Análisis Estadístico del Registro Ecuatoriano de Vacunación COVID-19 del año 2021

Abstract

The statistical analysis of the Ecuadorian vaccination registry COVID-19 of the year 2021, aims to identify the impact of the percentage of vaccination in the administrative areas of planning of Ecuador in the availability of ICU beds for COVID-19 patients. The study was carried out in the statistical software R, in its integrated development environment R Studio using statistical techniques, such as statistical graphs, descriptive measures, and Pearson Chi-square test of independence. The registry is of 4,368,997 individuals of which 67% have the first dose and 33% have the complete vaccination schedule, 44.6% of the entire vaccinated population belong to the provinces of Pichincha and Guayas. Related to the vaccines, 48% of the population that has both doses was vaccinated with Pfizer, Sinovac with 35% and 17% for AstraZeneca. According to the choropleth map, the administrative area of planning 9 possesses the highest percentage of vaccinated people 20.27%, meanwhile zone 2 represents the lowest percentage of the vaccinated population, 4.22%; in the application of Chi-square test of independence it was identified that the variables age groups and vaccines were not independent of each other, in turn the variables applied dose and hospitalizations through statistical evidence showed that they were not independent of each other. According to regression analysis the forecasts made show that hospitalizations will increase, unlike the real data. It is concluded that there is a positive impact of mass immunization on the availability of ICU beds. It is recommended to apply new techniques and increase as far as possible the amount of data in future studies to improve the results.
