Health Secretary Robert F. Kennedy Jr. defended his agency's response to a record-breaking measles outbreak during a Sunday interview [1].
The statements come as the administration faces increasing criticism over the public health agency's handling of the current outbreak. The Health Secretary's stance on vaccine efficacy is a central point of contention for critics who have questioned his leadership during the crisis [1, 2].
Speaking with CNN's Dana Bash on Aug. 2, 2026, Kennedy addressed the agency's management of the health emergency [2]. He sought to clarify his position on immunization and the specific tools used to combat the spread of the virus [1, 2].
During the interview, Kennedy addressed the MMR vaccine, which protects against measles, mumps, and rubella. He focused on the effectiveness of the medical intervention in the face of the current surge [1, 2].
"I have never questioned the efficacy of the MMR vaccine," Kennedy said [2].
The Health Secretary used the appearance to push back against claims that his personal views or previous statements have hindered the government's ability to contain the outbreak [1]. He said the agency's actions are appropriate for the scale of the health emergency [2].
“"I have never questioned the efficacy of the MMR vaccine."”
This public clarification represents an attempt by the Health Secretary to align himself with established medical consensus during a period of high public health volatility. By explicitly affirming the efficacy of the MMR vaccine, Kennedy is attempting to neutralize political and scientific criticism that his leadership might jeopardize national vaccination rates during a record-breaking outbreak.
