Germ theory denial – another favorite of the anti-vaccine world

I have been meaning to write about germ theory for years because a big part of vaccine denialism requires a good bit of germ theory denialism. Some anti-vaxxers want to create an illusion of scientific integrity by attempting to outright reject the germ theory of disease.

Germ theory is one of the central tenets of biology along with biochemistry, cells, evolution, and genetics. It is not some idea that was invented by those of us who support vaccines just to convince people to get vaccines. It is a foundation of medicine and biology that is centuries old.

This article is going to be a discussion of what exactly is germ theory, and briefly show how the anti-vaxxers deny it to “prove” that vaccines are unnecessary.

YouTube terminated Natural News

YouTube terminated Natural News channel – Mike Adams whines

On 3 March 2018, Google’s YouTube provided us with some good news, because we all need some these days. YouTube terminated Natural News including their whole library of videos. If you search for Natural News on YouTube, you cannot find it. If someone republished one of Natural News videos, it has disappeared. If you have some blog post with an embedded YouTube video with one of Mike Adams’ rants, it will not be there.

In 2017, Google quit indexing Natural News in its searches because of some violation of Google policy by Adams, aka the Health Ranger. We, the science supporters, cheered, as we consider Natural News (and ilk like it) to be at the very bottom of scientific evidence. We all had good fun with it, including the ecstatic Orac, who wrote,

I am, however, very much enjoying my schadenfreude, and will continue to do so as long as Adams’ site is delisted and he continues his tirades against Google and his victimhood conspiracies.

Of course, Adams whined and whined about it with some creative conspiracy theories, although everything we were able to gather about the situation, Natural News violated one of Google’s policies that aim to prevent gaming of search engine optimization. Eventually, Adams corrected the issue, and you could search Natural News again. If that’s your thing.

At least I enjoyed myself for a couple of days. Maybe I can enjoy a year after YouTube terminated Natural News. Maybe a couple of years? Maybe forever?

starving cancer

Starving cancer is not a good way to treat it despite what the internet says

I am a fierce skeptic about cancer. If someone says “starving cancer is better than chemotherapy,” well that means some gullible person will take that advice and forgo more aggressive, and frankly more evidence-based, treatments. And that patient could die.

I’ve written over 200 articles related to cancer on this website. Admittedly, my interest is mainly based on the incredible harm done to people by fake cancer treatments, but others, like editors at Science-Based Medicine and the estimable Orac, are actual experts in cancer, so I’ve just limited myself to sniping from the sidelines, like debunking the nonsense about weed cures cancer. Anyway, I’ll let others do the heavy lifting in cancer articles, I’m just going to focus on the really stupid nonsense that pervades places like Facebook or Quora.

Let me start out with my strategy on cancer claims made on the internet — anyone who oversimplifies prevention, development, or treatment of cancer shall be treated with disdain unless their claims meet the standard of “extraordinary claims demand extraordinary evidence.” If you’re going to tell me that blueberry-kale smothies™ prevent cancer, I want extraordinary evidence in the form of meta-analyses or systematic reviews published in respected biomedical journals. Anecdotes, logical fallacies, and testimonials are NOT DATA.

Furthermore, I need to keep reminding my readers – and various people who push this nonsense – that there are hundreds of different cancers. Each of those cancers has a different etiology, pathophysiology, and treatment strategy. Starving cancer may actually be a brilliant idea – some research is involved in cutting off the blood flow to cancers. But that’s at a very localized level, and changing your diet will have approximately zero effect on cancer development and growth.

On the other hand, I guess you could starve cancer by starving one’s self. But I don’t think there would be a good prognosis and outcome for the patient, especially since eating is problematic when patients are undergoing adjuvant therapy for cancer.

Let’s take a look at the pseudoscience of starving cancer.

pseudoscience medicine

Why does pseudoscience in medicine and vaccines seem so popular today?

These days, it appears that pseudoscience in medicine, everything from homeopathy to anti-vaccine beliefs to cancer treatments to chiropractic to naturopathy, has taken hold of many people’s choices. It’s become so frustrating to read stories about people forsaking science-based medicine to use some quack treatment to treat their cancer.

I think there’s a basic reason for it — science is hard. Whether it results from the lack of education in science to a misunderstanding of science is irrelevant, too many people think that science-based medicine doesn’t work. Except it does.

I’ve written about pseudoscience over a hundred times, but I never answered the question of why it grabs the attention of people. I’m going to try to answer that here.

Pfizer and Moderna mRNA COVID vaccines are really vaccines – obviously

Here we go again – I keep seeing the new anti-vaxxer claim that the mRNA COVID-19 vaccines from Pfizer and Moderna are not, in fact, vaccines but are either “medical devices” or “gene therapy.” I keep trying to stay up with every single myth and trope pushed by the anti-vaxxers, but I swear that there’s a new one every day.

I would really love to write about something other than COVID-19 vaccines – I’ve got a ton of articles I want to write about GMOs, supplements, and cancer that are just sitting in a virtual pile on my desk. Unfortunately, I’m very worried that the anti-vax hatred of these new vaccines will allow this pandemic to keep going. That’s why many of us keep doing the best we can to stamp out the myths.

