About this trial
The study aims to investigate the safety and immunogenicity of one dose vs two doses of a T-cell priming next-generation vaccine against Coronavirus disease.

Treatment groups
Trial outcomes
Primary outcomes
To assess the safety, tolerability and reactogenicity of the vaccine
Occurrence of solicited local reactogenicity signs and symptoms up to 7 days after each injection. Occurrence of solicited systemic reactogenicity signs and symptoms up to 14 days after each injection. Occurrence of unsolicited adverse events, serious adverse events (SAEs), and adverse events of special interest (AESI) up to 6 months following first vaccination or End Of Study (EOS), whichever is later.
Secondary outcomes
Assess the cellular immunogenicity of the vaccine candidate
Proportion of participants with T cells specific to PepGNP-COVID19 vaccine, and Proportion of subjects with activated cellular immunity cells via assessment of peptide-specific T cell response performed by cytometry, using dextramer staining and, by measuring activation markers upon stimulation with peptides
Assess the humoral immunogenicity of the vaccine candidate
For individuals seronegative at enrolment - Proportion of participants becoming seropositive (antibodies against SARS-CoV-2 as determined by Enzyme-linked Immunosorbent Assay (ELISA)), and For individuals seropositive at enrolment - Fold change in anti-SARS-CoV-2 antibodies as determined by Enzyme-linked Immunosorbent Assay (ELISA)
