An object would be Thread-Unsafe if it is stored as Member/Static Variable in a class whose different methods are invoked in different Threads.
Is this what we mean when we say that Vector is Thread-Safe?
Does it help in any other scenario as well?

No, an object is thread unsafe when it is a shared resource amongst competing threads and no synchonisation and/or semaphores are implemented. Vector is thread safe, because when some thread is reading the vector, another thread cannot come and modify the same vector. As I said before, it helps for ANY shared resource, be it file I/O, Database connections, etc.
