How did you think science worked if not like this?
Everything we consume we have "safety tested" by trial and error - including all natural foods. Obviously a lot of that was done in pre-history, but the same principle applies.
Personally I'm thankful scientists continue to work to make vaccines more effective and continue to extensively safety test them.

Policy makers, however, present a dumbed down, black and white view: this is how it is, we know what we're doing, no need to ask questions.
It is interesting, therefore, to read a mainstream article which discusses a fundamental lack of understanding, on the part of scientists, of how these chemical cocktails operate in the body.
What did you think I meant if not this? Personally I find it offensive when someone responds to every move of big moneymaking drug developers by clapping their hands and chanting, "oh, isn't it sooo reassuring!!!" But that's just me.
"genetically altered a dangerous bird flu virus to make it more contagious in mammals" There's always a neat and tidy spin to these experiments, so naturally we must accept them, no questions asked.
