Comparing the Safety and Efficacy of Homologous and Heterologous COVID-19 Prime-boost Vaccination in Bahrain

Royal College of Surgeons in Ireland - Medical University of Bahrain·observational·Posted Aug 6, 2021·Updated Oct 26, 2021

In Brief

An observational study evaluating BBIBP-CorV and BNT162b2 for SARS-CoV 2 Infection and Covid19. Completed, enrolled 305 participants across 1 site.

Detailed Summary

Coronavirus disease 2019 (COVID-19) is potentially a deadly disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that targets the lung mainly, resulting in respiratory tract infections in humans. It has developed into a pandemic with serious global public health problems. Recent research has shown that the new SARS-CoV-2 variants reduces the efficacy of the vaccinations and are predominantly more transmissible or infective. A few countries namely Bahrain, United Arab Emirates, and Turkey have recently started introducing a booster dose following primary two doses of the COVID-19 immunization series. This study aims to identify which booster dose is more effective; taking a booster dose from the same vaccine initially taken or a booster dose from a different vaccine than initially taken.
