Study on COVID-19 vaccination in the Americas Estudio de la vacunación contra el COVID-19 a nivel de América

Abstract

Introduction: one of our current expectations is to supply safe and effective vaccines to be administered to the population. The endpoint is achieving herd immunity through vaccination in order to break the chain of transmission. COVID 19 vaccination strategies expanding access to vaccine doses are necessary. Prioritization on the basis of ethical principles and risk criteria is required. Objective: to compare whether there are differences in COVID 19 vaccination rates per 100 people among the different countries of the Americas. Materials and methods: the vaccination database with the information collected to May 7 2021 was used. An analysis of variance test was applied using the SPSS v.25 statistical package. Results: the p-value obtained in the statistical analysis of variance test for the vaccination variable was 0.000, which is less than  α =0.05, therefore, the hypothesis (Ho) is rejected, which means, the analysis of variance test indicates there are significant differences in COVID-19 vaccination in the different countries of America. Conclusions: the outlook for COVID-19 vaccination in the Americas is quite worrying, as there are several countries with very low vaccination rates, maybe due to the fact vaccination is not a priority for all countries, especially for those with low population density, who are not experiencing high COVID 19 infection and death rates.
