Are Catholics allowed to entertain that the Old Vulgate might contains errors?

In Decrees of the First Vatican Council (1868) in Session 3, Chapter 2 "On Revelation", items 6-7 state: > The complete books of the old and the new Testament with all their parts, as they are listed in the decree of the said council and **as they are found in the old Latin Vulgate edition**, **are to be received as sacred and canonical**. These books the church holds to be sacred and canonical not because she subsequently approved them by her authority after they had been composed by unaided human skill, nor simply because they contain revelation without error, but because, being written under the inspiration of the holy Spirit, **they have God as their author**, **and were as such committed to the church**. I cannot tell if a Papal Encyclical is the same as infallible statements which are Fides ecclesiastica or ex-cathedra or if they contain such infallible statements. If not, it appears as though an encyclical statement still represents the end of theological debate, as per Pope Pius XII in Humani generis (which is a Papal Encyclical itself): > Nor must it be thought that what is expounded in Encyclical Letters does not of itself demand consent, since in writing such Letters the Popes do not exercise the supreme power of their Teaching Authority. For these matters are taught with the ordinary teaching authority, of which it is true to say: "He who heareth you, heareth me" (Luke 10:16); and generally what is expounded and inculcated in Encyclical Letters already for other reasons appertains to Catholic doctrine. **But if the Supreme Pontiffs in their official documents purposely pass judgment on a matter up to that time under dispute, it is obvious that that matter, according to the mind and will of the Pontiffs, cannot be any longer considered a question open to discussion among theologians.** As I cannot ascertain the difference between an infallible statement and a statement which closes a topic to theological discussion the question is: Given declarations in the encyclical of Vatican I regarding the Old Latin Vulgate (whether these declarations are dogma or not, I cannot tell), are Catholics allowed to entertain that this translation contains errors, considering that another Encyclical states that encyclical statements close their subject matter to debate?
