This always takes me down a rabbit hole to get hopefully correct info lol.
I'm no law man, but on the surface it would appear that section relates to the
issuance (specifically) of an MCM under EUA, as it can be found in section III.B.1.d of the
FDA's guidance document under Criteria for Issuance. So, "for FDA to issue an EUA" for a given MCM, that criteria must be met (along with additional criteria is sections a-c).
However, there are additional sections that cover how and when an EUA will end. Section III.G of the guidance document, titled Duration and Revision of an EUA states:
In general, an EUA will remain in effect for the duration of the EUA declaration under which it was issued...
Hopefully that is good info. I wouldn't want to mislead!
