As someone who was born and raised in America, the idea of a making a vaccine exclusive to the U.S. is morally repugnant, disgusting and outrageous. I hope that this doesn't come to be in this way. Any vaccine developed for COVID-19 should be free and shared with everyone regardless of income or geographical location. That is the only sane and compassionate thing to do. I hope more details emerge about this.
The Guardian (British): "This is the case for Moderna and another Boston company, CureVac, both of which are building Covid-19 vaccines out of messenger RNA."
So now it's a Boston company? According to Wikipedia the one in Boston is just a subsidiary.
