Another non-peer-reviewed preprint article about natural immunity versus vaccines for COVID-19 is being used as the “gotcha” moment for the anti-vaxxers. And on the surface, the article might be interesting, but it’s being misused. What a shocker.
I’m going to do a quick review of the article, then remind everyone why vaccinations are ALWAYS better than natural immunity. Outcomes from diseases that are prevented by the vaccine must be weighed against the safety and effectiveness of that vaccine. This is a necessary risk-benefit analysis that is required by every procedure or pharmaceutical in evidence-based medicine. And, this is the point that is missed by those pushing this new preprint.

It’s that time of year when we are bombarded by flu treatment quackery from “immune-boosting” miracle supplements to junk that “cures” every single virus known to medical science. During this world of the coronavirus pandemic, it seems to be even louder.
This article will attempt to debunk the myths of flu treatments such as “boosting the immune system,” magical supplements, and other nonsense involved with the world of flu treatment pseudoscience.
The one way to prevent the flu, other than hiding in a bubble during the winter (which may be a good thing with the COVID-19 pandemic), is the seasonal flu vaccine. But that’s not a treatment, it prevents the flu.

And here we go again. The interwebs are filled with quacks trying to claim that they have something for boosting immunity to protect oneself from COVID-19. Of course, once you read that someone has the magical potion for boosting immunity, you can almost guarantee that it’s pseudoscience and woo.
Boosting immunity is always the go-to for scam artists whenever there is a deadly outbreak or pandemic like we are seeing now. The pseudoscience of the immune system is pernicious and possibly dangerous.
The problem with these immune system myths is that they overlook or ignore a basic physiological fact – the immune system is a complex interconnected network of organs, cells, and molecules that prevent the invasion of hundreds of thousands, if not millions of pathogens and other antigens every single day.
And no matter how much individuals try to trivialize the complexity of the immune system, it does not make it so. If it were easy as downing a handful of supplements or the magical blueberry-kale smoothie for boosting immunity to coronavirus or any disease, every physician in the world would prescribe.
Unfortunately, even if we could boost our immunity, we shouldn’t – a hyperactive immune system is frequently dangerous to an individual.
Yeah, the pseudoscience crowd doesn’t know their immune system.

The old Skeptical Raptor took a bit of a break to recharge their batteries to tackle all of the pseudoscience that will be coming out in 2020. In lieu of new content, I will be republishing the top 10 most read articles on this blog during 2019. Here’s number 1 – the queen of the false authority of the anti-vaxxers – Tetyana Obukhanych.
One of their favorite pseudoscientists of the anti-vaccine religion is Tetyana Obukhanych, someone who appears to have great credentials. Unfortunately, once you dig below the surface of her claims, there is no credible evidence in support.
One of the most irritating problems I have with the anti-vaccine movement is their over-reliance on false authorities – they overrate publications (often in worthless predatory journals) or commentary from someone who appears to have all of the credentials to be a part of the discussion on vaccines, but really isn’t close to being a real vaccine scientist.
Nevertheless, credentials don’t matter – an “authority” on vaccines must follow the evidence that vaccines are safe and effective unless those “authorities” can provide robust, peer-reviewed, published evidence that vaccines aren’t. Someone like Tetyana Obukhanych almost never does.
For example, Christopher Shaw and Lucija Tomljenovic, two researchers in the Department of Ophthalmology at the University of British Columbia, have, for all intents and purposes, sterling credentials in medicine and science. However, they publish nonsense research (usually filled with the weakest of epidemiology trying to show a population-level correlation between vaccines and adverse events) in low ranked scientific journals.
Following in the footsteps of Shaw, Tomljenovic, James Lyons-Weiler, and Christopher Exley, let’s take a look at the background and education of the anti-vaccine hero, Tetyana Obukhanych. Continue reading “Tetyana Obukhanych – another anti-vaccine appeal to false authority”
Recently, I wrote an article about measles immune suppression, a serious complication of the disease, and one of the great reasons to get the measles vaccine. According to two peer-reviewed articles, one published in the prestigious journal Science and the other article in a sister journal Science Immunology, researchers described that measles infections destroyed some immune memory cells, causing the individual to lose protection to some diseases.
Of course, the anti-vaccine zealots’ favorite false authority, Tetyana Obukhanych, decided to deny the solid scientific articles that established one of the well-known complications of measles. It’s not like anyone should take her babbling pseudoscience seriously, but just in case someone does, it’s important that we point out that Obukhanych is wrong once again.

