I did read through your entire proposal, this is a legitimate question, and is not address in your proposal. It is definitely not the problem your proposal is aimed at solving.

The question posed is would an attenuated virus create a much short immunity reducing efficacy of the overall approach. It seems like the only answer can be we don't know, we'd have to look at that.

Exactly. His whole proposal is based on the assumption that an attenuated strain imuunizes enough people long enough. This has been possible in other diseases. But for example not the common cold, and not only because many different virus belong to that category.

So yes, I read your proposal. No, this is not addressed.

Yes it could create a shorter immunity, but the idea is to use the attenuated strain to drive the dangerous strain to extinction.

More fundamentally there are many questions that are unknown, but doing nothing until they are all answered it a choice that has a very high cost.
