A "both-and" approach (both prayer and medicine) to physical and mental health has been attributed to Williamson. This approachthe efficacy of prayeraccepts medical science as part of God's power to heal. For example, surgery may be seen as God answering prayers to heal. This logic invokes what Johns Hopkins Medicine has called the "strong link between 'positivity' and health", in which "positive attitude improves outcomes and life satisfaction across a spectrum of conditions." Williamson, who believes that "the spirit is impervious to illness," confirmed this belief when she said that "people who are prayed for get out of the emergency room faster" and "people who have been diagnosed with a life-challenging illness, who attend spiritual support groups, live, on average, twice as long after diagnosis." She maintains that prayer is complementary to medicine, not a substitute for it. Williamson has stated her support for the necessity and value of vaccinations and antidepressants, but has been criticized for her skepticism about the pharmaceutical industry's influence in setting guidelines for how they are administered, citing her belief that their profit motive could result in harm to patients. She has also been scrutinized for criticizing overprescription of antidepressants, questioning whether antidepressants play a role in suicide, saying that the prescriptive definition between sadness and clinical depression is "artificial," and having called the process by which clinical depression is diagnosed "a scam." 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 point 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." Williamson has expressed frustration that her skepticism of the pharmaceutical industry has been equated with skepticism of the science of vaccines. She
