I wonder how many high school chemistry teachers could figure a way to get insulin stock from local pig farmers. I know that sounds like a bad TV show, but the original Type 1 insulin came from a guy who synthesized it from pigs.
One has to wonder if the “knowledge” is still out there. Talk about a corner on the market if you could find someone who could do this.
I assume more could be imported from countries not affected
