Imho you’re underestimating the impact of the disease in general. Disease is much more than who lives or dies, there’s also people who “survive”. A number of asymptomatic covid patients have severe lung damage. Vaccinating “at risk” people who might die doesn’t account for all the people who might live permanently disabled lives as a result of a covid infection.
