FYI for those who don't know: QALY is Quality Adjusted Life Year. Parent is right that it's problem the best metric to use. I believe that we aren't using it because we don't know the morbidity that results from Covid-19. In other words, we don't know how Covid affects people's long term health. Someone might survive the virus, but end up having long term lung or liver or whatever damage. That reduces their capacity to work and may reduce their lifespan, i.e., their economic output after the life-saving intervention is reduced.
