COVID-19 and older adults: spatiotemporal comparison between mortality and vaccination in the province of Buenos Aires, Argentina

Abstract

The aim of this study was to analyze the spatiotemporal variations of COVID-19 mortality and vaccination against COVID-19 in older adults. We used data from deaths due to COVID-19 and persons aged 70 years and older immunized with the first dose of vaccines against this disease, from districts of the province of Buenos Aires, between December 29, 2020, and June 30, 2021. Spatiotemporal scanning techniques were used to detect clusters. The parties of Greater Buenos Aires that had the highest vaccination rate with the first dose of the Sputnik V vaccine in population aged 70 years and older, between mid-March and early April 2021, also registered a decrease in mortality in this population, between the end of April and the end of June 2021. This study showed some signs of the positive impact associated with the application of the first dose of Sputnik V vaccine in Greater Buenos Aires.
