This is a Phase 1a, single-country, single-centre, single-blinded, COV2 vaccine formulation randomized trial designed to investigate and compare the safety and immunogenicity of two COV2 vaccine formulations. COV2 is a nasal, investigational vaccine against COVID-19, based on a serotype 5 adenoviral vector producing modified SARS-CoV-2 spike protein. Participants will receive one of the two COV2 formulations in two doses on Day 0 and Day 28. This trial consists of two parts; Part 1 is a vaccination phase assessing safety and immunogenicity and Part 2 is a long-term immunogenicity follow-up assessing persistence of immune response.
