The United States has announced three measles-associated deaths over the past week. The victims include a seven-month-old baby in New York and a woman who recently gave birth in Pennsylvania.
The deaths have added weight to calls for a more forceful vaccination approach, yet national recommendations have not been revised.
Four former advisers say that dismantling the Advisory Committee on Immunization Practices (ACIP) has made it harder for the US to respond to the outbreak.
They argue that vaccine recommendations have remained the same even as cases and deaths have climbed to historic levels.
