Dr. Men added that all tested vaccines of Nano Covax are quite safe and the vaccine administration ensured the correct procedures. The volunteers are now under health supervision at home.

Nanocovax, produced by the Nanogen Pharmaceutical Biotechnology JSC, was Vietnam's first coronavirus vaccine to enter human trials. Data relating to the vaccine trials are being processed to be sent to the Ministry of Health.

The second phase of the trials could commence immediately after Vietnam’s traditional Tet holiday in mid-February with 560 volunteers.

Sixty volunteers participated in the first phase in which they were split into three groups to be administer 25 mcg, 50 mcg and 75 mcg doses.

Currently, the Vietnam Military Medical University continues to recruit volunteers to participate in the second phase of clinical trial with a number of about 400-600 people to speed up the Covid-19 vaccine trial.

Volunteers participating in the second phase will be between 18 and 50 years old, or even from 12 to 75 years old.

Vietnam has three other vaccines under development by the Institute of Vaccines and Medical Biologicals, the Vaccine and Biological Production Company No. 1 and the Center for Research and Production of Vaccines and Biologicals.

The country has had 1,540 Covid-19 cases so far and 35 deaths. No community transmission has been recorded for over a month.
