Ed Rybicki's insight:
...and hep A steals membranes from liver cells to circulate as an enveloped particle(s) in blood. This is a fascinating find, and doubtless will be followed by similar for other viruses.
The commentary has some speculation as to how vaccines work, if antibodies can't see the virus - but they forget the virus has to get INTO the host in the first place, and environmental forms are non-enveloped, AND that the vaccine may well elicit some degree of cell-mediated immunity, which would target infected cells displaying degraded protein on their surfaces via MHC I-type receptors.
