Interesting thing about COVID-19 vaccine is the world is going to need as many of them as can be produced, by as many manufacturers as possible. Just like with the flu vaccine. No one manufacturer has the capacity to supply the needs of the US, much less the rest of the world population.
Nobody knows squat at the moment, and to suggest otherwise is misleading. Never put your eggs in one basket.... the same goes for MNRA. All i know is Korea is signed up and Australia is soon to follow.
