It’s the first meeting of the Advisory Committee on Immunization Practices (ACIP) since Kennedy fired all 17 members and appointed eight new panelists, several of whom are vocal vaccine critics.
As part of its scaled-down two-day meeting beginning Wednesday, the committee is set to vote on influenza vaccines that contain thimerosal — an ingredient wrongly linked to autism.
Kennedy has long advocated for banning thimerosal, a preservative that was widely used for decades in a number of biological and drug products, including many vaccines. In his 2014 book, Kennedy said thimerosal was “toxic to brain tissue” and likely caused autism.
Thimerosal, a compound that contains mercury, is used as a preservative to prevent harmful bacteria in multidose vials of vaccines. The compound has been largely phased out as manufacturers have shifted toward single-use vials that contain little or no thimerosal, according to the Centers for Disease Control and Prevention (CDC).
Thimerosal was largely removed from pediatric vaccines by 2001, amid concerns that it could be linked to autism in children. But according to the CDC, “a robust body of peer-reviewed scientific studies conducted in the U.S. and other countries support the safety of thimerosal-containing vaccines.”
The draft agenda for next week’s ACIP meeting revisits issues that scientists and public health experts have long considered to be settled, including the use of the measles mumps, rubella and varicella vaccine in children under 5 years old.
It’s unclear yet what the panel will discuss regarding the shot.
The current CDC childhood vaccine schedule recommends two doses for children, with the first dose at age 12-15 months and the second at age 4-6 years. CDC suggests that the MMR vaccine be given rather than MMRV for the first dose, but both shots have been on the schedule for decades.
