Based on the evaluation of these first three volunteers in the 72 hours following vaccination, the researchers will determine the correct dosage for the remainder of the total 60 participants. Participants will be closely monitored for 56 days and periodic follow-up evaluations will continue for six months from the first injection.

Nanocovax vaccine produced by Nanogen Company has been transported to Hanoi and is ready for this trial injection. The company has signed to buy insurance for volunteers.

Nanocovax jointly developed by Nanogen and the Military Medical Academy is Vietnam's first COVID-19 vaccine in a clinical trial in humans.
