Trillian - Not worried really, but its just a scary thought and this book has got my mind ticking. To think we could be endangering our children with these vaccinations, it worries me because I've always thought I'm doing the right thing getting her vaccinated, but then you hear these stories from parents of autistic children. Do you worry at all that Alister may pick up a bug down the track from not being vaccinated? Did you vaccinate all your other children? I guess I just feel very uninformed about it all...
