U.S. Health Secretary Robert F. Kennedy’s new vaccine advisory committee is meeting for a second day in a row. On Thursday, the committee is discussing fall flu vaccines and thimerosal, a vaccine preservative falsely linked to autism by antivaccine groups. The group also plans to vote on recommending a new antibody treatment for RSV in newborns. The seven-member panel, which includes vaccine skeptics, replaced the previous 17-member group earlier this month. Public health officials are worried that ideological decisions could make vaccines less accessible and more expensive for millions of Americans.
