Nano Covax vaccine researched and produced by NANOGEN Company is the first Covid-19 vaccine manufactured by Vietnam and tested on humans.
1. What is the Nano Covax vaccine?
Nano Covax vaccine/vaccine is a Covid-19 vaccine. This is Vietnam’s first Covid-19 vaccine, researched, developed and manufactured by Nanogen Pharmaceutical Biotechnology Joint Stock Company.
2. How effective is the Nano Covax vaccine?
The research team said that at stage 3a, the study showed that the Nano Covax vaccine met the requirements for immunogenicity and safety. After 14 days of injection of the second dose, the ability of this vaccine to neutralize live virus reaches 96.5%.
In stage 3a, the participants who volunteered to receive the Covid-19 Nano Covax vaccine were more diverse in age and gender, of which the youngest was 18 years old, and the highest was 81 years old. The proportion of the 18-45 year old group accounts for 60%, the 46-60 year old group is 22%, the over 60 year old group accounts for 17%. The group participating in this vaccine trial included people with a history of chronic heart disease, allergies, hypertension, cancer, obesity, etc. with 162 people.
Through research and testing in both phases 2 and 3a, the research team concluded that the average concentration of Anti-S-IgG antibodies of this vaccine reached 57.56 U/ml, after 42 days of vaccination increased and increased. 218.93 times. And the average seroconversion rate was 99.2%.
Some experts say that the Nano Covax vaccine has the same protective effect as many other Covid-19 vaccines in the world, including about 75% with the Delta variant. About the side effects after injection are mainly mild and moderate, such as pain at the injection site, fatigue, joint pain, nausea…
Regarding the safety of this vaccine, sharing in the People’s Electronic Army newspaper, the Political Commissar of the Military Medical Academy Major General, Assoc. No cases of anaphylaxis occurred.
Regarding the protective effect of the Nanocovax vaccine, Major Luong also said that comparing the ratio of IgG antibody levels of the group of recovered Covid-19 infected patients and the vaccinated group of volunteers showed that the Nanocovax vaccine was effective. protective results against Covid-19 and with the Delta variant, Alpha is also initially effective.
Currently, more than 14,000 volunteers who have been tested for the Nanocovax vaccine at all 3 stages are healthy, are being monitored and continue to be evaluated. There are 2 cases of grade 1 and grade 2 anaphylaxis who are now healthy.
3. Mechanism of action of vaccine Nanocovax
