"Because of the dramatic age-skew of disease, vaccinating the small number of very old people has an astonishing impact on mortality risk.
According to one assessment of the Israeli approach, which focuses on protecting the elderly first, vaccinating just the 0.5 percent of people over 90 drops the total fatality risk by 19 percent; vaccinating the 2.5 percent over 80 cuts it fully in half; vaccinating the 7.5 percent over 70, drops it by three-quarters.
Ultimately, Israel chose to bulk-vaccinate all those over 60, so the improvements are less dramatic than they might have been. But by late January, the country will probably have reduced its fatality risk from the disease about tenfold."
