Effects of coronavirus disease vaccine administration on SARS-COV-2 new death rate in Colombia

Efecto de la aplicación de vacunas contra COVID-19 sobre la nueva incidencia de los índices de mortalidad por SARS-COV-2 en Colombia

Introduction: the rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) worldwide and coronavirus disease 2019 (COVID-19), has caused a global pandemic with devastating social and economic consequences. Objective: to show if there is a correlation between COVID-19 related deaths and vaccination against SARS-COV-2 in the period from February 17 to May 27 2021.  Methodology: an experimental research design was used. Data was obtained from the Ministry of Health and Social Protection website, based on the COVID-19 related deaths and vaccination daily reports, for said period. Results: the p-value obtained in the tests for COVID-19 infection and vaccination against SARS-COV-2 variables is 0.000, which is less than α =0.01, thus, the hypothesis (Ha) is accepted, which means the Pearson correlation test indicates there is a relation between COVID-19 death rate and SARS-COV-2 vaccination in Colombia. Conclusion: since vaccination against COVID-19 begun in mid-February 2021 in Colombia, no decrease in the number of deaths due to COVID-19 has been evidenced. Although there has been an increase in the number of vaccinated persons from February to May 2021, there was no decrease in the death rate in the same period.  Considering the above, we can suggest that vaccination in 2021 in Colombia has not yet become a fully effective measure.
