it was about decreasing the surge of cases that would lead to hospitalizations, and now fast forward almost two years, and we're really talking the same thing. i know that we seem to kind of be jumping around whatever the shiny object is in front of us in terms of where our conversations go, but the emphasis remains and needs to remain on what hospital capacity is in a given community, in a given state in, a given region of the country and really those are the important numbers. they also really have an important impact in terms of what we think about when we consider what we want our advantages opens and our boosters to do. if we want our boosters and vaccines to prevent every runny nose, we're not going to be successful with that. that's asking too much of any vaccine, but if we want the boosters and the vaccines to keep people out of the hospital and to keep them from dying, we really have very good news to consider, certainly better than a yore ago when we were just rolling out vaccines in the first place.
