On that note, from the very beginning China's reaction appeared extreme and overbearing, but in hindsight it worked better than most other countries' responses. The question is... if other countries had known that it was from an accidental leak would they and the population in general have taken it much more seriously? I think they would have. If it were proven to be from a leak would there be less vaccine hesitancy? I think so too. The strongest contrarian argument against doing anything was always "it's just a flu" and some variation of "let nature take its course."
