Thanks, I'm not talking about the difference in the EUA and the Approved versions. I'm talking about the clinical trial vs all subsequent versions with regards to how the actual vaccine genetic material was produced.

I can't find the reference at the moment, but I believe they used PCR to replicate the mRNA during the trials, and used the bacteria replication for the subsequent versions.

Here's a professor giving testimony to his findings: https://www.youtube.com/watch?v=IEWHhrHiiTY
