乙型病毒性肝炎防控中乙肝疫苗接种的实施价值评估

Objective To explore the effectiveness of hepatitis B vaccination program during the prevention and control of hepatitis B virus. Methods A total of 100 people who completed three doses of hepatitis B vaccination from January 2020 to January 2021 were selected as the observation targets. Hepatitis B antibody titers were tested in the first, second and third years after vaccination. The titer of hepatitis B antibody in each group and the results of surface antibody conversion after the first vaccination of hepatitis B vaccine in the target population were recorded. Results In terms of hepatitis B antibody titer, the first year after vaccination was higher than the second and third years after vaccination in the target population (P＜0.05). The positive rate of hepatitis B surface antibody in the 100 target population in the first year after vaccination was higher than that in the second and third years after vaccination (P＜0.05). The positive rate of hepatitis B surface antibody was the highest in the target population after 24 weeks of hepatitis B vaccination (P＜0.05). Conclusion In the process of prevention and control of hepatitis B virus, hepatitis B vaccination is of great value in preventing the occurrence of hepatitis B and maintaining people’ s health.
