The model suggests that by March 31, 2021, compared to age-based allocation, the proposed degree-based strategy could reduce an additional 56\u2013110k infections, 3.2\u20135.4k hospitalizations, and 700\u2013900 deaths in Virginia, or 3\u20136 million fewer infections, 181\u2013306k fewer hospitalizations, and 51\u201362k fewer for the entire US.
