Some of the protocols that are in place are sensitive by their nature, and therefore, I'm not at liberty to necessarily disclose them in detail. What I can say is that we look at security through a number of lenses. That includes physical security, it includes human security, it includes biological security and it includes informatic security. All of those are overseen and reviewed on an ongoing basis to ensure that they are fit for purpose and that they are meeting the needs of the evolving environment.
That process has been assembled under what we term our science excellence initiative, which includes other aspects, but security is one of the core aspects of that initiative and it is work that is ongoing since the work is never done in this space.
