About 80 volunteers are expected to receive the first shot of Covivac vaccine on August 18. Thai Binh province is the only locality nationwide selected for the second phase trials.

Covivac has been developed and produced by the Institute of Vaccines and Medical Biologicals. It is the second homegrown vaccine approved by the Ministry of Health for clinical trials, after Nanocovax.

The vaccine has been given to 100 volunteers at Hanoi Medical University during the first phase of human trials.

In the second phase, 375 volunteers, aged over 18, have been chosen and classified into three groups for the 3mcg and 6 mcg dosages and a dose of AstraZeneca vaccine.
