Her daughters (and sons) will retain the protection transmitted to them.
The offspring of the superceding queen would not enjoy that protection
(except transiently, through 'herd immunity'), as the supercedure cell
would not have had any loading of AFB proteins into the royal jelly fed to
the developing queen. The herd immunity would disappear as the bees who had
the vaccinated queen as a mother aged and died, and the hive's population
shifted to be all offspring of the superceding queen.

The feeding of royal jelly to the queen (as a larva) that contains proteins
derived from killed, non pathogenic AFB are how that new queen would be
'vaccinated'. It sounds as though this might be available to you, given
statement #3. It is not something that I could do with queens I raise
myself (unless I were able to buy the requisite killed AFB proteins and
followed the procedures for feeding them to the nurse bees that will feed
royal jelly to larvae in the developing queen cells).
