Vaccines don't cause autism


Vaccines are generally considered to be the most successful public health intervention ever devised. And yet there have been opponents of vaccines ever since there have been vaccines. So-called antivaccinationists have claimed over the years that vaccines do not work, despite the overwhelming evidence that they do. They often spread misinformation about vaccine, such as the notion that vaccines weaken the immune system, when in fact they work by strengthening the immune response against the target infection.

In recent years the antivaccine movement has focused on the claim that vaccines are linked to neurological injury, and specifically to the neurological disorder autism, now referred to as autism spectrum disorder (ASD). However the scientific evidence overwhelmingly shows no correlation between vaccines in general, the MMR vaccine specifically, or thimerosal (a mercury-based preservative) in vaccines with ASD or other neurodevelopmental disorders.

The primary argument made for an association between thimerosal and ASD is that the rate of diagnosis of ASD has been steadily increasing since the early 1990s. At that time also the routine vaccine schedule was increasing, resulting in an increasing total dose of thimerosal. The antivaccinationists then assume causation from correlation to blame rising ASD rates on thimerosal.

However, by 2002 thimerosal was completely removed from the routine vaccine schedule, and now remains only in some flu vaccines. The total dose of thimerosal exposure is far below 1990 levels, before ASD diagnoses began to rise. Antivaccinationists predicted that ASD rates would fall dramatically in the years following the removal of thimerosal from most vaccines – but rates have continued to rise without even the slightest change in the rate of increase. This is a powerful refutation of the thimerosal-autism hypothesis, and has been replicated in other countries.

Further, the best epidemiological evidence suggests that the rise in the diagnosis rate of ASD is an artifact of broadening the definition of autism, diagnostic substitution, and increased surveillance. Therefore there isn’t really an autism “epidemic” just a change in the definition and efforts to make the diagnosis.

Undaunted, the antivaccinationists have changed their claims to blame any number of “toxins” in vaccines. However, their claims have no scientific validity.

if the above two statements are true - why then did you write THIS comment???

Why remove it, if it's safe?

Riddle me that.

reply

It was a precautionary measure. Those might turn out to have been necessary, or not (as in this case). The concerns where raised (as I understood it) because of the (more) damaging properties of methylmercury so they wanted to have a closer look at ethylmercury as well. And since now there is no thiomersal in the vaccines (apart from the flu vaccine) and some vaccines never contained it, how is ist causing autism today?

Now they say it's the aluminum, which is a perfect example of the "moving the goalposts" fallacy.

The source did not say. Perhaps a better solution was found? Perhaps the public hysteria about the tiny dose of mercury, much less than a tuna sandwich, motivated a change? Perhaps the tiny dose of mercury was suspected of having some other side effect, or was simply seen as a suboptimal solution?

Of course, the mercury compound was added because of famous cases where vaccines became contaminated with bacteria and children died. Those cases were from decades ago, when hypodermic needles were used to draw repeated doses from the same vial of vaccine. Today, almost every vaccine is distributed in single-use needles, presumably reducing or eliminating the risk of contamination, and perhaps reducing the need for the mercury compound.

Just speculating, but you asked.

Also the mercury-containing compound in fish is different from the one in the vaccines. More dangerous also. It is similar enought that concerns were raised and it was checked but to me it looks like there is nothing to it.

A. Of course, the mercury compound was added because of famous cases where vaccines became contaminated with bacteria and children died. Those cases were from decades ago, when hypodermic needles were used to draw repeated doses from the same vial of vaccine.

