Booboostoo, I took an acceptable risk with my first child.
She ended up vaccine damaged (for information purposes, as it was asked about earlier, she too was vaccinated without my consent. Not as a teenager, but as a baby). I don't blame myself for it - as you rightly point out, I took an acceptable risk, based on the best information I had at the time.
Given her reaction, and other reactions in close family, plus health conditions within close family (and the way dd's vaccine damage presented, highlighting links with these health conditions) the conclusion we have come to, for our family, in our circumstances, is that the risk is no longer an acceptable risk for our subsequent children. The stakes have risen exponentially, and the risk/benefit ratio is no longer what it was.
As Pagwatch said, I (and all of the people I know who either do not vaccinate some/all of their children, or who vaccinate using a differentiated schedule) happily lined up for vaccinations when dd was a baby. Even at that point, when I was clearly happily lining up for the majority of jabs, I (and dh) queried the necessity of one jab, as we didn't think it was as necessary as was being made out, and rather than talking to us and engaging on whether it was necessary or not, the nurse just went ahead and administered and then turned to is and said 'there, it's done now, so no need for the discussion'.
Post dd's vaccine damage, the information available to me was different. There was a whole lot more stuff added in. The best decision now, on the information dh and I have available to us is now very different, because we have to take into account the higher risk of reaction.
