Claims that COVID-19 vaccines “permanently alter your DNA” were resurrected recently based on a dubious study. No matter how many times you think this myth has been debunked, it always comes back for another installment of the same misinformation franchise.
Those opposed to public health interventions to slow the spread of COVID-19, including masks, “lockdowns,” and vaccine mandates, are hyping “natural” immunity again as somehow “superior” to vaccine-acquired immunity. It’s a deceptive simplification of a complex issue.
Marc Girardot is a tech guy turned COVID-19 contrarian. His analogy to falsely “explain” why mRNA vaccines are deadly shows an astounding lack of understanding of basic chemistry.
I have been critical about John Ioannidis over a number of his statements about the COVID-19 pandemic. Now he’s done it again, producing a poor-quality paper whose unwritten assumptions suggest that the Carl Sagan effect, in which scientists are penalized professionally by their peers for becoming popular science communicators, still holds considerable sway in science and medicine.
