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.

Prions and Creutzfeldt‐Jakob disease

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...

Pfizer/BioNTech COVID-19 vaccine

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.

Pfizer/BioNTech COVID-19 vaccine

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,...

It was inevitable that antivaxxers would claim that COVID-19 vaccines make females infertile

Antivaxxers have been claiming that vaccines cause female infertility for as long as I can remember. So it's not surprising that they are now claiming that COVID-19 vaccines will cause miscarriages or even make women infertile. Their assertion is based on a highly speculative and incredibly unlikely immunologic mechanism. Same as it ever was.

No, the Moderna and Pfizer RNA vaccines for COVID-19 will not “permanently alter your DNA”

With the new mRNA vaccines developed by Pfizer/BioNTech and Moderna likely to be available soon, antivaxxers have been ramping up the fear mongering. Their latest claim is that mRNA vaccines will "permanently alter your DNA" or even "make you transhuman." Such claims rest on an utter ignorance of the totality of what we know about the biology of DNA, RNA, and how...
