In Brief

A Phase 2 clinical trial evaluating Recombinant NDV Vectored Vaccine for SARS-CoV-2 and Placebo for SARS CoV 2 Infection. Completed, enrolled 158 participants across 4 sites.

Detailed Summary

This is a Phase II study with single-blinded safety phase followed by double-blinded randomization, placebo-controlled, of administration of a single dose by two different administration routes (intramuscular route or intranasal route), to evaluate immunogenicity and safety of the recombinant SARS-CoV-2 vaccine (AVX/COVID-12 vaccine) based a live Newcastle disease viral vector (rNDV) in 396 healthy subjects with evidence of prior immunity to SARS-CoV-2, followed by a booster response assessment with an intramuscular dose of COVID-19 vaccine (ChAdOx-1 -S\[recombinant\]) in subjects originally randomized to the placebo arm at several research sites in Mexico City.
