The Health Ministry is holding negotiations with vaccine manufacturers and suppliers to secure vaccines for children of the age group.
Since the emergence of COVID-19, Vietnam has taken the initiative in seeking different sources of vaccines, he added.
Tuyen affirmed that the country now has sufficient COVID-19 vaccine to inoculate people of age 18 and above and children aged 12-17, and booster shots for adults.
A report of the national vaccination programme shows that about 97 percent of people aged 18 and above nationwide have received their first jab and 70 percent fully vaccinated.
In addition, about 5 million children aged 12 to 17 have received COVID-19 shots.
As of December 7, Vietnam had administered more than 128.67 million doses of COVID-19 vaccine. Over 55.01 million people have received two shots.
