I reject the basis of all your arguments thus far; that the decision for one child doesn’t hurt the other children.
It does, polio, and how it is spread is but one example of that.
You want to risk it for your kids, fine, I have no problem with that.
You want to infect my kids too? There’s an answer I want to see from you.
If your kids are vaccinated then they should never get infected so that argument is invalid.
Indeed the only people at risk would be the child and others like him who's parents chose not to get them vaccinated.
Or are you stating that vaccinated children can be infected anyway?
And in that case then what good are vaccines in the first place?
