The ENSEMBLE Study with Janssen’s Ad26.COV2.S Investigational Vaccine

The Ad26.COV2.S investigational vaccine is being developed to prevent or lessen the severity of COVID-19, the disease caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). The Ad26.COV2.S investigational vaccine includes bits of genetic material copied from the spikes of the SARS-CoV-2 virus. The goal is for the body to be immunized against COVID-19. The investigational vaccine does not contain the actual virus and cannot cause COVID-19. The ENSEMBLE study aims to test Janssen’s investigational vaccine in many different populations across the globe.

Visit ClinicalTrials.gov - NCT04505722 for additional details about the Janssen COVID-19 vaccine clinical study.
