Certainly a good approach if done right, and been mindful with the whole looming birdflu virus and it's spread amongst birds that will lead to an increased risk of human tranfer and equally mutation that enable that cross-over more easily. However, a thought about how antibiotics got used in animals and in many respects we have to admit - abused in their usage leading to decrease in how effective they are. So with that history in mind, certainly be prudent to vist that whole aspect cure/exposure. Maybe that early intevention at source may be better and I suspect it may well be as shifting the zoological landscape of fighting a virus's at a stage prior to human exposure. But that may well just see over time, more robust virus's that rise up thru evolutionary exposure to any vacine we put into the wild. So many aspects to look at. Just the whole leasons from antibiotics into animals and how that went is something we need to be very mindful of in not repeating as the possibility of solving a problem in the short/middle term and creating a larger threat longer term is something that can not be rulled out. One thing that I hope they do look at is having some kill-switch method, be it anothe virus that attacks the one they release. A fail safe.
