Glycovax Pharma has developed a glycoconjugate vaccine candidate called Glycovax-002 to fight the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the origin of COVID-19. The aim of the study is to assess the safety, reactogenicity and immunogenicity of Glycovax-002 in humans. The study is a phase I, placebo-controlled, dose-escalation study conducted in 36 healthy females and males aged between 18 and 55 years old. The vaccine will be administered three times with a two-week time interval between each dose. Dose escalation is conducted in three steps. At each step, 9 participants receiving the vaccine will be randomized with 3 participants receiving placebo (normal saline). Progression to next step is conditional to a DSMB's approval.

To assess the overall safety and reactogenicity of the Glycovax-002 conjugated vaccine administered at three different doses in healthy adults.
Safety: * Incidence of Adverse Events (AEs) in all participants. * Occurrence of each solicited local and systemic AE, during each 7-day follow-up period after injection. * Occurrence of any AEs until 28 days after the last injection. * Occurrence of serious AEs until one year after the first injection. * Assessment of safety will involve blood tests for biochemistry, hematology, serum chemistry and immunogenicity, urine tests for urinalysis, and participant diaries. Reactogenicity: Reactogenicity will be assessed by the incidence of the following solicited reactions for the first 7 days after each administration: Local: * Swelling at injection site * Erythema at injection site * Pain at injection site General (systemic): * Fever * Fatigue * Chills * Diarrhea * Myalgia * Arthralgia * Headache * Nausea/Vomiting
Time frame: Day 0 - 360
To assess the immunogenicity induced by Glycovax-002 in healthy adults
Immunogenicity will be assessed prior to each dose of Glycovax-002 and then at 1 and 3 months after the last dose, i.e. at Days 0, 14, 28, 56 and 120, except otherwise stated. * Serum anti-TF IgG * Total serum IgG, IgA, and IgM * Cytokine (Th1 and Th2) concentration in serum, at baseline and six hours after the last Glycovax-002 administration on Day 28: * IFN-γ * TNF-α * IL-2 * IL-4 * IL-13 * CD4 and CD8 T-cell and B-cell counts and CD4/CD8 ratio.
Time frame: Day 0 - 120
To assess the virus-neutralizing antibody response induced by Glycovax-002 in healthy adults
SARS-CoV-2 virus-neutralising antibody levels in serum, on Days 0 and 56 only, by a pseudovirus neutralisation assay * based on the original Wuhan viral strain, and * based on the latest Variant of Concern available for testing at time of study initiation.
Time frame: Day 0 - 56
