John Oliver hasn't seen his staff in a year and will still be in the "void" of his home when Last Week Tonight returns Sunday

"I mean, each studio and circumstance is different, right?" says Oliver. "For us, I think it would have been great to be back in a studio, but I don’t think we feel like we can do that yet. So we’ll be in the void for who knows how long? Well, I guess until they can roll out the f*cking vaccine!" Oliver adds: "I haven’t seen my staff for a year! There are people who work for me now who I’ve never met! I think we were going to probably be practicing relatively extreme caution for a whole bunch of reasons. One, we’re in the position where it feels like we can do that and still have everyone paid. Also, a bunch of our staff got sick at the start of the pandemic, which I think also kind of means that I think intuitively, we are going to be extremely cautious."
