You are not paying attention. The single-dose versions that were targeted at administration to children explicitly do not. The nasal inhalation version that was targeted for pregnant women explicitly does not. The multi-dose vials are the ones that contain Thimerosal, and those are explicitly NOT for pregnant women nor young children.
