During the hearings, Kennedy asserted that he advocates for more rigorous safety testing rather than opposing vaccinations outright. His previous affiliations as head of the anti-vaccine organization Children’s Health Defence came under scrutiny, particularly under the lens of Senator Bernie Sanders, who exhibited merchandise promoting anti-vaccine sentiments that once bore Kennedy's organizational imprint. Nevertheless, Kennedy's testimony gained pivotal support from Republican Senator Bill Cassidy, a physician who had previously been critical of Kennedy's nomination. Cassidy's endorsement notably helped navigate the way for a full Senate vote.

As Kennedy prepares for the larger Senate vote, he is positioned to oversee critical health agencies like the CDC and FDA, including suggesting significant staffing changes within these organizations to align them with his reform ideas on healthcare and food safety. Although there may not be sweeping bans on vaccinations or unhealthy food products directly from Kennedy if confirmed, he plans to target the usage of certain food additives, which he claims are more permissively used in the U.S. than in Europe. With his unique background as both an environmental lawyer and a controversial public figure, Kennedy's health policies could make substantial waves across American healthcare.
