Each country can choose vaccines for its own population, and they can do this on the basis of the information that they have. We do not believe that this is a source of concern. If a country makes the decision to introduce a vaccine, it means they have done so on the basis of a dossier that they have reviewed. In the case of WHO, we take more time, because we have to take the responsibility to do this not just for one country, but for many countries. So, the level of scrutiny and documentation has to be at the highest level.
