Whole-Virion Inactivated SARS-CoV-2 Vaccine (BBV152) for COVID-19 in Healthy Volunteers (BBV152)

Study Description

This is an interventional study (clinic trial). Phase 2 is Randomized, Double-blind, Multicenter Study to Evaluate the Safety, Reactogenicity, Tolerability, and Immunogenicity of BBV152 in Healthy Volunteers. The clinic trial of phase 1 and 2 were conducted in India. The age is between ≥12 to ≤ 65 years.

Study Design

- Phase 1

1) Experiment: BBV152A or BBV152B or BBV152C. 0.5 ml of the vaccine will be administered intramuscularly twice at Day 0 and Day 14.

2) Control: Placebo: 0.5 ml of the Placebo will be administered intramuscularly twice at Day 0 and Day 14.

-Phase 2

1) Experiment: BBV152A or BBV152B. 0.5 ml of the vaccine will be administered intramuscularly twice at Day 0 and Day 28. 

Arms and Interventions

The outcome measurements for the Phase 1 and Phase 2 clinical trials of the **BBV152 (Covaxin)** vaccine evaluate patient safety and immune response across two distinct phases.

**Primary Outcome Measurements:**
- **Phase 1:** Occurrence of adverse events and serious adverse events (evaluating safety).
- **Phase 2:** Evaluation of neutralizing antibody titers pre- and post-vaccination (evaluating immune response).

**Secondary Outcome Measurements:**
- **Phase 1:** Evaluation of neutralizing antibody titers pre- and post-vaccination.
- **Phase 2:** Occurrence of adverse events and serious adverse events.
