Not sure if you mean Nightmare mode or not, but I rarely play Vaccine unless it's on singleplayer. Too much of a risk of losing all my boxes and EXP on multiplayer to the team's mistakes or running out of time because of the increased difficulty.

But even on singleplayer, Vaccine is the mission I play the least now. The last time I did, I only made it with 30 seconds to spare, while five levels before level 48 (meaning no changes in what zombies spawned) I always finished with two or three minutes to spare.
