Maybe I'm being naive, but why would any country, for any reason, try to conceal the process of developing a vaccine? I personally think about 99% of "secret" stuff, classified stuff, shouldn't be, and vaccine development would certainly fall in the 99%. If the US develops a vaccine, and somebody in India "steals" it and saves a few million lives with it, more power to them. I think every step of vaccine development should be published on public forums for everybody to see and use if they can. Pretending that this is a "war" that somebody can "win" is nonsense, but not harmless nonsense.
