Lessons from COVID'S Vaccination: External-Internal Frictions and Efficiency

Area of Science:

• Epidemiology
• Public Health
• Health Economics

Background:

• The emergence of new COVID-19 variants poses a significant global health threat.
• Understanding the socio-economic drivers of variant emergence and vaccination progress is crucial for pandemic control.

Purpose of the Study:

• To investigate economic and social determinants influencing the emergence of new COVID-19 variants.
• To identify factors affecting vaccination advances across 108 countries between March 2020 and March 2022.

Main Methods:

• Econometric analysis of quarterly data from 108 countries.
• Variables examined include vaccination rates, education levels, urbanization, city crowding, health crisis preparedness, and economic complexity.

Main Results:

• Increased full vaccination coverage and higher education levels were associated with a decreased probability of new COVID-19 variant emergence.
• Higher population density in cities and greater urbanization increased the likelihood of variant emergence.
• Vaccination percentages were positively correlated with health crisis preparedness, education, and economic complexity index.
• Higher rural population percentages negatively impacted vaccination rates due to logistical challenges.

Conclusions:

• Socio-economic factors significantly influence both COVID-19 variant emergence and vaccination campaign success.
• Investing in education, health infrastructure, and economic complexity can bolster vaccination efforts and mitigate variant emergence.
• Urbanization and population density present challenges that require targeted strategies for pandemic management.
