The development objective of the Additional Financing (AF) for El Salvador’s COVID-19 Emergency Response Project is to respond to and mitigate the threat posed by COVID-19 and strengthen the national system for public health preparedness. The Project is financing the purchase and deployment of COVID-19 vaccines as well as financing both the scale-up of initial project activities and the implementation of new activities designed to contribute to successful vaccine deployment. By August 2021, El Salvador became a leader within the larger Central American region as it boasted the highest percentage of people who are fully vaccinated (33.7% of the total population.) By August 2022, according to the World Bank COVID-19 Vaccine Deployment Tracker, El Salvador had fully vaccinated 67% of its total population.
