The ACIP decision to discontinue the recommendation for a universal hepatitis B birth dose vaccine will cause harm.
As the federal government continues to fail children's health, families can rely on our nation's physicians to continue to put children's health first.

Friends, Yesterday and today, I watched many hours of the CDC’s meeting of the Advisory Committee on Immunization Practices (ACIP).
It was painful.
But we learned a lot.
That bad news is that our kids are going to pay the price for RFK jr’s views.
