Vietnam starts second phase of human trial of Nano Covax

Nano Covax vaccine is developed and manufactured by HCM City-based Nanogen Pharmaceutical Biotechnology JSC. Before conducting clinical trials, the first Vietnam-made COVID-19 vaccine met all clinical criteria and was strictly checked by relevant agencies.  

The first phase of the human trials of the first Vietnam-made COVID-19 vaccine was conducted last year at the Military Medical University in Hanoi. The vaccine was highly evaluated for its safety and efficiency by the Health Ministry and eligible for the second phase.
