Coaxin is a transitional vaccine already approved in India (I took it). But yes they haven’t got EUA in US and WHO still hasn’t approved it yet.

I too see some corporate competitive politics behind Novavax - Serum Institute of India (SII), one of the largest manufacturer of vaccines in the world, had been licensed to manufacture Novavax in India last year, but apparently the US administration held it up by preventing exports of the raw material with their "US first" policy. That's kind of understandable, but even in the US, I don't think Novavax is so easily available (or perhaps it is but the US media is excessively giving attention to only the mRNA vaccines from Pfizer and Moderna?). Even recently, SII said they are in talks to start production of Novavax this year, but it's still not available. It's not clear what is going on behind the scene with this particular vaccine.
