Did the US COVID-19 vaccine strategy work?

The CDC's four-tiered vaccine prioritization strategy outperformed most approaches in reducing deaths and cases, while some optimizations could improve outcomes. The study found that prioritizing healthcare workers and individuals under 16 was optimal, but strategies focusing on comorbidities were also effective.