C. and perhaps reducing the need for the mercury compound.

Yes I did ask. Your answers are - as you said - "speculations." {BTW - The numberings and letterings are mine.}
So:
#1. "a better solution was found"
If it ain't broke why fix it? The vaccines were deemed to be SAFE.
#2. "public hysteria"
Is this like the public hysteria over MSG or HFCS or artificial sweeteners or etc added to foods? Where even though the FDA considers them as GRAS, GRASsroots folks do not - and eventually advertisers start advertising "NO MSG ADDED" "NO HFCS" and Even the FDA is coerced unhappily to remove one or another other formerly GRAS ingredient?
#3. "Perhaps the tiny dose of mercury was suspected of having some other side effect"
That is quite a suspicion. What could that "other side effect" be?
And again, if the vaccine was 100% safe why would there be any suspicions at all? They've checked them, they've re-checked them, the FDA has approved them, The CDC has has approved them, the WHO has approved them, the Govt has approved them so much so that parents are FORCED to innoculate their kids.
#4. "or was simply seen as a suboptimal solution"
Like I wrote before - If ain't broke....
A lot of songs are written with the lyrics: "I wouldn't change a thing about you" "You're perfect just the way you are" etc etc.
So why mess with a perfect thing?

A. I had heard but didn't really know of The "famous cases....where children died" because of contamination. Can you give me a link or info to these famous cases? "Decades ago" can be a little as 20 years ago (1986 or thereabouts?) Is this in the USA?
I DID know of the literally nearly millions of Africans who died because of contamination and re-use of syringes.
B. "Today, almost every vaccine is distributed in single-use needles," presumably reducing .... the risk of contamination"
"Almosts" and "Presumably(s)" are not what a consumer wants to hear
C. "and perhaps reducing the need for the mercury compound"
If they're 100% safe - why mess with the folks who sell you the mercury? For the billions of syringes distributed, fer sure the mercury folks would be losing a tidy sum of money.

But then again, they still keep the Mercury in Flu Vaccines. Now that is going to be a big big moneymaker.
Think ZIKA.
And Is it not still in GARDASIL? (Sorry my bad, ALUMINUM is.) And Aluminum is nearly as safe as Mercury - n'est-ce pas?

#1. "similar enough that concerns were raised"?
Who raised these concerns? When? It was distributed and verified safe and THEN there were concerns? Who raised the concerns?
#2. "and it was checked"
checked by whom? and exactly why - if it was 100% safe???
#3. "to me it looks like there is nothing to it"

That's what you wrote. I bolded the sentence.

None of the above.
When one gives an opinion about anything, that's what it is: merely an opinion. If the scientist/researcher who did the actual checking said: "to me it looks like there is nothing to it." I would ask the same thing: Who Are You?
There either is something to it.
Or there is nothing to it.
It's an either/or.
Not a maybe.
Not a "to me it looks like."

Ok, then there is nothing to it.
Even though I don't really get what is the problem with the phrase "to me it looks like it". That is how it looks like, to me. Maybe I am mistaken, mercury toxicity is not really my area of expertise, but from the data I looked at that is my conclusion.

reply

There are 3 glasses of what "looks" like water on a table a short distance from you.
#1. vodka
#2. hydrochloric acid
#3. distilled water with a drop of deadly poison in it (odorless & tasteless)

The rules:
You can't touch them
You can't smell them
You can only "look"

Are they all water?

Obviously having a "look" is important.
But checking each and coming to a definite conclusion is easily verifiable.

It is similar enought that concerns were raised and it was checked but to me it looks like there is nothing to it.


That's the problem I have with
"to me it looks like" there is nothing to it.

If you pick #1 - you can smell it.
If you pick #2 - you can "feel" the difference
If you pick #3 - Would you drink it?

reply

Ok very nice. I will smell and touch my research more in the future, looking is not enough ^^
This is what happened (as I understood it).
The safe exposure guidelines for methylmercury had been changed not long before (lowered) and new vaccines had been introduced so a situation developed in which some children, depending on the specific vaccines and the body weight, could be exposed to a higher dose of ethylmercury than what was considered safe for methylmercury. As a precaution the amount of ethylmercury was reduced. While the names sure sound similar, the pharmakokinetics are very different. Ethylmercury has a much shorter half-life and is actively secreted and does not accumulate in the body like methylmercury does. So they were cautious in case the ethylmercury has the same behaviour as the methylmercury (which it doesn't).
Also data had been available at that time, showing no ill-effects of thiomersal exposure and ethylmercury toxicity needs doses around 100x higher than what you can get from vaccines. So ,of course, eventually also ethylmercury will have negative effects but so would pretty much everything.
So I don't see the big problem and I don't consider the reduction of thiomersal as an admission that it had negative effects.

