DD did the work to create this great visual of the rates of hospitalizations by age group. The hospitalizations are lagged a week to account for time from case identification to hospitalization. Contrary to Dr. Osterholm’s belief, this chart indicates no change in the rate of hospitalization recently for younger age groups. At around age 40 through the middle age groups you do see a slight blip up, but really only going back to the rates prevalent in the fall. Also note that in the two older groups, rates appear to have swung up. That I believe is a clear vaccination effect. The people for whom vaccination is not effective are also very likely to be highly susceptible to infection and serious disease. I would expect that in a highly vaccinated cohort, we will see far fewer cases, but among those cases there will be some severe illness. It is an interesting question why in case bumps or waves the rate may increase. Could be that outside of those periods a lot of cases are not really infections, but false and low positives, which would make the hospitalization rate appear lower, could be that during a wave people have higher viral loads and more severe disease. But it really isn’t much of a swing.
