Around 1,618 infants or 45 percent were injected with the Korean-made vaccine Quinvaxem in the central highland town of Da Lat, according to Dr. Chu The Vinh, Head of Preventive Medicine Center in Da Lat Town in Lam Dong Province.
The figure shows a sharp fall in vaccinations in children compared to previous times when 90 percent were vaccinated, due to adverse information that worried parents.
The vaccine Quinvaxem had been earlier suspended due to post-vaccination reactions in children, but then again re-used after several months.
Dr. Vinh said six toddlers who were hospitalized after vaccination from November 14 -16 have been discharged from hospitals.
They were taken to Lam Dong General Hospital as they suffered side effects from the vaccine, such as fever and vomiting. One of them even turned blue and developed convulsion fits.
In addition, 20 others were also taken to health centers in districts and communes for post vaccination side effects.
