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 “12% efficacy” myth from the “Pfizer data dump”: The latest slasher stat about COVID-19 vaccines

Last week, a claim that Pfizer's own documents demonstrate that the efficacy of its COVID-19 vaccine was only 12% (not the 95% reported) went viral. This is a slasher stat, so-named because it is not new and, like the killers in slasher movie series, even when it appears to be dead it always appears in another installment of the misinformation franchise to...

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.

What the heck happened to The BMJ?

Last week, The BMJ published an "exposé" by Paul Thacker alleging patient unblinding, data falsification, and other wrongdoing by a company running three sites for the massive clinical trial of the Pfizer COVID-19 vaccine. It was a highly biased story embraced by antivaxxers, with a deceptively framed narrative and claims not placed into proper context, leading me to look into the broader...

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...

“COVID-19 vaccines are going to sterilize our womenfolk,” Take 2

Antivaxxers have long claimed that vaccines, particularly HPV vaccines, can damage the ovaries and cause female infertility. That claim has been resurrected for COVID-19 vaccines. The first example relied on a dubious "similarity" between the SARS-CoV-2 spike protein and a placental protein. This time, it's the lipid nanoparticles attacking the ovaries, echoing very old claims about polysorbate-80. Truly, everything old is new...

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...
