Global impact of the first year of COVID-19 vaccination: a mathematical modelling study

🤖 Plain-English Summary

BACKGROUND: The first COVID-19 vaccine outside a clinical trial setting was administered on Dec 8, 2020. However, inadequate access to vaccines in low-income countries has limited the impact in these settings, reinforcing the need for global vaccine equity and coverage.

🔑 Key Findings

• To ensure global vaccine equity, vaccine targets were set by the COVID-19 Vaccines Global Access (COVAX) Facility and WHO.
• However, due to vaccine shortfalls, these targets were not achieved by the end of 2021.
• We aimed to quantify the global impact of the first year of COVID-19 vaccination programmes.
