COVID-19 vaccination and myocarditis: another preprint


A preprint from Thailand gives us more information about vaccine-associated myocarditis in younger people, but should not be weaponized by antivaccine activists as a reason to avoid vaccination against COVID-19.

Conspiracy theories about monkeypox: Déjà vu all over again or same as it ever was?


Last Thursday, the Biden administration officially declared monkeypox to be a national public health emergency. Unsurprisingly, conspiracy theories abound, many of them recycled from COVID-19 and older antivax conspiracy theories.

Announcing a New Children’s Book that Promotes Critical Thinking


A new book teaches young children about critical thinking and evidence. It's not only educational but colorful and funny. Too many adults are like Henry, the little boy in the story who rejects clear evidence and persists in what he wants to believe.

The rise and fall of the lab leak hypothesis for the origin of SARS-CoV-2


Two new studies were published last week that strongly support a natural zoonotic origin for COVID-19 centered at the wet market in Wuhan, China. Naturally, lab leak proponents soberly considered this new evidence and thought about changing their minds. Just kidding! They doubled down on the conspiracy mongering, because of course they did.

Debating How to Debate Instead of Actually Debating


Every moment spent debating who can say what to whom and how and where they should say it, is time not spent talking about doctors who repeatedly underestimated the virus and successfully campaigned to ensure tens of millions of children and young adults contracted it before they were vaccinated.

“Natural Immunity” Stans Forget Babies Will Always be Vulnerable to COVID


Children are still getting hospitalized with COVID, no matter how many times contrarian doctors mindlessly repeat the mantra "natural immunity". Doctors who know where babies come from understand why this might be.

A Desperate Choice


In a recent article in the New England Journal of Medicine I read about a novel possibility for treating cancer that I had not been aware of. The study’s title was “Oncolytic DNX-2401 Virus for Pediatric Diffuse Intrinsic Pontine Glioma.” It started by saying that pediatric patients with diffuse intrinsic pontine glioma (DIPG) have a poor prognosis, with a median survival […]

Novavax: It’s the vaccine that scares antivaxxers, not moth DNA or any ingredient in any vaccine


The Novavax COVID-19 vaccine was recently granted emergency use approval by the FDA. Company executives and some public health officials have expressed hope that this recombinant protein-based vaccine will be more palatable to the vaccine-hesitant than existing vaccines using new (and therefore scarier) mRNA and adenovirus platforms. The reaction to the use of moth cells to produce the Novavax vaccine shows that It's the vaccine, not any platform or ingredient.

Minimizing COVID Via Postmodernism


An exploration of how, under the guise of "reason", doctors, desperate to be different no matter the evidence, have embraced the position that there are no aspects of reality that are objective and that feelings matter more than facts.

Science-Based Satire: A Powerful and Ancient Practice is Revolutionizing Medical Venipuncture


Are experts in medical dowsing using medical grade rods to locate blood vessels to improve venipuncture success rates? No, they aren't. That's absurd and this is clearly satire. But dowsing for dead bodies might be accepted in a court of law near you, which is also absurd but not made up. Really.

Chiropractic Neck Manipulations in the News


Caitlin Jensen's chiropractor called 911 when she developed alarming symptoms after neck manipulation. She had a heart attack, was pulseless for 10 minutes, and suffered traumatic brain injury. Surgeons found dissections of 4 arteries in the neck. A month later, she remains paralyzed and is still in the ICU.

COVID-19 puts the spotlight on an unexpected racial disparity in health care


Evidence is increasingly suggests that pulse oximeters, the little finger clips that measure blood oxygen, overestimate the blood oxygenation in Black patients. It's a problem that's been discussed a long time that took a pandemic to bring to public consciousness. How can SBM decrease or eliminate such healthcare disparities?

In What Is a Woman?, Matt Walsh asks a question, but doesn’t like the answers


Matt Walsh's documentary asks What Is a Woman? Unfortunately, his documentary is every bit as much of a science denying propaganda film disguised as a documentary as antivax films like VAXXED or the anti-evolution film Expelled!, and such films tend to be potent messaging tools.

100% Cure Rate Is Hard to Believe


An experimental cancer drug made 100% of rectal cancers disappear in a small trial, allowing subjects to avoid the standard treatment of chemotherapy and surgery . “Some scientists say these kinds of results have never been seen in the history of cancer research.” 100% is hard to believe; the 95% confidence interval was 74 to 100. Whatever the true percentage, if this […]

Is COVID-19 “the forever plague”?


A recent article claims that Omicron reinfections confer "no immunity" such tha it's possible to be reinfected with Omicron variants every two to three weeks and calls COVID-19 the "forever plague." Although it makes a reasonable point that "natural" postinfection immunity doesn't last long because of variants, the article is undermines its reasonable criticisms of COVID policy with maximal fear mongering.
