borders, particularly measles. Immigrants from mexico and south america often are unvaccinated and form a major part of our work force for the service sector, working in sensitive areas with food preparation, processing, and even housekeeping & construction! Everyone needs to be vaccinated. If you want to worry about "government control" you are probably mildly schizophrenic! If you want to worry about autism prevention, lose some weight, stop using bpa plastics, and pay attention to real science! How lazy do you have to be when you can't even look for information on google scholar?

    One study doesn't make it a FACT. Different people react differently to medicine or vaccines, and the developers of these vaccines have no idea what side effects, or just effects, the vaccine will have on the individual later in their life. Human guinea pigs.

      Parents should ask their doctor for a full list of ingredients in the vaccine. But perhaps more importantly, mother's milk is supposed to provide all the antibodies a baby needs, so what the mother eats is far more important.

      Absolutely true, Vance. It depends on lots of factors, including any shots the mother received during or just before pregnancy. People more prone to inflammation, such as A blood types, are at a higher risk, as an example. An alternative shot schedule (a bit delayed) is sufficient for those who will have a bigger immune response to the vaccines. No need not to allow the shots, just allow them more staggered and one at a time. It's a small percentage of kids whose immune system can't handle it all, and then it causes widespread inflammation.

    If parents are able to look at the overwhelming scientific evidence of the efficacy for vaccination protocol and still determine it is not in their child's best interest, then they should not be forced into it. Though I believe this to be a grave mistake, it is not my child and I should have little control over their private health decisions. What is blatantly obvious to some may not be to others. For those who believe these individuals to be the epitome of irony and selfishness because most of them were vaccinated by their parents, take comfort in knowing nature has a way of eliminating this ignorant behavior from the gene pool. I do want to mention that since the now debunked and disgraced journal article was published in The Lancit, MMR vaccine rates have declined by as much as 50% in some areas, yet autism has continued to increase at rates approaching 700%. This is not too mention that rates of vaccination for most available vaccines have declined, many beneath the needed level for herd immunity. Nonetheless, if one factors out the scientific and medical advances allowing for better diagnosing of autism, the 700% increase rate does not correlate with the decline of vaccination rates. In fact, it runs contrary to the notion vaccines cause autism. It seems the data shows vaccines may decrease autism rates. Of course, it is not difficult to see correlation of data does not neccessarily equal causation. Then again, if everyone understood that, then this whole vaccine and autism conspiracy theory would never have reached the light of day.

      Not your child? That very well may be, but I urge you to look into immunity as it relates to a community. immunizations and vaccines only work if a specific number of the community is innoculated. Otherwise the community is still at risk, immunized or not.

      Yes, they most definitely SHOULD be forced into it, not only for their own safety, but for everyone ELSE'S safety as well. As April stated, when some people are vaccinated while others are not, it creates pockets of opportunity for a disease to flourish and mutate to the point where the existing vaccine would no longer be effective. This isn't a matter of opinion. This falls under the perview of extablished scientific fact. choosing not to vaccinate your child is tantamount to child abuse and endangerment. If you don't understand that and still want to opt out of vaccinations, kindly opt out of having kids, too

Failed to publish info on the other harmful chemicals...etc. Just a very limited study with a small group of people that they studied. Read the research results. Consider the possibilities of causation. 1 in 50 kids have autism. Your educational system can't handle that many special needs kids. There is not enough money. Figure it out.

    To all of you who think that we are neglectful by not getting the vaccines. I got the vaccines for all my children. I have four. And on the last one things went wrong. I am not being neglectful, I am trying to keep my child alive. Three days on life support. Thats what it got him. Im not saying that it is the cause for all autism, but it is the cause for some. I am also not saying that you should not get the vaccines. They are a good thing. But why to we pump so much into such little bodies at one time. Doctor has recommended NOT to get vaccine for my youngest, as it has proved life threatening. And as for my other kids, we only do one vaccine at a time. Less for the body to deal with at once, and much safer for the child. Everybody wins.

    I'm all for immunization our children. I teach Clinical Ed for a large Children's hospital. My concern with this article is that the picture you show is a child getting an intermuscular injection in the upper arm. This child is much too young to get a needle of that length in the upper arm. Why didn't you show a child getting injected in their thigh which is a much bigger muscle and is the recommended choice of the CDC. This picture is scary all in itself. A child being embraced by a parent and receiving the injection is the thigh would have been a more reassuring picture.

    This article presents a study that does not in the least prove that there is no link between vaccines and autism. The only thing it does is prove that the antigen in the vaccine was not the causative factor. How many ingredients are there in vaccines? More than just antigens. You have not done anything here except enable the pharmaceutical establishment to continue to lie to the world about the true causes of vaccine injury and many of the health problems we face – the pure poison they put in their products!

