I think the challenge here is really not with the European Union. They have been doing everything we have been asking them to do in terms of ensuring that we would be getting any deliveries that we would be expecting, and we have not had interruptions as a result of that.
The difficulties we've faced have been more at the company level and difficulties in production. Some setbacks have occurred. We're now getting lots of vaccines coming from Pfizer. They seem to have resolved most of their production difficulties. Moderna is still experiencing some, but is also coming back on track. With an operation of this scale, I think we can anticipate that there will be some production hiccups from time to time. That's what we have faced, but we now feel we're very much on track.
