Mike Adams is a Dangerous Loon

Where do I even begin? Mike Adams, the self-proclaimed “healthranger” who runs the crank alt-med site naturalnews, has sunk to a new low, even though he was already scraping bottom.

Adams combines the worst CAM propaganda with a blend of conspiracy theories from across the spectrum, while selling supplements and other nonsense. He portrays himself as someone who is engaged in a righteous battle against the forces of evil – so hardly someone who is engaged in rational discourse.

In a recent rant, however, he has become a parody even of himself. This time he is raving about Monsanto and GMOs, writing:

Monsanto is widely recognize (sic) as the most hated and most evil corporation on the planet. Even so, several internet-based media websites are now marching to Monsanto’s orders, promoting GMOs and pursuing defamatory character assassination tactics against anyone who opposes GMOs, hoping to silence their important voices.

Vaccine Safety Systematic Review

A new systematic review of adverse events from vaccines used in the US was recently published in the journal Pediatrics: Safety of Vaccines Used for Routine Immunization of US Children: A Systematic Review. (Full text pdf) This systematic review is actually an update and expansion to the 2011 Institute of Medicine (IOM) report on vaccine side effects.

The review looked at the best evidence available, active surveillance studies with controls, identifying 67 relevant studies. Overall they found that vaccines were very safe. There were a few associations with serious adverse events, but these were all very rare. From their conclusions:

Our findings may allay some patient, caregiver, and health care provider concerns. Strength of evidence is high that MMR vaccine is not associated with the onset of autism in children; this conclusion supports findings of all previous reviews on the topic. There is also high-strength evidence that MMR, DTaP, Td, Hib, and hepatitis B vaccines are not associated with childhood leukemia.

Evidence was found for an association of several serious AEs with vaccines; however, these events were extremely rare: absolute risk is low. For example, strength of evidence is moderate for association of vaccines against rotavirus with intussusception. Although 1 large US epidemiologic study found no association, a recent analysis of the US PRISM program found both RotaTeq and Rotarix associated with intussusception in the short term. Estimated rates were 1.1 to 1.5 cases per 100 000 doses of RotaTeq and 5.1 cases per 100 000 doses of Rotarix.

So a few vaccines are associated with rare AEs. Given the rhetoric of the anti-vaccine movement, there are a few points worth emphasizing here.

Moms for Pseudoscience – Roundup Edition

Published by under General Science

I really resent groups that transparently try to take the moral high ground, or appropriate an entire category of people, to bolster their personal ideology. The Thinking Moms Revolution (TMR) is one such group. Sorry, you don’t speak for moms, and your group is certainly not based on thoughtfullness.

A recent blog post in the HuffPo is clear pro-organic propaganda, borrowing the “mom” meme from TMR and another such group, Moms Across America. The theme of the blog is that glyphosate, the active ingredient in the herbicide Roundup, is a horrible toxin that is destroying our health, but luckily these plucky moms are going to take on the EPA and demand safety for our children (because the EPA obviously can’t do their job without help from non-scientist ideologues).

I went through a couple of overloaded irony meters reading the post, especially with this section: “Swaying Decision Makers With Science.” The article, rather, is a series of anecdotes, misrepresentations, and cherry-picked factoids masquerading as science for the purpose of ideological advocacy. No, eating organic is not going to cure your child of autism.

Measles Coming Back

There are some topics I just have to revisit from time to time. I consider this a public service announcement. So far this year there have been 288 confirmed cases of measles. This is the largest number of cases since endemic measles was declared eliminated from the US. The previous worse year was 2011, which saw 220 cases total. 

There is no question that this is tied to vaccine non-compliance. The anti-vaccine movement is scaring people with misinformation and pseudoscience into not vaccinating their children, and as a result we are seeing the return of vaccine-preventable diseases.

When a disease is endemic that means there is a self-sustaining infection – there is always someone infected somewhere and it keeps getting passed around. The MMR vaccine (especially after the second dose was added) resulted in herd immunity, which is a high enough immunity rate so that the infectious disease cannot be passed around indefinitely. High vaccination rates in the US resulted in eliminated measles as an endemic disease by 2000.

CIA Ends Vaccine Cover

The White House has announced that in August of 2013 CIA policy banned the use of vaccination programs as cover for CIA ops. Thus, hopefully, ends a blatantly unethical policy.

