Seeing 200M as an upper bound and that the current excess deaths are around 21M from COVID, the prediction is "only" off by 1 order of magnitude. At most.
Though, uh, maybe all that research made pandemic possible in the first place. Anyway a miss by one order of magnitude on a virus that does exponential growth is really good but obvious prediction. Public policy should definitely plan to deal with outbreaks on this scale of death.
