US Court affirms thimerosal-autism connection "not...scientifically sound"

"US court rules again against vaccine-autism claims":

Vaccines that contain a mercury-based preservative called thimerosal cannot cause autism on their own, a special U.S. court ruled on Friday, dealing one more blow to parents seeking to blame vaccines for their children's illness.
As I've written before, the connection between vaccination and autism was started by a deeply flawed study created (largely out of whole cloth, it seems) by British "Dr." Andrew Wakefield. The belief that vaccines cause autism has caused significant abandonment of vaccination both in the US and in Great Britain, resulting in probable loss of herd immunity for segments of the population, especially against measles.

In the US, the case against thimerosal-caused autism is clearly shown by the continuing rise in autism diagnoses despite the removal of thimerosal from vaccines. This leaves anti-vaxers reaching for conspiracy theories rather than admit that thimerosal doesn't cause autism.

One would hope that the complete discrediting of the original "research" linking autism to vaccinations would have terminated this foolishness. Since it hasn't, I don't think this court case is going to do much good in that regard.

I wish critical thinking were taught in schools. And that lawyers who brought patently silly lawsuits based upon discredited science were severely sanctioned unless they won.

"Dr." Wakefield, vax hack, showed "callous disregard"

Britain's Dr. Andrew Wakefield, already infamous for fixing the data to demonstrate a non-existent link between autism and vaccination, has been called "irresponsible and dishonest" by the General Medical Council:

The doctor who caused a national controversy by linking children's triple MMR vaccine to autism acted unethically and dishonestly and had failed in his duties as a responsible consultant, a disciplinary panel ruled on Thursday.

The General Medical Council (GMC) also said that Andrew Wakefield had shown a "callous disregard" for the suffering of children and had brought the medical profession "into disrepute."
Ninety pages of charges were brought against Dr. Wakefield, and the GMC will further consider "whether Wakefield's behaviour amounts to serious professional misconduct, which could lead to him being struck off the medical register".

We can only hope.

Consider the Source II

This is the second in what is likely a long ongoing series of posts exhorting readers to evaluate what they read. Here's the first article.

According to NaturalNews.com, Thousands of Americans died from H1N1 even after receiving vaccine shots (free registration required for full article):
(NaturalNews) The CDC is engaged in a very clever, statistically devious spin campaign, and nearly every journalist in the mainstream media has fallen for its ploy. No one has yet reported what I'm about to reveal here.

It all started with the CDC's recent release of new statistics about swine flu fatalities, infection rates and vaccination rates. According to the CDC:

• 61 million Americans were vaccinated against swine flu (about 20% of the U.S. population). The CDC calls this a "success" even though it means 4 out of 5 people rejected the vaccines.

• 55 million people "became ill" from swine flu infections.

• 246,000 Americans were hospitalized due to swine flu infections.

• 11,160 Americans died from the swine flu.

Base on these statistics, the CDC is now desperately urging people to get vaccinated because they claim the pandemic might come back and vaccines are the best defense.

But here's the part you're NOT being told.

The CDC statistics lie by omission. They do not reveal the single most important piece of information about H1N1 vaccines: How many of the people who died from the swine flu had already been vaccinated?

Many who died had already been vaccinated

The CDC is intentionally not tracking how many of the dead were previously vaccinated. They want you (and mainstream media journalists) to mistakenly believe that ZERO deaths occurred in those who were vaccinated. But this is blatantly false. Being vaccinated against H1N1 swine flu offers absolutely no reduction in mortality from swine flu infections. [1]

And that means roughly 20% of the 11,160 Americans who died from the swine flu were probably already vaccinated against swine flu. That comes to around 2,200 deaths in people who were vaccinated! [2]

How do I know that swine flu vaccines don't reduce infection mortality? Because I've looked through all the randomized, double-blind, placebo-controlled clinical trials that have ever been conducted on H1N1 vaccines. It didn't take me very long, because the number of such clinical trials is ZERO. [3]

That's right: There is not a single shred of evidence in existence today that scientifically supports the myth that H1N1 vaccines reduce mortality from H1N1 infections. The best evidence I can find on vaccines that target seasonal flu indicates a maximum mortality reduction effect of somewhere around 1% of those who are vaccinated. The other 99% have the same mortality rate as people who were not vaccinated. [4]

So let's give the recent H1N1 vaccines the benefit of the doubt and let's imagine that they work just as well as other flu vaccines. That means they would reduce the mortality rate by 1%. So out of the 2,200 deaths that took place in 2009 in people who were already vaccinated, the vaccine potentially may have saved 22 people. [5]

[1] Strong assertions require strong evidence. As we see, there will be no such evidence provided.

[2] Numbers follow from the assertions above, but those assertions are still baseless.

[3] Concluding that there is no effect because he has read no studies (or even because no studies exist) falls under the category of "absence of evidence is not evidence of absence."