Just to be clear, the Pfizer and Moderna COVID-19 mRNA vaccines are actually vaccines – they are biological preparations that provide active acquired immunity to an infectious disease, in this case, COVID-19. But, I’m going to have to debunk these myths.

cherry-picking

Cherry-picking – fake science that shows vaccines don’t work and ivermectin does

Since the start of the COVID-19 pandemic, I’ve noticed an epidemic of cherry-picking by people trying to prove this or that about face masks, vaccines, treatments, and mortality. If you don’t spend a lot of time reading the scientific literature on these points, you’d think that there was some sort of scientific debate on everything to do with COVID-19.

Even though some people will try to show that science is all over the place about this pandemic, it really isn’t. We know that facemasks worked, and probably helped reduce the infection rate. And it helped crush the seasonal flu across the world.

We know that the COVID-19 vaccines are very safe and very effective.

We know that all kinds of treatments don’t work from hydroxychloroquine to ivermectin to quack remedies from internet grifters.

And we know that the CDC isn’t intentionally inventing mortality numbers because of…reasons!

So, why does it seem like there are scientific debates about all of these? It’s because we seem to be in a world of false equivalence where cherry-picking one “science” article, irrespective of its merits, can “prove” a contradictory point. But this is not how science is done.

Not to be repetitive, but real science requires one to review all of the published evidence, giving more weight to published studies in respected journals, written by respected scientists, using respected methodologies and analyses, with respected conclusions. It is absolutely not cherry-picking those studies, irrespective of their quality (and they usually have no quality), just to support one’s pre-ordained conclusions. That’s pseudoscience.

I hate cherry-picking unless it’s gathering that delicious fruit. I can get behind that kind of cherry-picking.

Pro-vaccine physicians terrorized by anti-vaxxer hate speech

The LA Times reported recently that pro-vaccine physicians have been 
“terrorized into silence” by hate-filled online harassment from anti-vaccine activists. Since they have almost no scientific evidence supporting their anti-vaccine ignorance, the anti-vaxxers must resort to hate speech to try to shout out the facts about vaccines.

For years, I have watched some of my favorite writers, like Dorit Rubinstein Reiss (who frequently posts content to this blog) and the insolent Orac (yeah, most of us know who Orac is, but it’s hysterical to read articles where the science deniers think Orac is me, Dr. Paul Offit is me, or Dr. David Gorski is me. Oh, wait, Dr. Offit is me again?

But what is not very funny is the unceasing, uncivilized, and ignorant attacks on pro-vaccine physicians. These physicians are promoting vaccines not for fame or fortune, but as a critical public health statement. They don’t deserve this.Read More »Pro-vaccine physicians terrorized by anti-vaxxer hate speech

Anti-vaccine internet trolls try to connect the dots and always get it wrong

This blog, and by extension this writer, has been skewered by anti-vaccine trolls so many times, it has become a badge of honor. I mean, I don’t really take myself too seriously, the whole point of this blog is mock pseudoscience.

Let’s see. I’ve been accused of being a shill of Big Pharma (about a thousand times), Kaiser Permanente, and Monsanto (another thousand times). These anti-vaccine trolls certainly believe I must be rolling in the gold bullion from these companies.

I’ve been called a sock puppet of Dorit Rubinstein Reiss (who’s a nice person, a description that could be used for me only if you’re stoned). I’ve been called an astroturfer by the antivaccine “journalist,” Sharyl Attkisson.

One more silly accusation and I believe I get the skeptic merit badge for Laughing at Ad Hominem attacks. I’ve been working hard on it thanks to the anti-vaccine trolls.

But most of the junk science that comes my way is fairly easy to mock. It writes itself, as they say. Frankly, there’s just too much out there on the internet. I bet most skeptics ignore 99% of the silliness on the internet. I mean Natural News would require 24/7 debunking.

So that brings me to something that showed up on my email this morning. It’s a blog post, by a blogger named Marco Cáceres di Iorio, entitled “Internet Trolls Attack Anyone Resisting Vaccine Party Line.” Read away if you want, it’ll probably be the most hits his blog will get ever.

Usually, I ignore this stuff. But hey, he called me “troll.” Oh no. Except, this new member of the anti-vaccine trolls connected the dots in such a way that I’m not sure if I should feel honored. Or insulted. Possibly both? What

Measles prevents cancer? Another anti-vaccine myth with no evidence

Darla Shine, a former Fox News producer, and wife of the White House deputy chief of staff of communications, of course, posted a dangerous and ignorant tweet that implied that measles prevents cancer.

Shinee is repeating a thoroughly debunked anti-vaccine religious trope, but what do you expect from a Trump sycophant? The truth? Especially since Trump has a history of anti-vaccine rhetoric.

Of course, there is a reason why this myth has legs, but it’s not based on what we call robust evidence – it’s based on pseudoscience, misinformation, and nonsense.Read More »Measles prevents cancer? Another anti-vaccine myth with no evidence
