Any anti-vaccine activists worth their weight in salt will tell you that thimerosal is ultimate evil because it contains mercury.

One is excreted from the body; the other is accumulated.
To further embarrass themselves, anti-vaccine activists will tell you that vaccines contain formaldehyde, and formaldehyde is all sorts of evil. The problem with their fear mongering over formaldehyde is that the amount of formaldehyde in vaccines is incredibly small. In fact, we make more formaldehyde in our cellular reactions in one day than that in any vaccine. Because of this whole natural selection (evolution) thing, we are able to metabolize formaldehyde into things that don’t hurt us (thank God!). The only time formaldehyde is a problem is if you ingest a quantity much larger than what you’re able to deal with.
This is the case with all ingredients in vaccines. Yes, they have scary names, but, no, they won’t do anything to you.
