From that article - But Carlson was citing a letter in which the authors’ evidence was a dubious blog that lists news reports of people all over the world, of all ages, dying or experiencing medical emergencies. The blog proves no relationship between the incidents and COVID-19 vaccines; it also includes in its count reported deaths from cancer and emergencies of unknown causes.

“It’s not real research, but he quotes it as if it’s real research,” said Dr. Matthew Martinez, director of sports cardiology at Atlantic Health System in Morristown Medical Center. “Anybody can write a letter to the editor and then quote an article that has no academic rigor.”

Notice how they dismiss the "dubious blog" without even offering a name or link so people can check for themselves? Nope, just take our word for it -> "dubious blog"😱😱smh
