1a National Institutes for Food and Drug Control No.2 ; Tiantan Xili ; Beijing , China.
Hepatitis B vaccination in China has significantly reduced infections in young children. Continued efforts are needed to optimize strategies and improve public awareness to combat the remaining challenges of Hepatitis B virus (HBV) infection.
Area of Science:
- Public Health
- Vaccinology
- Epidemiology
Background:
- Hepatitis B (HB) poses a significant public health challenge in China.
- Hepatitis B virus (HBV) vaccination is a highly cost-effective prevention method.
- Since 1992, China's HBV vaccination program for newborns has led to reduced infection rates.
Purpose of the Study:
- To assess the impact of HBV vaccination in China.
- To identify remaining challenges in HBV infection prevention and control.
- To recommend optimized strategies for HBV vaccine application.
Main Methods:
- Analysis of HBV infection prevalence data.
- Evaluation of the national HBV vaccination program's effectiveness.
- Review of public knowledge and awareness regarding HBV vaccination.
Main Results:
- Prevalence of hepatitis B surface antigen (HBsAg) in children under 5 has decreased to 1.0%.
- Significant HBV infection sources remain, with 93 million carriers and chronic patients.
- A knowledge gap exists regarding the impact of HBV vaccination among the general public.
Conclusions:
- While childhood HBV vaccination has been successful, challenges persist.
- Optimizing immunization strategies based on HBV prevalence is crucial.
- Enhancing public knowledge about HBV vaccination is essential to ensure vaccine efficacy and control spread.
