Whooping cough is caused by bacteria (Bordatella pertussis). It is virtually unheard of for whooping cough to re-activate, catching it again as a new infection is much more likely.

Incidentally, there is a zoster vaccine that can prevent shingles[1]. If you have ever seen anyone with the debillitating pain that shingles can cause, you will realise that this vaccine is definitely worth it.
