I don't think this has aged well. Theoretically it was an interesting idea but now we see that even in Israel where a big proportion of young people are now vaccinated, there still can be a great number of new covid cases. Fortunately hospitalizations and deaths are relatively very few but that's because the elderly have been almost 100% vaccinated. The main issue is that transmission still happens with the vaccine which means that superspreading events will be less active but will still happen. If elderly were not vaccinated they would succumb to illness and death. Maybe by QALY it would be net positive but I doubt even that.
