The vacuum sealed meat can last for 4 to 7 days in the refrigerator before going bad.
The vacuum seal does help the meat last a bit longer than just putting it directly into the refrigerator and keeps the meat fresher longer.
But to keep vacuum sealed meat or any meats longer than 4 to 5 days you should really freeze the meat instead of just refrigerating it.
When you keep the vacuum sealed meat or any meat in the freezer it can last for 6 months to a year and sometimes longer.
Although if you don't use the frozen vacuum sealed meat within a year then it becomes less fresh although it's still very safe to eat as long as it doesn't smell bad.
