LatInamerican Vaccine Effectiveness Against Hospitalizations Due to Circulating COVID-19 VoC RWE Study

Overview

COVID-19 is the infectious disease caused by the novel coronavirus known as SARS-CoV-2, that appeared in 2019. The World Health Organisation (WHO) declared the novel coronavirus a pandemic on 11 March 2020. The evolution of the pandemic is varying across countries, affected in part by different containment strategies ranging from extreme lockdown to relative inaction. As a result, there are regional waves of the disease and pockets of vulnerable populations. Globally, governments have acknowledged that effective vaccines against COVID-19 are the only way to guarantee a safe and sustained exit strategy from repeated lockdowns. The objective of this study is to estimate the vaccine effectiveness against hospitalizations due to circulating COVID-19 VoC among subjects eligible for vaccination with the AstraZeneca or any other COVID-19 vaccine provided in their country as per national/regional immunization recommendations prior to hospital admission. The study design is an observational prospective active-surveillance hospital-based study, with a test-negative case-control design (TNCC) of hospitalized COVID-19 like cases undergoing testing for SARS-CoV-2

LatInamerican Vaccine Effectiveness against hospitalizations due to circulating COVID-19 VoC RWE study is an observational prospective active-surveillance hospital-based study, with a test-negative case-control design (TNCC) of hospitalized COVID-19 like cases undergoing testing for SARS-CoV-2 by RT-PCR or rapid antigen test with the participation of countries from six LatAm Marketing Companies (Argentina, Brazil, Colombia, Costa Rica, Mexico and Panama). This study will generate new information regarding vaccine effectiveness (VE) in the RW setting for populations where evidence is still unavailable
