Thanks for the opportunity to respond to that question.
I would suggest that documentation and maintenance of that documentation over that century, while somewhat challenging.... Certainly we were able to look back to more recent lessons, specifically through the H1N1 experience and to roles there. There were some lessons learned but it was suggested that, again, we were looking at more of a known entity in an influenza, with H1N1. There's much more uncertainty with this pandemic, being the first-ever coronavirus.
