I think it quite insane to be giving it to pregnant women first and foremost! Personally, I make it a habbit not to try anything FDA approved till it has been on the market atleast 4 years (10 preferably!) since they are ALWAYS recalling FDA aproved medicines because they're killing people or doing permanent damage.
Aside from that, I think the swine flu is another overdone issue. It is a mild to moderate flu like the ones that pass through our communities often, I have yet to hear of it killing someone who hasn't had serious underlying conditions to begin with, and YAH, pregnant women are WAY more likely to need to be hospitalized with ANY flu, not just swine flu.
I'm not anti-vaccine, but I do believe in letting my own immune system handle what it can, and in not overloading a budding one (inutero or newborn) with toxic chemicals so that they can be "protected."
