A representative of the Military Medical University said in this phase, the vaccine will be tested on around 13,000 volunteers aged between 18 and 74, in many localities nationwide.
The 3rd phase, also the final one, will evaluate the effectiveness of the vaccine and each volunteer may only receive one jab of 25 mcg.
Director of the university Prof. Dr. Do Quyet showed his confidence in the safety of Nano Covax vaccine, developed by Vietnamese Nanogen Pharmaceutical Biotechnology JSC, with the positive results obtained from the previous two trial phases.
Nano Covax vaccine started testing on humans on December 17 last year and has completed the second phase.
The first-phase trials showed the vaccine was safe and vaccinated volunteers had antibodies against the UK variant (B117).
The second-phase ones were conducted on 560 volunteers divided into four groups, with 80 people injected with a placebo and three other groups administered with 25mcg, 50mcg, and 75mcg doses. However, only 554 received second shots because six people withdrew from the trial.
All of the vaccinated volunteers have developed antibodies against the coronavirus at different levels.