Back in 2011, the CIA suspected that they had located Osama Bin Laden in a compound in Abbottabad, Pakistan. They needed to confirm his presence, however. So they created a fake vaccine drive. They enlisted the help of a local physician and health official, Shakil Afridi, who set up a program to give free hepatitis B vaccines (all funded by the CIA). The goal of the vaccine program was to procure DNA from children in the compound to see if they were related to Bin Laden, thus confirming his presence.

The ploy worked, and as you probably know, Bin Laden’s compound was raided and he was summarily executed.

Synthetic Yeast

Published by under General Science

Synthetic biology is an emerging field with incredible potential. The idea is to build genomes from the ground up. Craig Venter made the first breakthrough in synthetic biology four years ago when his team created the first artificial bacterial genome. Now another team has made similar progress with yeast, which is eukaryotic (meaning the cells keep their DNA in a nucleus).

To be clear, these teams have not made life entirely from scratch, not even the genome. In Venter’s case he started with an existing bacterium, and then recreated its genome with some changes, and inserted it into a bacterium whose DNA had been removed.

In the latest research, the scientists have created one of the yeast’s 16 chromosomes. Again, they did not build it from scratch but started with the wild chromosome and then made significant changes. They therefore have 15 chromosomes to go, but there is no reason they should not get there.

When Does Autism Begin?

One common feature of unscientific belief systems is that they do not change in the face of new evidence. They tend to evolve like cultural beliefs or marketing campaigns, but do not appear to be affected by scientific evidence in any meaningful way.

One great example of this is the idea the autism is linked to vaccines (to be clear up front, it isn’t) This idea had a few important factors in its origin. The first was simply the existing anti-vaccine movement searching for anything to blame on vaccines. The second, and perhaps decisive, factor was the now discredited and withdrawn study by Andrew Wakefield linking autism to the MMR vaccine.

Even as the MMR claim was dying, the anti-vaccine community was moving onto the next target – mercury (specifically the preservative Thimerosal). This was the target of the book Evidence of Harm by David Kirby. This also created common cause between the anti-vaccine movement, and separate “mercury militia” blaming many modern ills on mercury, and some environmentalists (most prominently Robert Kennedy Jr.) who are keen to blame medical problems on any environmental exposure, including mercury and/or vaccines.

Australian Anti-Vaccination Group Loses Charity Status

The group previously known as the Australian Vaccination Network (AVN) has been getting a lot of heat recently, in large part thanks to the Australian Skeptics who have been exposing their dangerous misinformation. The AVN is an anti-vaccination group that actively campaigns against vaccination. They are (or at least were until recently) also a registered charity, which means they can take tax-deductible donations.

The Australian Skeptics pointed out that the name of the AVN is misleading, as it might make the public think they are giving fair and balanced information about vaccines. In reality the information they dispense amounts to anti-vaccine propaganda.

Recently the New South Wales Department of Fair Trading ruled that the AVN is a misleading name, and ordered the group to change their name. That’s the good new. The bad news is that they decided to change their name to the Australian Vaccination Skeptics Network.

Health of Vaccinated vs Unvaccinated

One of the new realities of social media is that old news can be dredged up and spread around. In this way old memes can keep coming back to life like the Terminator, and we have to kill them over and over again.

The antivaccine crowd, for example, has their narrative of conspiracy and evil and their cherry-picked factoids to support their narrative. In their world vaccines don’t work and are all bad all the time, and only corporate evil and public malfeasance can support them. They scour the internet for anything to support their beliefs, and then splash it around as if it’s news.

In this case, they have resurrected a terrible survey from 1992. The survey was conducted in New Zealand by the Immunization Awareness Society. Unsurprisingly, when this anti-vaccine group surveyed their own anti-vaccine members, they found a higher incidence of disease among vaccinated children compared to unvaccinated children.

Anti-Flu Vaccine Rants at the HuffPo

The Huffington Post continues to be a venue for all sorts of pseudoscience, alternative medicine propaganda, and anti-vaccine sentiments. Two recent posts by Lawrence Solomon in the HuffPo Canada indicate that the nonsense is international.

His first article claims that the majority of health care workers “resist” or “refuse” the flu-vaccine – therefore it can’t be that great. The second attacks the CDC estimates for the number of flu-associated deaths. Together they demonstrate how a bit of motivated reasoning can seem like actual journalism when in fact it leads to misinformation.

Solomon cites statistics about low rates of flu-vaccine update among healthcare workers:

In the UK, only 46 per cent of health care workers — slightly less for doctors (45 per cent) and nurses (41 per cent) — are vaccinated for the flu, despite concerted government efforts according to Public Health England. This startling failure is similar to that seen in Canadian jurisdictions for health care workers today, and those seen in the recent past in the U.S.
