Insulin sold today is not the same bovine insulin that was originally patented 100 years ago. Insulin needs to be affordable, but the trade-off we’re seeing (and that comments like this leave out) is that insulin development continues to move forward, with the new stuff being significantly better than what came before it. The $25/vial no Rx stuff at Walmart requires much more discipline and attention than the stuff that is hundreds of dollars per dose. This is the market sending signals that better insulin is worth developing.
