Aaron Siri is helping Trump’s health secretary pick to select top jobs despite long history of attacking vaccines

A key legal adviser to Robert Kennedy Jr, Donald Trump’s pick for health secretary, is at the center of efforts to push federal drug regulators to revoke approval for the polio and hepatitis B vaccines and block distribution of 13 other critical vaccines.

Aaron Siri, a lawyer who has been helping Kennedy select top health administrators as part of the Trump transition process, is deeply embedded in longstanding efforts to force the US Food and Drug Administration (FDA) to withdraw a raft of vaccines that have saved the lives and health of millions of Americans.
