What separates the two? A lot, as it turns out. An ivermectin dose for horses can be as high as 1,200 milligrams, according to Scott Phillips of the Washington Poison Center in Seattle. "It's really the dose that makes the poison," says Phillips — even too much tap water or salt can be poisonous. With those considerations in mind, consider how CNN framed Rogan's use of ivermectin. *On Sept. 1, CNN host Erin Burnett said: "Controversial podcast host Joe Rogan, who's railed against vaccine requirements, says he has covid and took a drug intended for livestock." She articulated similar descriptions two additional times before interviewing a doctor and noting that the drug is prescribed for people as well. *The same day, CNN host Anderson Cooper said, "One of those drugs he mentioned, ivermectin, is something more often used to deworm horses." On that same show, CNN chief media correspondent Brian Stelter said, "When you have a horse deworming medication that's discouraged by the government that actually causes some people in this crazy environment we're in to actually want to try it. That's the upside down where we're in with figures like Joe Rogan." Leana S. Wen — also a Post contributing columnist — later added the critical context that the drug "is used in humans for things like parasites and scabies." *Also that day, host Don Lemon said, "The United States is now averaging 160,455 new covid-19 cases every day, including controversial podcast host Joe Rogan saying that he tested positive for covid and that he says he is taking several medications including a drug meant for deworming livestock." *On Sept. 3, CNN political commentator Bakari Sellers said, "I think the unfortunate part about all of this is you have individuals like Joe Rogan, for example, who don't want to take an experimental vaccine but will take horse dewormer." *And on Sept. 4, anchor Jim Acosta played Rogan's disclosure video and said, "In case you missed it, Rogan said ivermectin. Yes, that's the deworming medicine made to kill parasites in farm animals and, weirdly, is being promoted by right-wing media figures and even some politicians as a covid treatment." There's a reason for reciting these transcripts. They turn up a consistent formulation from multiple CNN voices that surely wasn't a sober recitation of the facts. By highlighting that ivermectin is a horse dewormer, and downplaying that ivermectin has important uses for people, CNN facilitates a certain assumption among its viewers.
