“The vaccinated are a danger to the unvaccinated because of shedding!”: The latest COVID-19 antivaccine disinformation
Antivaxxers are masters of projection, which is why the latest antivaccine disinformation about COVID-19 vaccines is that they lead the recipient to "shed" spike protein, which can can cause menstrual irregularities or even miscarriages in women who come into contact with the vaccinated and even make people very sick. This trope is nothing more than a clever repackaging of the old antivaccine...
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.
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.)
