For now all one can say is transmission is assumed to be dramatically reduced.

The bigger risk is likely that in some the suppression is temporary or transient flares of replication under some circumstances.

The other question is, does this avoid all the sequela of HBV. It seems to reduce risk of cirrhosis atleast.

For hiv, it took many decades to be able to make the clam undetectable = untransmittable using serodiscordant couple studies.
