Health Secretary Robert F. Kennedy Jr. is overseeing a large, internal research effort into vaccines, according to reporting that describes the work as a top priority within his department. The initiative continues even as Kennedy reduces his public criticism of vaccines, a shift described as being done under orders from the White House. The coverage characterizes the change as a departure from the more outspoken posture Kennedy previously maintained in public discussions about vaccines, while emphasizing that the internal program remains active and substantial. The New York Times reports that, despite the quieter public stance, Kennedy’s role includes driving or directing investigations and studies related to vaccines within the health apparatus. The two accounts focus on the contrast between public messaging and internal priorities, suggesting that the research effort is being pursued through departmental channels rather than through public advocacy. The reports do not provide detailed findings from the inquiry, but they portray the effort as broad in scope and embedded in the department’s work.
