Official results for the second phase are expected to be reported to the Ministry of Health on April 27. Upon completion of human trials, Nanocovax is expected to seek emergency approval for community distribution.

Researchers said they would use the result produced by the lowest 25 microgram dosage group as the proposed optimal dose for use in Nanocovax’s third phase of human trials, expected to start from May 5 to late June, involving over 1,000 volunteers.
In the third phase, 10,000-15,000 people, including volunteers in countries such as India, Hungary and Bangladesh, will join the trial.
In this phase, the Ethics Council in Biomedical Research will decide on whether to immediately administer this vaccine to Vietnamese people in high-risk groups such as anti-pandemic forces and employees at airports and flight attendants. The decision will be made on the results of the second phase clinical trials.
Nanocovax vaccine of Nanogen is Vietnam’s first Covid-19 vaccine in clinical trial. Trial of phase 1 took place from December 17, 2020 to February 7, 2021.
Vietnam expects to complete clinical trial of Nanocovax vaccine by the end of this year so that it can start large-scale production and widespread use by early 2022.
Vietnam is currently developing four domestic Covid-19 vaccines: Nanocovax by Nanogen, Covivac by the Institute of Vaccines and Medical Biologicals (IVAC), and two others by the Vaccine and Biological Production Company No. 1 (Vabiotech) and the Center for Research and Production of Vaccines and Biologicals.
