I'll briefly finish off.
Clearly, in this pandemic, if you're seeing the first cases in the world, it's a different issue. Once it's established, which it was—well-established by then—early treatment is key for those who are most vulnerable, and remote communities are vulnerable. That's why antivirals are pre-positioned, so that early treatment can take place. And we've noticed a major difference in the impact, once this has been implemented.
On the issue of updates, there really hasn't been much change since July; things are updated as changes occur and develop. The guidelines around vaccine are being developed currently—that's for everybody. They need to be in place before we actually do immunize, but they don't need to be as of today.
