I'm not sure why you say the Latin Vulgate is the first true Bible. It's simple another translation from the original languages into Latin. How's that any different that a translation into 17th century English (KJV) or 21st century English (NIV)? The only "true" Bible is what was originally written. As long there are human translators involved, there are no perfect translations - only our best attempts to communicate the original message into a language that the contemporary man can understand.
