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.

If the CDC adopts the recommendation, it will mark one of the first major changes in federal vaccine guidance and access as Kennedy embarks on his goal of remaking immunization policy in his image.

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.
