Thimerosal is approx 50% mercury by weight - if you google this you will see that it has been highly controversial and as such is no longer in most childhood vaccines. Why they are still putting it in the swine flu vac that is recommended and administered to young children and pregnant women I'm not sure

If you would like to know about the swine flu ingredients or any other vaccine ingredients they should be listed on the WAVE (World Education for Vaccine Education) website. Then you can take the list away and do your own research. I think that is a better option than to ask those who are either anti or pro vaccines. It can get messy!!

Hope you get the answers you are seeking.
