Clinical Trial Summary

The purpose of this study is to evaluate the effectiveness of the COVID-19 vaccine in hospital based HWs in Albania. This will answer critical questions about the real-world performance of COVID-19 vaccines in one of the key target groups for vaccination.


Clinical Trial Description

This protocol describes a prospective one-year cohort study of hospital-based health workers in Albania to evaluate the effectiveness of COVID-19 vaccine in preventing laboratory-confirmed SARS-CoV-2 infection and COVID -19 disease. The investigators will measure the effectiveness of COVID-19 vaccines against laboratory-confirmed SARS-CoV-2 infection in both symptomatic and asymptomatic hospital health workers. SARS-CoV-2 infection will be diagnosed using symptom questionnaires and PCR testing. Additionally, serology testing will be obtained over the course of one year, to identify asymptomatic infections. ;
