Jennifer McCarthy-Wahlberg (born 1972) first rose to fame as a Playboy Playmate of the Year in 1993 before pivoting to mainstream television as the co-host of MTV's hit dating show Singled Out (1995–1997). She went on to star in films like Scream 3 and John Tucker Must Die, co-hosted ABC's The View (2013–2014), and has served as a judge on Fox's The Masked Singer since 2019. Though she is the cousin of actress Melissa McCarthy, she is perhaps best known today as a prominent anti-vaccine activist, promoting the debunked claim that vaccines cause autism and advocating for unproven treatments like chelation therapy for her son. Medical professionals and journalists have repeatedly condemned her views—which she rephrases as "pro-safe-vaccine-schedule"—calling them "dangerous," "reckless," and "uninformed," and labeling her "the face of the anti-vaxx movement." Her career was marked early on by controversy when her "Catholic girl" Playboy pictorial caused an uproar in her Chicago neighborhood, but it is her ongoing, widely criticized vaccine misinformation that defines her modern public legacy.
