There are so many anti-vaccine religious tropes about the safety of vaccines, that it is often hard to keep them all straight. One of the current ones is that vaccines cause autoimmune diseases such as multiple sclerosis. Does scientific evidence support the hypothesis that vaccines cause multiple sclerosis?
Well, I have written about whether vaccines cause multiple sclerosis before, and based on the scientific evidence (see here and here), there simply was no link between them. Of course, with the anti-vaccine religion, evidence be damned, they will stand by their claims. All I can do is repeat myself with more and more evidence, refuting their claims.
There is a new review of the evidence of whether vaccines cause multiple sclerosis, and once again, they found nothing. And once again, I will review the evidence to see if there is something to the claims of the anti-vaccine religion. I should give a spoiler alert, but you all know what’s coming.

The upcoming flu season may be a rough one. A strain of the influenza A, H3N2, is showing up in small clusters of outbreaks throughout the USA. Unfortunately, the 2017 flu vaccine effectiveness against the H3N2 may be lower than expected.
We will get into the details further in this post, but I do not want to bury the headline. This does not mean the 2017-18 flu vaccine is ineffective – the quadrivalent 2017 flu vaccine effectiveness against three of four flu strains is still fairly high. The flu vaccine is extremely important in stop lots of flu strains, and just because it may have an issue with one of the four strains, does not imply that it is useless.
Let me repeat that, just in case someone misses the point – only one of the four strains of flu in the 2017-18 vaccine may have lower effectiveness. The vaccine remains highly effective against the other four strains. Continue reading “2017 flu vaccine effectiveness – getting the facts straight”
One of the central tenets of science is whether correlation implies causation. The anti-vaccine religion often conflates or misunderstand the two, rejecting or accepting causation as it fits its narrative. The “correlation implies causation” story is often abused, misused and confused by many writers.
We, the pro-science/pro-vaccine world, dismiss correlation implies causation, unless a checklist of of supporting information can be checked off.
Conflating causation and correlation is somewhat different than the logical fallacy of post hoc ergo propter hoc, where one thinks one event follows the first event because of the existence of the first event. I’m sure all good luck charms and superstitions, like walking under a ladder, are related to the post hoc fallacy. So if I walk under a ladder, then trip on a black cat, then crash into a mirror, I don’t immediately blame the initial act of walking under the ladder. I just assume I’m clumsy.
In science, we may be able to show correlation statistically. For example, there may be an increase in broken bones in children after vaccination. But does that mean the vaccine caused the broken bone? If we show that the rate of broken bones is the same with or without vaccines, there’s no causation. If we cannot show a plausible physiological reason why vaccines would have some influence over bone strength, we reject causation. In other words, showing correlation gives us only half the story. Real science is necessary to show us causality.
Correlation and causation are a very critical part of scientific research. Basically, correlation is the statistical relationship between two random sets of data. The closer the relationship, the higher the correlation. However, without further data, correlation may not imply causation, that the one set of data has some influence over the other.

About 4 years ago, I wrote about a new anti-Gardasil name being foisted upon the internet. His name is Bernard Dalbergue, a French physician who may or may not have had some role with Gardasil development. Or manufacturing. Or sales.
Well, he had something to do with something with regards the HPV cancer-preventing vaccine. He’s another false authority pushed by the anti-Gardasil religion, a particularly nasty sect of the anti-vaccine religion. They bring out these individuals because the anti-vaccine troupe lacks the evidence to support their specious and deceptive claims about Gardasil.
So let’s dig in to this Bernard Dalbergue. Let’s see if there’s anything there. Continue reading “Bernard Dalbergue and Gardasil – another anti-vaccine shill says nothing”
You’ve got to hand it to the anti-vaccine pseudoscience activists – they are nothing if not dedicated to their religious beliefs. And like the so-called “creation science” religion, which tries to “prove” their evolution denialist beliefs with pseudoscience published in creationist journals, the anti-vaccine religion tries to “prove” that vaccines are dangerous with bad science, pseudoscience, and misinterpreted science.
As of today, I’ve written a dozen or so articles about Christopher Shaw and Lucija Tomljenovic, contemptible University of British Columbia anti-vaccine pseudoscience extremists. Shaw and Tomljenovic are well known for pushing garbage science to further their anti-vaccine religion. Of course, their “scientific articles” keep getting retracted, despite being published in low ranked journals whose standards rarely exceed “please use a good spell checker.”
Now, we have a new article trying to push the myth that somehow the tiny amounts of aluminum in vaccines are related to autism. Of course, we have hundreds of real scientific articles published in real scientific journals which have demolished the myth that vaccines cause autism. But these persistent anti-vaccine pseudoscience pushers keep trying. Because one of the central tenets of pseudoscience is to have a pre-ordained conclusion, and find any evidence, irrespective of quality, to support it.
So we’re going to take a look at this new “article.” I always examine anti-vaccine “research” from two perspectives – first, I take a look at the author(s), the journal, and other factors that might have an impact on our critique of the study. Second, I then critique the scientific data, methods, and conclusions. So, here we go, into the fray. Continue reading “Anti-vaccine pseudoscience – more bad science on autism and aluminum”
According to recent studies from the CDC, only about 63% of teen girls and 50% of teen boys have started the HPV vaccination series. The relatively low vaccine uptake, despite the evidence that Gardasil prevents cancer, one of the few ways to actually prevent cancer, is especially frustrating to those of us who are supporters of the vaccine. However, new data that Gardasil prevents cancer may drive acceptance for the vaccine – new research appears to show that the HPV vaccine may protect against head and neck cancers.
Gardasil 9, the most current version of the vaccine, was approved to protect against cervical, vulvar, vaginal, and anal cancers in females along with anal cancers in males – if it is also shown to prevent oropharyngeal cancers (and eventually gets new indications after FDA review), maybe that can increase the lagging HPV vaccination rates.

