Antivaxxers misrepresent a study to falsely claim that COVID-19 vaccines cause cancer

The latest antivaccine propaganda claims that a 2018 research paper published by researchers at Memorial Sloan-Kettering Cancer Center shows that the RNA in the Moderna and Pfizer COVID-19 vaccines can cause cancer. As usual, it's a complete misapplication of a cherry picked study grounded in a lack of understanding of molecular biology. Same as it ever was.

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.)

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.

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,...
