I'm not sure why you say "price tag is low". It's not low at all, and it's totally avoidable at the cost of a few thousands shots. In the age of medical system underfunding (or in any case, affected by cuts) the health management must look at every avoidable expense, and IC beds are quite some expense. Add to that the increased predictability of a vaccinated population and you have the winner option. I'm only talking money here, and I'll leave the societal and personal implications for others to look at.
