Here is a link to the FDA BLA APPROVAL for the covid vaccine. Notice several redactions. (b) (4)

Here is a link to a page that gives the definition to redaction codes.

https://www.archives.gov/declassification/iscap/redaction-codes.html

I only see one listing for the redaction code (b) (4) and it says:

3.3 (b) (4) Reveal information that would impair the application of state-of-the-art technology within a U.S. weapon system.

I tried to apply the redaction definition in the sentences it was used in to see if it makes any sense. What do You think? It seems to fit but what they are redacting seems to be lab locations and stability protocols.

Let me know your thoughts.

Stay safe my frens!!!
