Study Summary

This is Phase 1 study is to assess tolerability and immunogenicity of three dose levels of the investigational HDT-301 vaccine administered intramuscularly (IM), both in immunization-naïve participants and as a booster for those participants who previously received a SARS-CoV-2 vaccine. Safety and tolerability will be the primary endpoint assessed by incidence of adverse events at each dose through 12 months after completion of the vaccination regimen (either one dose, or two doses provided 56 days apart). Immunogenicity evaluations will be conducted for pre-specified timepoints as secondary and exploratory endpoints.

Primary Outcome

Frequency and grade of solicited local and systemic AEs during a 14 day follow-up period after each vaccination (i.e., the day of vaccination and 14 subsequent days).
