That doesn't mean they had adequate production capabilities. It may have taken time to get production up to an efficient level.
Two other factors to consider: when was cryogenic storage of vaccines/mRNA first done successfully, and when were mRNA gene therapies first developed? Assuming any of this holds water, including OP, that could help pinpoint when this might have been developed.
