RFK Jr.'s Vaccine Firestorm: MAHA's Rise Fuels Backlash and Big Pharma Ties

Robert F. Kennedy Jr. BioSnap a weekly updated Biography. Robert F. Kennedy Jr. spent the past few days toggling between being lauded as a health reform hero and facing scorching criticism from media, government, and even his own supporters. He made major headlines after presiding over the high-profile Make America Healthy Again summit in Washington DC, where he stood alongside Vice President JD Vance, the NIH director Jayanta Bhattacharya, and celebrity guests like Russell Brand and Dana White. According to Nature, this gathering brought Silicon Valley longevity enthusiasts and anti-aging entrepreneurs to the table with biotech CEOs and government heavyweights, all crowing about MAHA’s rapid rise from fringe crusade to a federal health movement shaping Washington priorities. But while Kennedy basked in praise from Vance and the head of the National Institutes of Health for his disruptive ambitions, Fortune reports that behind the curtain, his coalition is fraying. Several ex-advisers and grassroots organizers aired grievances on podcasts and social media, accusing key Trump-era appointees and MAHA strategists close to Kennedy of betraying the movement’s goals. Kennedy took to X, formerly Twitter, to defend his team, urging his followers to focus on MAHA’s “extraordinary achievements” and “build our coalition instead of splintering it.” This spat reveals deeper rifts about collaboration with big tech and pharma, as original supporters bristle at biotech firms’ growing presence on the MAHA stage. On policy, Kennedy sparked a firestorm after Stat News and The New York Times revealed he personally ordered the CDC to alter its website language on vaccines and autism, undermining years of scientific consensus. The CDC now calls “vaccines do not cause autism” a “not evidence-based claim.” Senate health chair Bill Cassidy publicly disagreed, and though Kennedy insists he wants only to inform the public, health officials and media say this amplifies vaccine hesitancy and stirs division, an accusation echoed during his speech at the Western Governors Association in Arizona. There, according to KJZZ and AZ Central, Kennedy defended his anti-vaccine position and chronic disease focus, but gave few specifics about a $50 billion Rural Health Transformation Program many states are eyeing for relief. National headlines have flagged a growing measles outbreak in Arizona and Utah, potentially threatening elimination status for the US, intensifying scrutiny around his vaccine stances. Amid the drama, Kennedy and Trump made a rare joint appearance in the Oval Office to tout a deal with Eli Lilly and Novo Nordisk on cheaper weight-loss drugs, signaling a willingness to collaborate with Big Pharma despite his usual skepticism. Across social media, Kennedy’s base is abuzz: some tout his transparency, others worry his collaboration with corporate players could dilute his crusader credentials. As MAHA’s popularity soars in polls but old allies grumble, Kennedy finds