One would have to determine that the brain is not part of the body for your statement to be correct. Is that your contention? That the brain is not part of the body?

Ethylmercury hydroxide, like its cousin methylmercury hydroxide, enters the brain very easily, but once within the brain it is rapidly de-ethylated, forming tissue-retained inorganic mercury (Hg2+) species [114]. There is evidence that this “inorganic” mercury is significantly more neurotoxic than the organic mercury compounds from which it forms and more difficult to remove. Studies using monkeys demonstrated that ionic mercury is redistributed in the brain [115]. These same series of studies also demonstrated that there was extensive microglial activation in the monkey’s brain that persisted over 6 months after the mercury dosing was stopped. Thus, when the plasma mercury disappears, the brain mercury remains [116].

The preceding facts are important to remember when vaccine safety promoters tout findings of new studies showing that ethylmercury (in Thimerosal) disappears from the blood within several days. Actually, the mercury leaves the plasma and enters the brain, where it is de-ethylated and, based on human post-mortem research [174], remains with a half-life of about two decades. What is also conveniently hidden are the results of recent studies demonstrating that, within a short time, on average only about 7% of the methylmercury hydroxide administered orally was converted into brain-retained “inorganic” mercury; whereas 34% of the Thimerosal (ethylmercury compound) injected was similarly converted [117]. [Note: The value for “organic” mercury is calculated as the difference between the “total” mercury value and the “inorganic” mercury value based on sub-sample assays from a given homogenized sample. The two mercury assay procedures, “total” and “inorganic” only differ by the severity of the oxidation step used to liberate the mercury species – where the work-up for a “total” mercury determination is done under more severe conditions.] This means that a greater quantity of a more destructive form of mercury is retained in the brain following administration of a Thimerosal-containing vaccine than from the methylmercury compounds present in fish.

The famous case I recalled was in Australia in 1928. 12 children died after injections from one contaminated vial.

 Entropy ain't what it used to be.

reply

There were others, by the way. That was the famous one I recalled.

Hence a mercury compound was added to many vaccines to prevent bacteria contamination. It has since been removed from many vaccines. I don't know if they replaced it with something else or just decided that today's single-use injections do not need it because the contamination risk is low anyway.

Thimerosal is a preservative. In western countries where refrigeration and adherence to use-by dates thimerosal was not used. In the USA it was used apparently because it could not be guaranteed to the satisfaction of insurers that in some clinics refrigeration and use-by-dates would be observed so thimerosal was added.
Whatever, much research around the world using millions of children (not just in the US with the CDC) has shown zero correlation between vaccination and autism, both with and without thimerosal preservative.

So-called by whom? What are their names? Has anyone actually claimed that all vaccines are ineffective?

Antivaccinationists predicted that ASD rates would fall dramatically in the years following the removal of thimerosal from most vaccines


Again, please name names? Who made such claims?

How many petitions have been awarded compensation?

According to the CDC, from 2006 to 2014 over 2.5 billion doses of covered vaccines were distributed in the U.S. For petitions filed in this time period, 3,521 petitions were adjudicated by the Court, and of those 2,248 were compensated. This means for every 1 million doses of vaccine that were distributed, 1 individual was compensated.

Since 1988, over 17,184 petitions have been filed with the VICP. Over that 27 year time period, 14,719
petitions have been adjudicated, with 4,804 of those determined to be compensable, while 9,915 were dismissed. Total compensation paid over the life of the program is approximately $3.4 billion.

From the HHS Vaccine Injury Compensation Data. And these are just payments to the ones who come forward.
