How has biosecurity/pandemic preparedness philanthropy helped with coronavirus, and how might it help with similar future situations?

My understanding is that Open Philanthropy's biosecurity and pandemic preparedness focus area is intended partly to target situations like the ongoing coronavirus pandemic. Though biosecurity philanthropy hasn't caught on a lot in the EA community at large, it has attracted some commentary and thought in the community. I'm wondering a few things:

• How has Open Philanthropy's biosecurity/pandemic preparedness philanthropy so far affected the way people have dealt with the coronavirus pandemic?
• How might the biosecurity/pandemic preparedness philanthropy affect similar situations in the future? Is it laying the groundwork for improving how we address such situations in the future?
• Are there any learnings so far from the coronavirus pandemic, for what to focus on in biosecurity/pandemic preparedness philanthropy?

Some of these questions may be better answered after the coronavirus pandemic settles down.

Thanks to Issa Rice for hearing out my original version of the question. He did not review this post.
