I really don't know if it has traces of mercury. My sister has inflexal. I was worried about what she was having so found that article. She has one every year because she has bad asthma and has an inhaler so they give her one every year. They also wanted her to have pneumonia, but she refused that one as it made her sick one time.

Is "thiomersal" the ingredient that contains mercury?

I found a vaccine called vaxigrip that is thiomersal free, so I thought this one may be mercury free. Any thoughts? Aventis Pasteur is the manifacturer which was on your list.
