A member asked:
Which vaccines contain thimerosal? what are egg protein and formaldehyde used for in vaccines?
A doctor has provided 1 answer
Flu - but no worries: Only (some of) flu vaccine contains thimerosal. It and formaldehyde are to inactivate bacterial toxins and 2 kill any contaminating viruses/bacteria. Some worry that thimerosal causes autism; however autism continues to increase despite removal of thimerosal from vaccines in 2001. Most formaldehyde is removed during processing, and egg proteins are there cuz some vaccines need 2 grow in eggs