It’s been well known for years that measles damages the immune system, one of the many dangerous complications of the disease. That’s one of the many reasons why we are so strongly in favor of the MMR vaccine and so strongly against measles outbreaks.
Of course, the anti-vaccine zealots will continue to believe that “natural” measles infections will confer some super-immunity to their children. Many deliberately try to infect their kids with the disease.
However, this scientific research, published in one of the most prestigious peer-reviewed scientific journals on this planet, provides convincing evidence that measles damages the immune system. And we should make sure our children don’t contract this dangerous disease. Continue reading “Measles damages the immune system – more reasons for MMR vaccine”
I wrote this article over five years, debunking the claim that bananas prevent cancer, and it remains the most popular article I’ve ever written. It probably gets so much traffic because of the ongoing memes about how bananas will cure every cancer known to man.
Too many individuals see these memes on Twitter and Facebook, then they accept them as scientific facts. They rarely are. That’s why critical thinking is necessary.
But if a meme is going to make an extraordinary claim, like bananas prevent cancer, then that claim ought to be backed by extraordinary evidence. But this wild belief about bananas is not even supported by ordinary evidence. It is supported by zero evidence.

One of the pervasive myths expressed by the anti-vaccine world is that one or all childhood vaccines can be replaced by breastfeeding. Somehow, these people believe that breast milk is such a powerful agent of the immune system that vaccinations are unnecessary. But that’s not based on any science related to human physiology, especially with respect to the immune system.
These beliefs represent a misunderstanding of how our immune system functions, especially regarding the role of passive immunity. Breastfeeding, of course, has a lot of benefits to both the developing baby and the mother. But we shouldn’t endow it with magical qualities, especially with regards to how it operates with the infant’s own immune system.
I want to take some of your time here to give a condensed version of immunology, especially the differences between passive and adaptive immunity. And I want to show how breastfeeding complements the developing baby’s immune system. Continue reading “Breastfeeding cannot replace a vaccine – let’s talk about passive immunity”
One thing you’ll notice from all science deniers is a tendency to overstate or overuse a fairly solid scientific principle inappropriately. The anti-vaccine crowd takes this to a whole new level. And what we’re going to discuss today is the hygiene hypothesis, which describes how early exposure to microorganisms may assist the immune system to avoid allergic reactions.
Although we’ll discuss the scientific evidence in support of the hypothesis later in this article, anti-vaxxers tend to abuse it. They conflate potentially beneficial organisms, such as the gut biome, with dangerous and deadly pathogens, like measles and polio. The former may be a critical component of the hygiene hypothesis, but the latter is not.
Time to tackle this scientifically controversial topic, and put to rest one of the tropes of the anti-vaccine religion that all germs are good. Continue reading “Hygiene hypothesis – what is it, and why the anti-vaccine religion abuses it”
Immune system myths are one of the common claims of the junk medicine crowd, especially the anti-vaccine activists. The pseudoscience of the immune system is pernicious and possibly dangerous.
It’s frustrating that the pseudoscience from the junk medicine crowd claims that this supplement or that food is critical to boosting the immune system – hang out for a day on Facebook, and you’ll probably see way too many memes saying that all you have to do to boost your immune system is eat a blueberry kale smoothie. I still see that dumb banana claim that it cures cancer.
The problem with these immune system myths is that they overlook or ignore a basic physiological fact – the immune system is a complex interconnected network of organs, cells, and molecules that prevent invasion of the body by hundreds of thousands, if not millions of pathogens and other antigens every single day.
And no matter how much individuals try to trivialize the complexity of the immune system, it does not make it so. One can claim all day long that downing a few tablets of echinacea will boost the immune system to prevent colds (it doesn’t), it doesn’t make it scientifically accurate. Nor does it create an accurate description of the immune system.
