HCMC – Reporting good news over the Covid-19 vaccine made in Vietnam, the Ministry of Health on January 14 announced that the Nanocovid vaccine had produced a strong immune response, far beyond expectations.

The efficacy has surpassed expectations, said Ho Anh Son, deputy head of the Institute of Biomedicine and Pharmacy under the Vietnam Military Medical Academy.

Son told Tuoi Tre Online that after being injected the first shot of the Nanocovid vaccine made by Nanogen 28 days ago, those vaccinated were monitored for three days and for a few days after that via the telephone.

The health of the three volunteers who received the first injection was stable and they received a second shot of the vaccine with a dosage of 25 micrograms on January 14.

After the three volunteers received the two injections in the first phase of the human trials of the vaccine, the vaccine proved to be safe and was reported to elicit high antibody levels to the coronavirus, he said.

The ministry plans to start the second phase of the human trial after the Lunar New Year holiday.

The vaccine researchers are calling on volunteers to sign up for the second phase scheduled for February as the second phase will need some 560 participants.

Until date, 40 volunteers have been injected with the Covid-19 vaccine with the three dosages of 25, 50 and 75 micrograms. Their health is stable.
