Abstract:
On 293 healthy children of 2-4 years old of age in the Commune Song Ho, Thuan Thanh District, Bac Ninh Province, of them 101 children were vaccinated with Vietnam produced vaccine and 102 with Biken vaccine. Results showed that Vietnam produced vaccine manifested an antibody response of 100% with Tb antibody valent (GMT) of 3.48. After 1 year of basal immunization, GMT decreased by 2.49 but it was still higher than 2.5 times of minimal value and after the 3rd injection of vaccines GMT increased by > 4.01 times higher than the basal immunization level. In comparing with Biken vaccine, the Vietnam produced vaccine has a GMT antibody response rate and a long duration of life of antibody with high level comparable to the Japan produced vaccine
