Follow up on my flu shot question further down

Hi everyone,
I got my flu shot today at CVS. I asked about it being thimerosol (sp?) free, so the person there looked at the insert and it said that it had 25mcg of mercury, but didn't mention thimerosol(whereas the multidose vial that they use sometimes says thimerosol).

She said the one she gave me was the one given to other pregnant women.

Please tell me I got the right one!

Thanks,
