Possibly those things could help, I guess it remains to be experimentally determined. Anyway it's a decent proof of concept paper, although the in vivo data is a little weak.

Btw, they are giving a lot of doses already, every day at lower viral titers, and every 3rd day at high titers up to two weeks. Then they cut the experiments two weeks after that so we don't really get a good sense of how things would fare longitudinally but I can tell you from having read a lot of these papers that all of those mice will die pretty close to the controls, probably delayed by only a few days or a week.

I dont mean to be negative, as I can sense you are excited by the possibilities this strategy brings up, just trying to inject some realistic perspective into the data they show.
