This is a food safety issue and a lot of the results depend upon the way the meat was handled, smoked/cooked, and the temperature of your refrigerator. Vacuum sealing definitely extends the shelf life of cooked/smoked meat but poorly handled food can actually increase the dangers. 5-7 days for properly handled food should be no problem at all. Some sources say vacuum sealed, cooked meat can be kept in a cold refrigerator for up to a month. Do I recommend that? No, because there are bacteria that thrive in low oxygen, low temp environments where spoilage bacteria do not thrive. The problem is the anaerobic bacteria do not give off any smells, tastes, or signs that the meat is unsafe to eat.
I'm a fanatic about washing my hands and prepping food in a sanitized "clean zone," avoiding cross contamination when handling raw meat before it is smoked. Once smoked and properly through the "safe zone," the same attention to detail is exercised when prepping for serving. Personally, in the coldest part of my fridge which runs 34F, I've gone longer than 5-7 days with smoker roasted vacuum sealed meat just testing how long I could go. It was still perfect at 3 weeks but I could not bring myself to go any longer than that.
Now, if you happen to have a cobalt 60 irradiator handy, you're good to go for years!
