I'm struck by how little we've learned period. I hope in a position to think about this as a moment in history rather than an ongoing problem. What do you think is the biggest lesson from the pandemic that we have failed to learn as a as a world? That really backfired. We saw what happened when it was viewed as a Trump vaccine, the Democrats were saying they never take it and then when it became a Biden vaccine and the Republicans wouldn't take it. It should have been less to Madison Avenue who knows how to reach people in their heterogeneous populations we have.