[4] Wikipedia summary on effectiveness of flu vaccines. I am not qualified to judge the relative goodness of scientific studies, but I note that this article cites peer-reviewed work from The Journal of Infectious Diseases, Vaccine, JAMA, and The Lancet. Against an unsupported assertion that studies show, at most, a 1% reduction in mortality, I'll take the peer-reviewed journals, or even the New York Times. For example:
In a new study reported at Wednesday’s meeting, Dr. David K. Shay, who led a team from the C.D.C. and eight state health departments, found that full immunization against flu provided about a 75 percent effectiveness rate in preventing hospitalizations from influenza complications in the 2005-6 and 2006-7 influenza seasons. (The 75 percent rate could range, according to a standard statistical measure known as confidence intervals, from 41 percent to 91 percent.)
The assertion of a 1% reduction in mortality is not necessarily orthogonal to a 41-91% reduction in hospitalizations. The claim of 1% (mortality reduction) is intended to say "vaccination is not useful". The claim of 41-91% (hospitalization reduction) would invalidate that.

[5] The math is fine. The assumptions, as listed above, are suspect, at least.

I could go on. The gist of it is that this inflammatory article sets up straw men, assumes a lot (everything, it seems), draws conclusions based upon assertions which appear to be in conflict with peer-reviewed research, asserts intention behind acts of omission or commission, and generally ignores science, statistics, and logic in favor of repetition, unsupported assertion, straw men, passion, inflammatory statements, and righteousness.

I love this quote:
Through its release of misleading statistics, the CDC wants everyone to believe that all of the people who died from H1N1 never received the H1N1 vaccine. That's the implied mythology behind the release of their statistics. And yet they never come right out and say it, do they? They never say, "None of these deaths occurred in patients who had been vaccinated against H1N1."
Of course they don't say that. Nobody in the scientific community would ever claim that vaccination is 100% protection. Vaccination is a way of engaging the immune system, bolstering our natural ability to resist disease. Ideally, vaccination is a way of engaging the immune system of the population, so that the disease does not become epidemic.

Followed up with:
So they just gloss over the point and imply that vaccines offer absolute protection against H1N1 infections. But even the CDC's own scientists know that's complete bunk. Outright quackery. No vaccine is 100% effective. In fact, when it comes to influenza, no vaccine is even 10% effective at reducing mortality. There's not even a vaccine that's 5% effective. And there's never been a single shred of credible scientific information that says a flu vaccine is even 1% effective.
A wonderful straw man argument: they don't claim 100% effectiveness, so it's suspicious that they don't achieve it! Alongside assertions about lack of effectiveness in reducing mortality, ignoring the peer-reviewed evidence that flu vaccines provide a great deal of reduction in hospitalization -- clearly a benefit, and likely indicative of a reduction in mortality (unless everyone who dies of the flu does so outside the hospital).

The hits just keep on coming. Go ahead and read the whole thing, if you must. I'd like to call out one more thing, though. The author proudly notes "Sources for this story include" CNN and the Washington Post. But neither of those articles has anything to say about vaccine effectiveness. The author is counting on you not following those links, but just assuming the authority of CNN and the WaPo to convince you that the views in the article are mainstream.

They're not.

I don't know anything about naturalnews.com -- or at least I didn't until I read this article. Now I know that I'm not particularly interested in what they have to say.

Autism / Vaccination Link Based Upon "Fixed Data"

(Photo: Child with Measles, Source: Allergy and Asthma Source, Rise in Numbers of Unvaccinated People Lead to Measles Outbreak)

The modern myth that "vaccines cause autism" was started by the February 1998 publication of a study by Andrew Wakefield in The Lancet. According to The Sunday Times:

Confidential medical documents and interviews with witnesses have established that Andrew Wakefield manipulated patients’ data, which triggered fears that the MMR triple vaccine to protect against measles, mumps and rubella was linked to the condition.

The research was published in February 1998 in an article in The Lancet medical journal. It claimed that the families of eight out of 12 children attending a routine clinic at the hospital had blamed MMR for their autism, and said that problems came on within days of the jab.

The suggestion that there might be a link between vaccination and autism has resulted in a 12% drop in vaccination in the UK (from 92% to 80%), with an attendant 24x increase in confirmed measles cases in England and Wales (from 56 in 1998 to 1348 in 2008).

It turns out, however, that there appears to have been serious misconduct involved in the study's publication. Also from The Sunday Times:

However, our investigation, confirmed by evidence presented to the General Medical Council (GMC), reveals that: In most of the 12 cases, the children's ailments as described in The Lacent were different from their hospital and GP records. Although the research paper claimed that problems came on within days of the jab, in only one case did medical records suggest this was true, and in many of the cases medical concerns had been raised before the children were vaccinated.

There are also allegations that the children selected for the study were selected by, and the study paid for by, lawyers who were already pursuing litigation against vaccine companies.

What Wakefield seems to have done is not just dishonest -- he is apparently individually responsible for dropping the UK 15% below the threshold for total herd immunity (95%). If the allegations against him are true, he's personally responsible for thousands of cases of measles and some unknown numbers of deaths.

Any sensible person who knew the limitations of Wakefield's study would know that there was nothing to the alleged link between vaccination and autism: a single unblinded study of 12 individuals would be highly suspect even if the selection process wasn't subverted by lawyers. But thousands of parents have taken to heart the false idea that vaccination causes autism, and as a result thousands of children are unvaccinated, thousands have gotten measles, and undoubtedly some have died. Millions of dollars have been spent to disprove Wakefield's alleged "link".

Shame on you, Dr. Wakefield. You deserve everything that's coming at you.
