ABSTRACT
Background:
COVID-19 vaccination is currently the most effective tool to contain the spread of the pandemic and drastically reduce the number of hospitalizations and deaths. Despite the efficacy demonstrated in clinical trials, ecological studies, and real-world data, two years after the beginning of the vaccination campaign in many countries adherence is low, sometimes with coverage rates < 50%. The aim of the study is to explore the association between socioeconomic factors and COVID-19 vaccination coverage worldwide.
Methods:
High income countries with a population of more than 350,000, were included, for a total of 49 countries. Vaccination coverage (single dose and complete cycle at September 2021, and booster at November 2022) was extracted from OurWordinData and WHO database. From WorldBank website we obtained 12 indicators related to education, economic development, and health governance. To evaluate the associations between these indicator and Covid-19 vaccination coverage, we used Spearmans rank correlation coefficient with 95% bootstrapping confidence interval. P values
