Breaches of trust? You mean news about companies losing personal data? That has absolutely nothing to do with vaccination, or global warming, or other things. And people should not distrust experts on matters like that because of nonrelated matters, but they do. That’s the problem - people conflating things that are not even in the same ballpark.
Of course nobody can make another person’s decision. But making decisions about a child’s health and other important matters because of general distrust over nonrelated matters is insane.
