Can you be able to brake with a vacuum leak in the brake booster?
If the vacuum leak is small, then yes the brake booster will still function well enough to assist the braking action.

It's wise to just replace the power brake booster with a new unit if there is an internal leak in it, to avoid an accident due to a loss of braking power.
