Brief Summary:
This phase I trial evaluates the side effects and best dose of COH04S1, a synthetic modified vaccinia Ankara (MVA)-based SARS-CoV-2 vaccine, for the prevention of COVID-19 infection. COVID-19 infection is caused by the SARS-CoV-2 virus. SARS-CoV-2 has demonstrated the capability to spread rapidly, leading to significant impacts on healthcare systems and causing societal disruption. COH04S1 was created by placing small pieces of SARS-CoV-2 DNA (the chemical form of genes) into synthetic MVA, which may be able to induce immunity (the ability to recognize and fight against an infection) to SARS-CoV-2. The purpose of this study is to determine the safety and the optimal dose of the COH04S1 vaccine.
