Shedding vaccine COVID-19

Antivax quacks are continuing to make up fantastical biological mechanisms for COVID-19 vaccine “shedding”

A couple of weeks ago, I discussed why antivax quacks' claimed biological mechanisms for COVID-19 vaccine "shedding" reminded me of homeopaths. Confabulation about fantastical scientific mechanisms continues, courtesy of "A Midwestern Doctor."

“New school” antivax goes old school as Byram Bridle asks if COVID-19 vaccines will drive an “epidemic” of autism

Wakefield redux? Antivax scientist Byram Bridle just took the "new school" antivax movement old school by implying that COVID-19 vaccines might cause an "epidemic of autism." Everything old is new again, sort of.

Shedding is not a thing for SARS-CoV-2 mRNA vaccines.

Why antivax arguments for COVID-19 vaccine “shedding” remind me of homeopathy

An antivaxxer by the 'nym "A Midwestern Doctor" makes an argument that COVID-19 vaccine "shedding" is not impossible despite the basic science that concludes it is. Sound familiar?

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.

Turbo cancer?

Dr. William Makis and “turbo cancer”: Falsely blaming COVID-19 vaccines for cancer

A prominent oncologist and cancer biologist, Wafik El-Deiry, recently amplified claims that COVID-19 vaccines cause "turbo cancer," wanting a "civil discourse about science and actual answers that are missing." Unfortunately, calls for "civil discourse" by an eminent oncologist about unfounded claims only lends undeserved credibility to them. So, once more into the fray...

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.

“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...

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.
