Generally, this is not correct on two accounts:
* Vietnam nationals do not need visa for airside Schengen transit in any of the airports - so blanket statement on transit visa is not appropriate
* US visa denials have very little bearing on EU visas issuance (which are usually much easier to obtain). Obviously, having no idea about the grounds of those denials I can't predict the outcome, and the same grounds could preclude EU visa as well - but US denial by itself is not a factor.
