So it kills the cells that have the virus active... and then? There would still be virus particles the bloodstream, and suchlike.
Also, what about re-infection?
It's intended to used as a vaccine, not a cure, because of issues like that. It'll
work, but cause a lot of damage as it kills off every cell that gets infected in its
eight day effective lifespan, which means sizable inflammation of vital tissues. I imagine the immune system cleans up the bloodstream in the meantime; they did wait to see if re-infection occurred, and it didn't.
What's
supposed to happen is that it's taken when there's a serious infection
risk and it kills off the initial infection, before there's
any chance to replicate. Safe passage of contaminated areas (say, a week's vacation in China right now) and shutting down outbreaks by using it to
immediately get herd immunity going.
