"I just wish that no more children have to suffer before the extent of the damage is realised"
I wish the same. The difference is that I think that the best way to reduce the suffer of the children is to improve vaccination. More studies on safety are always good, but how much studies are enough? The more we wait until we consider a vaccine is safe, the more people dies for the virus until the studies are completed. A 30 year study should have made before starting massive vaccination of smallpox? How much people would have died in that period of time?
I agree about every person should always have right to choose, and that right includes the right to be properly informed about that. I try to inform the people the best I can. Most anti-vaccine arguments are false or can be misunderstood, and this I was tried to show in that conversation. I am not telling that all the arguments are wrong, of course.
As far as I know there is no different sizes of vaccines according to age, but the limits in some ingredients like aluminum and mercury are more strict for children and babies.
