[A survey of the immune effects and persistence of Chinese produced HB blood-origin vaccines].
A three-year systematic community survey was carried out in order to observe the immune effects and persistence of the 843-1 batch of HB vaccines produced by Beijing Biological Products Research Institute affiliated with the Ministry of Public Health. The results showed that the vaccination was safe and the reactions were slight. The antigenicity and short-term immune effects were good. After three years the positive rate and the P/N value of anti-HBs dropped considerably. This suggests that after 3 years of immunization, booster injection should be given to improve the immune level.
