The shots were administeredon a 6:1 ratio, which meant six got the vaccine and one received placebo,according to Lt. Col. Chu Van Men, Director of the university’s Centre for Clinical Trials and Bioequivalence.
The volunteers will haveblood samples taken to test the generation of immunity by July 30, and dataabout the vaccine safety and immunity generation are set to be available bymid-September.
After the first 1,000volunteers, the trials of Nano Covax will continue on another 12,000 on a 2:1ratio, with two getting the vaccine and one the placebo.
The third-phase trials, usingonly the 25mcg doses, cover 13,000 volunteers aged between 18 and 75 nationwide.
Results of the first twostages show good immunity generation in all volunteers, Men noted.
Nano Covax has been developedby the Nanogen Pharmaceutical BiotechnologyJSC since May 2020. The first-phase trials began on December 18, 2020 while thesecond phase on February 26 this year, and the third on June 11.
