The vaccine for H1N1 (swine flu) apparently has Thimerisol as the preservative, which is more mercury than is safe to ingest by our FDA standards, for say, tuna.
I don't trust the results of the studies done by the pharmaceutical companies that claim their preservative has no link to autism. One court already awarded some parents who happened to have a lot of information on their child's health before & after receiving vaccines, who then was diagnosed autistic.
Since we don't fall into the high-risk categories, and the current strain of H1N1 does not appear to be as bad as last year anyway, we won't be doing a flu vaccine. We will continue to eat healthy, exercise & get enough rest. We will wash our hands a lot, and stay away from sick people as much as possible.
The latest counts I saw were that the 'normal' flu has more deaths attributed to it than swine flu. Since we typically don't even get THAT flu, I think we're okay.
I'm going to guess a lot of parents of kids with autism do not go get vaccines anymore either.
