I would say SII is pretty capitalistic. Its charging $8/dose in India vs $3-4/dose that AZ is charging in US and EU. And that is before any markups in public hospitals from what I hear. And remember SII got $250M from Bill Gates and didn't have to do vaccine development like Oxford/AZ. The Covaxin vaccine developed in India is even more expensive but they had to do their own development.
