Age-Targeted Dose Allocation Can Halve COVID-19 Vaccine Requirements

  • [Pre-print, not peer reviewed] An age-structured mathematical model investigating age-specific allocation strategies for SARS-CoV-2 vaccines indicated that across 179 countries, the highest priority individuals for vaccination were typically those 30-59 years of age, based on their higher risk of infection and disease, and greater rates of contact. The model assumed that the vaccine would be 70% effective, and that there was age-dependent susceptibility and disease severity. The authors estimate that optimizing how the COVID-19 vaccine is allocated can more than double its impact in reducing SARS-CoV-2 transmission for a fixed number of doses.
