Study Summary

This study will be a phase-1, open-label, placebo-controlled, evaluation of two-dosages of a live, recombinant Newcastle disease virus expressing the spike protein of SARS-CoV-2 (NDV-HXP-S), an investigational product for IN, IM, or a combined IN+IM vaccination in healthy adults previously immunized against COVID-19. The IN and IM live virus vaccinations will be identical in composition and only differ in route of administration.

Primary Outcome

The safety and tolerability profile assessed by the number of local and systemic reactions.