There was an article published in Pediatrics that described how educating either teenagers or their parents about HPV vaccinations had little effect on the overall vaccination rate for the vaccine. Essentially, the researchers found that it was a 50:50 probability that any teen would get the vaccine, regardless of their knowledge of HPV and the vaccine itself. Some of the reasons why the HPV vaccine uptake is so low is a result of several myths about Gardasil safety and efficacy.
So I thought about why that Pediatrics study found that education about HPV and Gardasil didn’t move the needle on vaccination uptake. It’s possible that the benefits of the vaccine is overwhelmed by two factors–first, that there’s a disconnect between personal activities today vs. a disease that may or may not show up 20-30 years from now; and second, that the invented concerns about the HPV quadrivalent vaccine, promulgated by the usual suspects in the antivaccination world, makes people think that there is a clear risk from the vaccine which is not balanced by preventing cancer decades from now. It’s frustrating. Continue reading “Gardasil safety and efficacy – debunking the HPV vaccine myths”
The many myths about the HPV cancer preventing vaccine, known as Gardasil, have been critical in keeping uptake of the vaccine low. For example, many parents believe that their children will never engage in risky sexual behavior, so why do they need to give them the HPV vaccine? Of course, this ignores the facts that sexual assault and the sexual history of future partners can lead to HPV infection.
A newly published article also may show that male virgins (and presumably female virgins) can contract an HPV infection. HPV is so infectious that it can be transmitted even without sexual intercourse.
Let’s examine this new study which is more conclusive evidence that parents should seriously consider getting the vaccine for their children. Continue reading “HPV infection of male virgins – reason for cancer preventing vaccine”
The enormous economic value of vaccination – that is, the economic benefits of a vaccine far outweighs the costs – is often overlooked, especially by those who invent some massive conspiracy by “Big Pharma” to push vaccines.
The standard anti-vaccine trope is that vaccines are a gargantuan profit center for pharmaceutical companies. That would be false. In fact, if we are going to endow Big Pharma with immorality and evil motives, they would stop making vaccines and profiting off of the massive illnesses that would ensue. But that’s not what happens.
The facts are that pharmaceutical companies manufacture and market vaccines at a moderate profit, forsaking the much larger profits in a world with rampant vaccine-preventable diseases. I’m not one of those naïve individuals who think that Big Pharma is filled with 100% altruistic and moral individuals. However, it mostly is.
Moving away from the economic benefits and profits for the pharmaceutical industry, there is a tremendous economic value of vaccination for society at large. And it’s important to make this clear to anyone who is willing to listen.

Dorit Rubinstein Reiss – Professor of Law at the University of California Hastings College of the Law (San Francisco, CA) – is a frequent contributor to this and many other blogs, providing in-depth, and intellectually stimulating, articles about vaccines (generally, but sometimes moving to other areas of medicine), social policy and the law. Her articles usually unwind the complexities of legal issues with vaccinations and legal policies, such as mandatory vaccination and exemptions, with facts and citations. I know a lot of writers out there will link to one of her articles here as a sort of primary source to tear down a bogus antivaccine message.
Professor Reiss writes extensively in law journals about the social and legal policies of vaccination–she really is a well-published expert in this area of vaccine policy, and doesn’t stand on the pulpit with a veneer of Argument from Authority, but is actually an authority. Additionally, Reiss is also member of the Parent Advisory Board of Voices for Vaccines, a parent-led organization that supports and advocates for on-time vaccination and the reduction of vaccine-preventable disease.
Below is a list of articles that Dorit Rubinstein Reiss has written for this blog, organized into some arbitrary and somewhat broad categories for easy reference. This article will be updated as new articles from Professor Reiss are added here.
