ATLANTA (AP) — U.S. Health Secretary Robert F. Kennedy Jr.’s new vaccine advisory committee backed another option to protect infants against a dangerous virus — before turning to questions about fall flu vaccines and a preservative in a small fraction of them that some antivaccine groups have falsely tied to autism.

U.S. Health Secretary Robert F. Kennedy Jr.'s newly revamped vaccine advisory panel voted on Thursday to recommend Americans receive seasonal influenza shots that are free from the mercury-based preservative thimerosal despite decades of studies showing no related safety issues.

Dr. Levi and Vicky Pebsworth, a nurse affiliated with an anti-vaccine group, voted against recommending clesrovimab; the other five members voted yes. After some confusion, the panel also voted to include the antibody in the children’s vaccine program.
