Mrna technology was already existent and Moderna began work almost immediately. Once the Genome had been supplied it was relatively easy to fabricate a vaccine so long as you weren't to careful to look closely at it ie: Warp Speed
This was same folks (China) who were still lying regarding the source of Covid namely the “wet market. Their data was accepted virtually without question. I can find no where Kochs’ postulate or Bradford Hill criteria were used to prove that what the Chinese supplied was correct.
