These results suggest that the immune effects of the four hepatitis B vaccine types were good, and that they could provide good protection for the population. 872 adults Articaine HCl completed the immunization routine and their blood Rabbit polyclonal to annexinA5 serum was tested after completing the three vaccinations. Among these subjects, 771 were males whose average age was 32.59 years (95% confidence interval (CI): 32.01?33.17) and whose median age was 32.33 years. There were 1 101 female subjects whose average age was 32.42 years (95% CI: 31.94?32.91) and Articaine HCl whose median age was 31.96 years. There were no statistically significant differences in age or gender among the four groups (Table ?(Table1;1; value value0.7720.539* 0.0200.0230.073 Open in a separate window value0.6650.1800.0000.0010.003 Open in a separate window was 1 670) 4.?Conversation Currently, hepatitis B vaccine is widely used to prevent HBV contamination in China and abroad. The Advisory Committee on Immunization Practices (ACIP) proposed that non-immune adults should be encouraged to be immunized with the hepatitis B vaccine (Goldstein et al., 2005). An American statement in 2007 showed that the highest proportion of new hepatitis B infections occurs in the 25 to 44 years old age group (Daniels et al., 2009). Vaccination for high-risk adults experienced already begun in USA in 1998 (Mast et al., 1998), and in 2006, adult hepatitis B vaccination was brought into the system of community main health care and rehabilitation clinics (Mast et al., 2006). There Articaine HCl were also immunization programs for high-risk adults in Britain and Italy (Bonanni, 1995; Zuckerman and Langer, 2005). The usual adult hepatitis B vaccine dose in China is usually 10 g. You will find three main types of hepatitis B vaccine in China: one is made by recombinant deoxyribonucleic acid (DNA) techniques in yeast, one is made by recombinant DNA techniques in CHO cells, and one is a recombinant hepatitis B vaccine (yeast by the Beijing Tiantan Organization. The seroconversion rate was 90.69%. They selected 873 HBsAg unfavorable subjects. Another study of 321 subjects, using 10 g hepatitis B vaccine produced by the North China Pharmaceutical GeneTech Biotechnology Pharmaceutical Co., Ltd.) (CHO), had an 88.8% seroconversion rate. Factors such as smoking, drinking, and obesity were reportedly associated with immune failure, in addition to a strenuous job, stressful lifestyle, and mental pressure, which may overload the body and lead to a decline in immune function and thereby impact the seroconversion rate. The immune effect of the Dalian High-Tech 10 g Hansenula hepatitis B vaccine was the best of the four types. Its seroconversion rate reached 95.05%, a rate significantly higher than those of the other three groups. This seroconversion rate was also comparable to that of the 20 g hepatitis B vaccine reported by Young et al. (2001). This similarity might be caused by the high purity of the Hansenula hepatitis B vaccine, which uses a chemosynthesis complete medium only, and not a selective medium, peptone or yeast powder. The seroconversion rates of the 10 g hepatitis B vaccine produced by the North Articaine HCl China Pharmaceutical Organization and GlaxoSmithKline were slightly higher than that of the 10 g hepatitis B vaccine previously reported by Young et al. (2001). Regarding the anti-HBs GMT, the immune effects for all the vaccines were good, except those of the Shenzhen Kangtai vaccine. These results suggest that the immune effects of the four hepatitis B vaccine types were good, and that they could provide good protection for the population. Considering the high anti-HBs seroconversion rate and GMT produced by the Dalian High-Tech vaccine, and considering that the persistence of immune Articaine HCl protection would be extended as a result of the high GMT peak value (Jilg et al., 1988; Trivello et al., 1995; Yuan et al., 2003), we recommend the Dalian High-Tech vaccine. An analysis of the hepatitis B vaccine immune effects in adults of different age groups was conducted. After dividing the subjects into five age groups, the.
