Worldwide, up to 80% of liver cancer and hepatitis B virus infection in China, 71 percent of liver cancer by the hepatitis B evolved. Professor Zhang Meihui-based research, the World Health Organization (WHO) that hepatitis B vaccine is the only vaccine that can prevent primary liver cancer and hepatitis B vaccine to prevent hepatitis B is most effective, safe and economical method.
Hepatitis B vaccine in the prevention of mother to child transmission, Professor Zhang Meihui: with HBsAg positive is the highest risk mothers and their infants is most difficult to prevent the success rate in the small-scale clinical trials in the past when everyone can reach more than 90% of the benefits of prevention, but wait until the comprehensive implementation of his achievements did not like the small-scale so well, generally statistics seem, the whole look something about Eighty - five, then the HBsAg-negative mother and negative mother gives birth to a child, he is very good, small-scale study looks close to 100% can be prevented success, the entire large-scale look close to 100 percent, but they really produce the antibody status of not so high, means they are probably there may be almost about 5% of the children does not really produce a good antibody response.
Strengthening the crowd outside the neonatal hepatitis B vaccination
In 1992, China's Ministry of Health hepatitis B vaccine into children's immunization management, and promulgated the "National Hepatitis B vaccine immunization plan"; 2002, the State Council approved the hepatitis B vaccine into children's immunization of children in large cities since the hepatitis B surface antigen (HBsAg) carrier rate is significantly reduced. HBsAg carriers to reduce the number of 20 million. However, the whole of hepatitis B surface antigen carrier rate has not decreased significantly, particularly relative to the World Health Organization on the global hepatitis B control goal is still a considerable gap. Ministry of Health in 2005 hepatitis B as AIDS, tuberculosis, schistosomiasis focus on control of infectious diseases. Proposed on the basis of further improve neonatal immunization in people that are outside the neonatal hepatitis B vaccination strategies.
Scientific vaccination, active prevention
According to the experts, the hepatitis B vaccine is usually the method of the three June injected neonatal requirements inoculated 5-10μg dose of hepatitis B vaccine, adult leakage kinds of the kinds of persons should receive 20μg dose of hepatitis B vaccine within 24 hours after birth. The protection of the hepatitis B vaccine produced antibody levels are closely related, related to the level of antibody levels and hepatitis B vaccine contains the antigen content. At the same time, high-dose hepatitis B vaccine immune high success rate.
"Some people unfortunately because there is no hepatitis B vaccination suffering from hepatitis B, the deterioration of liver cirrhosis and liver cancer in the prime of life, a great pity." Huashan Hospital of Infectious Diseases, deputy director, said Professor Zhang Wenhong. Professor Zhang cited one of their own personal experiences of the cases: a 42-year-old male patient with chronic hepatitis B patients, 2000 patients with liver cirrhosis, was diagnosed with liver cirrhosis complicated with multiple liver cancer in the end of 2005, to rely on medication control of the disease, the life of the dying and the expensive medical costs for themselves and their families have brought great pain. Each person spends a great price for their disease after treatment, it is better to actively take preventive measures should be a clear understanding of their health status, hepatitis B antibody should be immediately vaccinated for prevention, "Professor Zhang said.
Chinese neonatal injection of 5μg dose hepatitis B vaccine, Professor Zhang said: "among children five micrograms and 10 micrograms difference, and now several studies, five micrograms of children three years old when detecting antibodies, and quite a few children have been detected not out, in this case we recognize the importance of ten micrograms Beijing's own money, with ten micrograms Zhejiang government to subsidize the Zhejiang government in August this year, positive mothers and newborns All inoculated with 10 micrograms, 10 micrograms is a trend. "
The participating experts, Hepatitis B is a contagious virus, daily life a little bit of skin damage likely to be infected with hepatitis B Such diseases insidious onset, it is difficult to detect, once suffering, it is difficult to cure, give patients the enormous economic burden and psychological burden, invisible killer of human health.
The data shows that China is the hepatitis B large country, about 57.6 percent of the population in the past or present are being infected with HBV. There are 120 million people carry chronic hepatitis B virus, chronic hepatitis B patients about 30 million people, we can say that the prevalence of hepatitis B can not be ignored.
In order to prevent hepatitis B and hepatitis-induced cirrhosis and liver cancer, from the outset to build a life "fence," and refused the hepatitis B viruses. Hepatitis B vaccine on the protection of mother to child transmission rate of 87.8% can protect more than 95 percent of the crowd from the threat of hepatitis B virus, and also to reduce the 85% -90% with hepatitis B virus-related mortality. For the large hepatitis B treatment costs and physical pain, hepatitis B vaccine is the most economic security, health investment, and quite effective.
