Ignoring parents concerns also makes Medical staff, Government agencies and Flu manufacturers seem either corrupt or incompetent. For example:

A multitude of web sites and parenting magazines either question or simply warn parents against using vaccines that contain metals. It doesn't matter how many condescending, snide or rude comments people make about that fact,
that kind of response only bolsters the resolve of a concerned intelligent person over the truth of the claims made about vaccines and safety.
Commentary made here is actually illustrative of the lack of understanding some people have about the fears and concerns a lot of parents have about vaccines. Even if you are correct, and mercury, aluminum and other toxins aren't really toxins when injected into kids, you won't change anyone's mind by anything other than real science.
There is no science at all to back up using mercury, for any reason. Mercury is an economic factor, not a medical one. It is not needed, does nothing to improve a vaccine, and there is nothing anyone can say that will change that fact.
Why would anyone choose a mercury vaccine when it isn't needed? At this point, no amount of "evidence" will convince people that mercury is OK to use. Why would any intelligent aware parent believe you? Why take a chance? When you don't need to?
Only because mercury free vaccines aren't available. Even then, do you risk some unknown side effect or risk the flu?
Evaluating risk, questioning facts, investigating the issues, doubting people who just make claims, these are all skeptical activities.
