Can mRNA-based COVID-19 vaccines cause prion disease or Alzheimer’s?
Antivax immunologist J. Bart Classen published a paper claiming that mRNA-based COVID-19 vaccines can cause prion disease leading to neurodegenerative diseases like Alzheimer's dementia. What are prions, and can these vaccines cause prion disease? (Spoiler alert: The answer to the second question is almost certainly no. It's speculation based on highly implausible biology.)
Lipid nanoparticles in COVID-19 vaccines: The new mercury to antivaxxers
When it comes to antivaccine misinformation and the COVID-19 pandemic, everything old is new again, at least if you haven't been paying attention. This time around, it's the resurrection of an old favorite antivaccine trope, the "toxins" gambit. Truly, lipid nanoparticles are the new mercury.
The latest antivax false claim: mRNA vaccines against COVID-19 are not vaccines but “medical devices” or “gene therapy”
There's a new antivaccine talking point in town, and it's just as much disinformation as other antivaccine talking points. It's the claim that mRNA COVID-19 vaccines are not really vaccines but "medical devices," "gene therapy," or "experimental biologics" and that they were falsely classified as vaccines in order to bypass safety testing. Here, we discuss why this claim is utter nonsense based...
The efforts of antivaxxers to portray COVID-19 vaccines as harmful or even deadly continue apace (VAERS edition)
With the rollout of COVID-19 vaccines continuing apace, so are the efforts of antivaxxers to portray the vaccines as dangerous. This time around, they've resurrected the old antivaccine trick of deceptively misusing the VAERS database to imply causation from VAERS reports. That's not how VAERS works, however.
All science denial is a form of conspiracy theory
Regular readers of this blog know that many forms of quackery and science denial have conspiracy theories associated with them, but a further examination suggests that all forms of science denial are a form of conspiracy theory. In the middle of a deadly pandemic, science denial represents a form of conspiracy theory with potentially deadly consequences.
The efforts of antivaxxers to portray COVID-19 vaccines as harmful or even deadly continue apace…
As more and more COVID-19 vaccines find their way into more and more arms, there are reports of bad things happening to people after vaccination up to and including even death. As I've been predicting for a long time that they would, antivaxxers are now weaponizing these reports and anecdotes before they have even been investigated in order to spread fear, uncertainty,...
Did the Pfizer/BioNTech COVID-19 vaccine cause a fatal case of ITP?
Last week, a post by Heidi Neckelmann, the wife of Miami obstetrician Dr. Gregory Michael describing his death from idiopathic thrombocytopenic purpura (ITP) 16 days after being vaccinated with the Pfizer/BioNTech COVID-19 vaccine went viral. Unsurprisingly, in her grief she blamed the vaccine for her husband's death from a rare autoimmune condition that destroys platelets and causes bleeding. Unfortunately, Dr. Michael's tragic...
2020 and the pandemic: A year of (some) physicians behaving badly
Looking back on 2020, if there's one thing that the COVID-19 pandemic has taught us, it's that crises reveal character. Unfortunately, the character of too many physicians has been found wanting, as they spent 2020 denying the pandemic, peddling quack cures, or spreading misinformation in the service of defying public health interventions. What can be done?
Syncope and Bell’s palsy: Distinguishing correlation from causation for adverse events observed after COVID-19 vaccination
The FDA has approved emergency use authorizations (EUAs) for two COVID-19 vaccines, and the largest mass vaccination program in history has begun. Look for antivaxxers to attribute reactions to the vaccine that the vaccine very likely didn't cause. We'll examine the example stories of vasovagal syncope and Bell's palsy that were reported by the press last week.
Deciding between a vaccine and…an infection?
A handy comparison of COVID-19 vaccines compared to COVID-19 infections.
