The only thing this highlights is the production issue that Ms. Ravon just mentioned. I think it's unprecedented for everybody around the world to want to have a vaccine at the same time, so this is really making production an issue, and it's really going to be difficult this year to produce enough vaccines for everyone.
Then there's a political issue. Obviously, a number of countries are prioritizing vaccinating their domestic population first because they are under intense political pressure to do so, especially in western countries. In the European Union, all the debates in all the newspapers at the moment are all about whether the vaccine rollout is fast enough. In this situation, it's very hard to imagine that the European Union will allow large quantities of vaccines to be exported abroad in the coming months. As you mentioned, Italy has blocked some shipments of AstraZeneca vaccines to Australia, so it's not impossible to imagine that this could happen again.
Again, this really highlights two issues. The first one is production. There is a need to ramp up production to be able to vaccinate everyone this year. That's not going to be possible. The second one is that this has become a very political topic.
