"How can it all of a sudden be okay, just because it is in a vaccine? How can one say for sure injecting all these known toxic chemicals and germs into a developing babies body and brain that it doesnt have a negative effect. Of course it does, if you think about it logically"
If you think about it logically, you'll realise that the amount is vitally important.
It's OK when the 'dose' is so low it cannot possibly cause harm. I imagine you, for example, eat foods containing the toxic elements sodium and chlorine every day. But know you can do so safely if you stick to the recommended dietary levels of common salt.
Conversely, it's possible to overdose on plain water.
It's terribly easy to scaremonger if you throw around chemical names without including the proper information about safe amounts.
