It's really very very simple. All the pharmaceutical companies have to do is discontinue all use of Thimerosal in their vaccines and publicly announce that they have done so and voila! No more reason for people to fear vaccines. But that will never happen because of money.
They did that in the US and most of Europe 15 years ago. The article you linked to talked about developing nations, whose vaccines still have thiomersal in them. Thiomersal is also still used in some versions of the flu shot.
I find it very odd that Mercury can be argued to save lives in this situation but heaven forbid a pregnant woman eat fish.

Chemical bonding matters in chemistry. Fish can concentrate mercury into methylmercury, which is very toxic to humans. The preservative used in vaccines is thiomersal, which has never been shown to be toxic to humans for the doses used in vaccines. Those are two very different things.
Then why does the controversy still continue? What's supposedly causing the autism now?
Thiomersal. Or aluminum. Or "too many vaccines."
