Can you tell me in the usa, which infant and childhood vaccines contain thimerosal (mercury)?

No routine vaccine: None of the licensed pediatric vaccines contain thimerosal except for multidose influenza vaccine - the single dose forms of influenza are thimerosal free.

None: There is no thimerosal in any childhood vaccines in the US. It is occasionally in the annual flu vaccine. And whether it is or not, children should still get the annual flu vaccine. Despite what the media and internet hype proclaims vaccines have a long record of safety. The risk benefit ratio cannot be ignored.
