Pfizer developed their vaccine without government aid. They should be rewarded for their product development and it’s not clear whether they will be yet. The others got lots of gov $$. Too often there is public money supporting drug development but all profits go to big pharma. This issue is a bigger abuse of the public good than Joe’s slow support of sharing patents. The real prize would be dealing with excess profits in pharma overall. Insulin prices are a great example of this kind of abuse.
