In a resurfaced 2015 Fox News clip, Greg Gutfeld passionately defended vaccines against Donald Trump’s claim linking them to autism, deeming Trump’s perspective “hysterical anti-science” and dangerous. Gutfeld criticized the use of anecdotal evidence, arguing it misrepresents scientific causality. Fast forward to recent times, Gutfeld has embraced Health and Human Services Secretary Robert F. Kennedy Jr., despite Kennedy’s controversial stance on vaccines, reflecting a shift in Fox News from skepticism of Trump to alignment with his views. Gutfeld praised Kennedy’s debating skills and open-mindedness, suggesting he would support his cabinet position despite acknowledging Kennedy’s reliance on “gut instinct” over science regarding vaccines. This shift signifies a broader transformation within the Republican Party towards vaccine skepticism.
