THE country’s domestic Covivac coronavirus vaccine is being administered to volunteers from communes in the northern province Thai Binh as part of its ongoing phase two clinical trials.
Thai Bình is the only locality nationwide selected for the trial of the vaccine developed by the Institute of Vaccines and Biological Medical based in Nha Trang, Khanh Hoa province.
About 80 volunteers in Minh Lang, Viet Hung and Bach Thuan communes in Vu Thu District are expected to receive the first shot of the two-dose regimen.
The selected volunteers are above the age of 18 and have no serious health issue or chronic disease. Female volunteers of child-bearing age must agree to use a birth control method for at least 28 days after the second jab.
Covivac is the second homegrown vaccine approved by the Ministry of Health for clinical trials, after Nano Covax by Ho Chi Minh City-based pharmaceutical company Nanogen, which is currently in phase three trials.
Covivac vaccines were given to 100 volunteers during the first phase of clinical trials.
For the second phase, a total of 375 volunteers aged over 18 have been classified into three age groups – 18-39, 40-59 and above 60.
Each group of 125 people will be administered a 3mcg or 6mcg dosage of the AstraZeneca Covid-19 vaccine as a control.
Blood samples collected from the second phase will be sent to Canada for an independent evaluation. — Vietnam News/ANN
