Those trials are coming in, and it really relates to dose. The recommendation from our expert committee, because of seasonal flu, was that normally children who are under the age of 10 need two half doses in order to produce immunity. From the initial trials, it looks like maybe one dose will be sufficient. So that's actually good news, but you shouldn't wait to start protecting people until you know whether you need one or two doses. If you know you need at least one, you start with that, and then you make the decision about a second dose when you have that information, which is starting to come in now.
