I have a few questions before we conclude. A few issues struck me during the meeting. The virus has been changing and there are different variants and so on. This may be an obvious question, but is there a process whereby the vaccines will at some stage be changed to strengthen people's immune system against the latest given variant? How long will that take and what is the process? At what stage will the various companies respond with a modification of their vaccines?
