Opening the first meeting of Kennedy’s handpicked seven-member panel, committee chairman Martin Kulldorff said he was appointing a work group to evaluate the “cumulative effect” of the children’s vaccine schedule — the list of immunizations given at different times throughout childhood.

U.S. Health Secretary Robert F. Kennedy Jr.'s newly reconstituted vaccine advisory panel said during its first meeting on Wednesday that it would study the schedule of childhood and adolescent immunizations and review the use of older vaccines.
