Vietnam has completed the second phase of testing of the domestic Nano Covax

According to the research team, the results of the second phase of the Nano-Covax human trial show that the COVID-19 vaccine grown in China is safe. Navo Covax was developed by Nanogen Pharmaceutical Biotechnology JSC. The vaccination was conducted on 560 volunteers. Divided into four groups: 80 people received placebo, and the other three groups received 25μg, 50μg and 75μg doses. However, only 554 people received repeated injections, and 6 of them dropped out of the study. All vaccinated volunteers have developed different levels of antibodies against COVID-19. With regard to the rate of antibody neutralization of the virus, people administered at a dose of 25 µg had the highest incidence, exceeding 90% at 14 days after the second injection and 42 days after the first injection. He is expected to report to the Research Ethics Committee of the Ministry of Health on Tuesday, and may propose a third phase of human research plans on May 5. A series of human studies is expected to involve 10,000 to 15,000 people in countries with severe coronavirus outbreaks in Vietnam and Asia. Volunteers receive 25 µg, which is the only dose at this stage. Everyone received two injections.and people should have the second Nano Covax injection 28 days after the first injection. The Navo Covax vaccine began human trials on December 17 last year and completed the second phase. He is ready to enter the third stage, the final stage of the test. Nano Covax’s Phase 1 study showed that the vaccine is safe, and the vaccinated volunteers have antibodies against the British variant (B117). Based on the results of the first and second phases, experts are optimistic that the third phase of the study will be completed by the end of the third quarter. Compared with the previous plan, this will shorten the investigation time by three months. So far In this case, 209,600 Vietnamese have been vaccinated against COVID-19… 209,632 people were vaccinated at 4:00 pm on Sunday, including front-line doctors, medical staff, sample collectors, contact markers, and Member of the COVID-19 and COVID Prevention and Control Steering Committee.
