Professor, Dr. Dang Duc Anh, Director of the National Institute of Hygiene and Epidemiology (NIHE), Covivac clinical trial researcher, said the screening and first dose of vaccine will be carried out from January 21.

Phase two begins in July-August and ends in September, at Vu Thu District Medical Center, Thai Binh, expected to have over 420 people.

Dr. Duong Huu Thai, Director of the Institute of Vaccines and Medical Biologicals (IVAC), said that vaccine testing is fast but must be optimal.

Covivac is Vietnam’s second Covid-19 vaccine approved for clinical trials, developed by IVAC and produced using chicken egg embryo technology.

On the morning of January 21, IVAC coordinated with NIHE and Hanoi Medical University to recruit volunteers for phase one clinical trial.

According to Dr. Thai, the injection doses are less than the Nanocovax vaccine due to different production and immunogenicity principles. The two vaccines should not be based on the content.

A doctor advises a group of medical students registering for a vaccine clinical trial, on the morning of January 21.

Faced with concerns that the nCoV strain could make the vaccine no longer effective, Dr. Thai said that the virus mutation has not affected the S gene region selected as the vaccine antigen.

`I have confidence in the scientific and technological foundation and achievements that have been achieved. I believe that this is a vaccine with potential and hope in the future,` Dr. Thai said.
