During Williamson's presidential campaign, several excerpts of her past comments have conflated her skepticism of the pharmaceutical industry's trustworthiness with an embrace of anti-vaccination dogma. As a result, she has been accused of being "anti-medicine" and "anti-science." She denies such accusations, saying they "could not be further from the truth." But critics points to Williamson's January 2012 interview on her radio show, "Living Miraculously," with Gwen Olsen, a 15-year veteran of the pharmaceutical industry who implied that she personally believed antidepressants could be dangerous and linked to autism. Critics also cite a podcast interview with Russell Brand in which Williamson, while speaking about vaccine exemptions, "glibly" described the process by which vaccines are mandated as "Orwellian" and likened the debate about vaccination mandates to the abortion debate. She later apologized, saying she "misspoke," and that the comments erroneously made her "sound as though I question the validity of life-saving vaccines."
