Frameshift mutation

Do mRNA vaccines produce harmful “junk proteins” that “gunk up” the cell and cause unintended “off-target” immune responses?

A new study is making the rounds in the antivax crankosphere. The study found that the modified mRNA used in the Pfizer vaccine can cause a frame shift (to be explained) that results in the production of proteins besides the intended spike protein. The findings are, as you probably guessed, a big nothingburger compared to how they are being spun.

The Pfizer COVID-19 vaccine doesn’t prevent transmission: Antivax disinformation goes viral again

Last week, antivaxxers were all over social media after Tucker Carlson touted a "revelation" that the phase 3 clinical trial used to support licensure of the Pfizer COVID-19 vaccine didn't examine its ability to block transmission as meaning that its inability to block transmission had been "covered up". It wasn't, and antivaxxers are ignoring everything we've learned over the last two years...

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...

The return of the revenge of “COVID-19 mRNA vaccines permanently alter your DNA” and “lab leak”

Claims that COVID-19 vaccines "permanently alter your DNA" or that SARS-CoV-2 was engineered in a lab were resurrected last week based on two dubious studies. No matter how many times you think these myths have been debunked, they always come back for another installment of the same misinformation franchise.

To unblind or not to unblind? That is the question about clinical trials of COVID-19 vaccines

Antivaccine alternative health tycoon Joe Mercola claims that the unblinding of participants in the clinical trials of Moderna and Pfizer COVID-19 vaccines was intended to "blow up the trials" and undermine the science, making it impossible ever to identify long term adverse events. What he's really doing is deceptively oversimplifying complex ethical and scientific issues surrounding these trials in the middle of...

COVID-19 vaccines versus “purity of essence”

Antivaxxers frequently make the false claim that mRNA-based COVID-19 vaccines "permanently alter your DNA". These claims are really a concern about "impurifying" their "purity of essence".

Antivaxxers, COVID-19 vaccines, and “hacking the software of life”

Antivaxxers and COVID-19 conspiracy theorists were always going to spin conspiracies about COVID-19 vaccines. Unfortunately, some scientists have made it so much easier for them by having likened mRNA vaccines to "hacking the software of life" and being unclear on what gene therapy is.

COVID Vaccines Probably Prevent Spread

The evidence is preliminary, but it looks like the COVID vaccines do reduce the risk of spread of SARS-CoV-2.

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.

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...
