pfizer is also involved in the testing, qc, data mining, and trials of the vaccine among tens of thousands of people from various socio-economic backgrounds, age groups, locations, races, ethnicities, etc. they also work directly with the cdc and fda for regulatory compliance, data submission, reporting, following up. these 2 major tasks for any new vaccine will easily cripple any small startup from reaching end game within a year. moderna is always behind pfizer in these 2 steps as it requires an established pharma to move quickly and with tremendous scale for any new vaccine or drug. product labelling, documentation and instructions alone require an entire department of sexperts. i can imagine engrish or chingrish being printed on biontech vaccines' documentation by fosun pharma.
