Screening for volunteers participating in registration for the second test of the Nano Covax vaccine

3 groups of 10 volunteers will be given 3 doses of 25 micrograms, 50 micrograms, or 75 micrograms, and 5 volunteers will be given placebo, an inert substance with no therapeutic value.

The volunteers for phase 2 are 18 to 60 years old, and some have minor background illnesses.

Dr. Do Quyet, Director of Vietnam’s Military Medical Academy, said the results will be reported in May. In phase 3, volunteers will be given only 1 dose.
