Mortalidad por COVID-19 durante el plan de vacunación contra el virus SARS-CoV2 en Cali, Colombia

Abstract

El comportamiento de la pandemia de COVID-19 durante los tres picos registrados en Cali ha sido heterogéneo y la severidad de los contagios y decesos ha variado durante el tiempo. Cali con 2.2 millones de habitantes es la tercera ciudad mas poblada de Colombia, registra a la fecha (21-11-21) 285 mil casos confirmados y 7,474 muertes por la infección. El plan de vacunación contra el SARS-CoV2 iniciado en febrero de 2021, ha inmunizado en Cali 1.54 millones de personas.
 Al igual que en el resto del país, el desarrollo del plan de vacunación en Cali coincidió con el tercer pico de la pandemia, el más prolongado y de mayor mortalidad; así, como con múltiples movilizaciones sociales de cientos de manifestantes agolpados en las calles entre mayo y junio del 2021, en protesta a una reforma tributaria impopular promulgada por el gobierno nacional. En Cali el plan de vacunación también se afectó por falta de acceso a servicios de salud y puntos de vacunación por bloqueos registrados en diferentes territorios de la ciudad. Al final del tercer pico, el país afrontó dificultades para continuar con el plan de vacunación por barreras al acceso de biológicos en el mercado internacional.

COVID-19 mortality in two waves of the pandemic in Cali, Colombia, before and during vaccination roll-out

“…Deaths averted were calculated with the method described by Machado used in the MSPS Colombia study ( 9 ), which is based on the effectiveness of vaccines in preventing negative health outcomes, population coverage, and the change in frequency of these outcomes after applying the vaccination intervention ( 13 ). For this calculation, an estimated 81% overall effectiveness ( VE j ) of vaccines to prevent death ( 14 ) was used in the following equation:…”

Navigating the waves in Colombia: a cohort study of inpatient care during four COVID-19 waves

“…The COVID-19 immunization campaign in Colombia started in February 2021 and was carried out in stages, giving front-line healthcare providers and the elderly priority. 7 , 8 All age groups began receiving vaccinations in July 2021, and by February 2022, more than 60 % of the Cali and the Colombian population had received the recommended vaccination scheme (two doses of any vaccine or one Ad26.COV2.S). 7 , 8 Despite this, there is limited data on the clinical traits and prognoses of COVID-19 patients admitted to hospitals in Colombia during the several pandemic waves, both before and after immunization.…”

Assessment of these traits is essential to determine if public health initiatives like immunization and modifications to clinical treatment practices were effective.…”
