Yes, of course.
Your question is a very good one.
It's important to keep in mind that the patent problem is a false problem. This has been clearly demonstrated. It's not a question of patent protection. The reality is that in order to immunize and protect the entire population, it's necessary to produce vaccines quickly and then distribute them to countries that need them, at a price that suits their needs. That's what Pfizer has done. We've maximized our production through our production chains around the world and then ensured that we have a price range that meets the needs of the various countries. As I mentioned earlier, we have three price ranges. In our opinion, these were the best solutions to respond to the pandemic and eventually put an end to it.
So it's not really a question of patents. As we've seen so far, when the experts who have the production capacity and the scientists who develop the vaccines are allowed focus their efforts on that, the industry as a whole is able to produce quantities of vaccines that meet the needs we're currently seeing in this pandemic.