    TO say it hasn't been proven that autism is a result of vaccines is true. To say autism is not caused by vaccines is NOT true. Nowadays we know we can acquire prion diseases (like MAD COW) from a blood transfusion or medications that have blood products, just a few years ago, that was not on the product labeling. Now we are admitting that variant CJD is the same thing as CJD or MAD COW and somehow it "jumped species". This was not known when I was in medical school in 2000, but I suspected it to be true at that time. My professors adamantly told me I was wrong. One of them being the head pathologist at University of Pittsburgh. I do believe autism is caused by vaccination ( and other things as well). Not every vaccine will nor every child will get it, we don't yet know who is susceptible and or why. But we will. Lets have this conversation again in a few years, when it becomes harder to hide the truth and when dogmatic minds are a little more open to different possibilities. And please, don't call someone who makes a different choice or has a different opinion, an idiot. We should respect different opinions and recognize, this country was founded by people who were persecuted simply for that, for a different opinion.

    When my child was 3 months she was exposed to chicken pox from a non vaccinated 2 yr. old and I sought legal representation against this irresponsible parent who allowed his 2 yr. old to spread the disease to those who cannot protect themselves. That's right. We need to start holding these people who are spreading disease accountable for their irresponsible actions.

    And did you take the baby ANYWHERE else besides in contact with said 2 year old? You could just as easily have been exposed to it at Target or Walmart…

    This is misdirection. The statement should be I'd rather have a child with a strong immune system, than one potentially with Autism.
    Also another misdirection is that vaccines eliminated the deadly diseases. Lookup Raymond Obomsawin, PhD research into the actual numbers.
    Most diseases had already come down 95% from their peak before vaccines were even introduced. Sanitation and better hygiene eliminated most diseases.

    In any case, the article it seems , it only correlates total number of antigens with autism, which the alternate hypotheses arent disputing.
    Its the adjuvants, and toxicities (hg aluminium squalene formaldehyde gelatin egg protein human albumin formaldehyde phenoxyethanol msg ) in the vaccines, the multiple doses and how closely they are given, and also the Tylenol and antibiotics to mitigate the side-effects, that is in question.
    Just read the data sheet on the vaccine. Better yet read the after-market reports of the vaccine online before you decide to inject a newborn

I'm not anti-vaccine but believe we, as a society, are not fully informed about side effects and risks related to these vaccines. I encourage all of you, prior to getting a shot, to ask your RN/LPN for the drug manufacture insert and read what the pharmaceutical maker disclaims in their own product. It is very informative.

    Infants can't get the chicken pox shot.

    "Of course, they only recommend the vaccine for 12 months and up…because it must be so safe, right?"

    Ha ha ha. You are very funny. Actually, the vaccine is safe for infants, it just doesn't work, due to maternal antibodies that disappear around the 12th month of life.

    I used to disagree with Question Everything. My first child was vaccinated and seems to do OK. But my first child kept getting runny noses and coughs from playing with other children. So I felt the same way as Question Everything and I refused to vaccinate my second child and raised him in a plastic bag. He died because he couldn't breathe. I got smarter with my third child. I raised her in an aquarium with hepa filters. I protected her from all of the nasty germs out there. She has no friends and cannot leave the house. Her doctors say that her immune system never developed and is so weak that leaving her aquarium could kill her. But she hasn't been exposed to any vaccines or infectious agents, so I feel pretty good about that. I can't understand why my first child, who is doing great despite a history of getting sick occasionally, doesn't hate me for letting him grow up in such a dangerous environment. Keep preaching, "Question Everything," with our hard work, we can one day prevent all of our children from ever having to breathe the same air as other human beings.

    So what? Vaccination does NOT cause autism. Period.

    Also, in response to your concerted effort to change the topic: No one claims that vaccination is 100% effective. It is, however, far more effective than any alternative – like, for instance, contracting smallpox and hoping you live through it so you'll acquire immunity, with the head-to-toe scarring a small price to pay, I guess, in your opinion.

    Please – tell me how smallpox doesn't exist anymore and isn't a concern. You know why? Because it was wiped out by vaccination programs.

    If your child is vaccinated and still catches a disease from a non vaccinated person??? what is that saying? maybe that the vaccinations are not effective in the first place. You say that infants can not get the chicken pox shot......well why not???? it is safe, right???There is no way a person can convince me that vaccinations are not the cause of SOME types of autism.... I watched my son regress on his social skills and develop seizures a day after he was given 4 inoculations. He has now been diagnosed with autism. Medical professionals say that it is just a mere coincidence..... I think not... Maybe we should hold the medical professionals responsible for the harm that is done to SOME children's from vaccinations. Not every one will have a bad reaction from the vaccinations. They actually have saved many lives and wiped out some horrible diseases. In addition to wiping out diseases they have also taken the lives of many children. I will NEVER get my child another vaccination as it could kill him next time. I am sure if I never experienced this first hand I would think that vaccinations were safe for all kids also.. The truth is that they are safe for some kids..... but not all.
