“Natural immunity” versus the vaccine for COVID-19
Antivaxxers have long appealed to "natural immunity" as being somehow inherently superior to vaccine-induced immunity, which is apparently "artificial". This is a trope that comes from alternative medicine concepts about purity and contamination that is now endangering us in the age of the pandemic.
State medical boards vs. COVID-19 misinformation, an update
The disinformation epidemic about COVID-19 has pushed state medical boards to consider disciplining physicians who promote COVID-19 disinformation. How would that work? What are the obstacles? Is it even possible? It should be, but it will be messy and complicated.
The dumpster diving VAERS preprint debacle: How did we get here?
Last week, SBM devoted a lot of digital ink to a poorly done study analyzing the VAERS database for myocarditis after COVID-19 vaccination that was widely publicized to imply that the vaccine is more dangerous than the disease. Three out of the four authors should have known better, leading me to ask: How did we get here?
Dumpster diving in the VAERS database to find more COVID-19 vaccine-associated myocarditis in children
"Dumpster diving" is a term used to describe studies using data from the Vaccine Adverse Events Reporting System database by authors, almost always antivaxxers, who don't understand its limitations. Last week, non-antivax doctors who should know better fell into this trap when they promoted their study suggesting that COVID-19 mRNA vaccines are more dangerous to children than the disease.
Yes, the FDA really HAS given full approval to the Pfizer/BioNTech COVID-19 vaccine
After the FDA announcement a week ago that Comirnaty, the COVID-19 mRNA vaccine developed by BioNTech and Pfizer, had been approved, it took less than a day for antivaxxers to spin a conspiracy theory claiming that the FDA hadn't really approved the Pfizer vaccine at all and that Comirnaty wasn't available, all to protect Pfizer from liability. It's a superficially plausible conspiracy...
The Federation of State Medical Boards vs. COVID-19 misinformation: A losing battle so far
A few weeks ago, the Federation of State Medical Boards, which itself does not have any regulatory power but advocates for state medical boards, issued a statement that physicians who spread COVID-19 misinformation should be subject to disciplinary measures. Unfortunately, a recent report found that not a single US physician has had action taken against their medical license for doing this. Why?
Are vaccines driving the emergence of “escape mutant” variants of COVID-19?
Geert Vanden Bossche is back, and this time he's blaming COVID-19 vaccines for driving the evolution of more dangerous "escape variants" of SARS-CoV-2, the coronavirus that causes the disease, that are capable of evading vaccine-induced immunity. As antivaxxers making this argument always do, unfortunately, he ignores the much larger problem in which free circulation of the virus is a far more powerful...
Joe Mercola: An antivaccine quack tycoon pivots effortlessly to profit from spreading COVID-19 misinformation
Joe Mercola is a physician whose nearly quarter-century of promoting quackery and antivaccine misinformation has garnered him a net worth north of $100 million. It is therefore not surprising that in the age of the pandemic, he has pivoted to fatten his bottom line promoting misinformation and conspiracy theories about COVID-19 and the COVID vaccines.
We are not “losing the war on cancer” (belated 2021 edition)
The narrative we hear time and time again is that we are "losing the war on cancer". The latest cancer statistics show that this narrative is not true.
