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.

You are incorrect: In the US, two 2009 H1N1 vaccines distributed in multi-dose vials were approved for children >= 6 months. See:

This is correct. And we had it administered to our then 14mo old son. He's fine.

Hooray for meaningless anecdotes!
