“China initiated the National Expanded Program on Immunization (EPI) in 1978. The targeted children were vaccinated with Bacillus Calmette-Guérin (BCG) vaccine, oral polio vaccine (OPV), measles vaccine (MV) and diphtheria, tetanus and pertussis (DTP) vaccine according to the immunization schedule recommended by the World Health Organization (WHO). The coverage of children with these three vaccines reached the goal of 85% at provincial, county, and township

level in 1988, 1990, and 1995, respectively. Cases of tuberculosis, polio, measles, pertussis, diphtheria, and tetanus decreased by about 300 million, and an estimated 4 million lives were saved by the Pfizer Licensed Compound Library high throughput program over the 30 years following its launch [1]. The Western Pacific Regional Office (WPRO) of the WHO, where China is located, certified China to be Polio-free in 2000. There have been no reported cases of polio due to wild poliovirus in China since 1994

[2]. Comparing data collected prior to the implementation of EPI, the reported national measles morbidity www.selleckchem.com/products/Adriamycin.html and mortality rates have declined by more than 95% in 1990. The reported incidence of measles dropped to a historically low level of 5/100,000/year in 1995.The reported incidence of diphtheria decreased from 10 to 20/100,000/year in the 1950s to <0.01/100,000/year in the 1990s, while pertussis decreased from 100 to 200/100,000/year during the 1960–1970s to 0.37/100,000/year in 2004. The annual number of reported cases of diphtheria and pertussis ranged from 0 to 11 and 3000–6000, respectively, during 2003–2008

[1]. China integrated hepatitis B Isotretinoin vaccine (HBV) into the national EPI program in 2002. Following the implementation of the hepatitis B immunization program, the hepatitis B surface antigen (HBsAg) seroprevalence rate for the population aged 1–59 years declined from 9.8% in 1992 to 7.2% in 2006, and for children age 1–4 years it was 0.96% [3]. Overall, implementation of the national EPI has played an important role in the protection of the population’s health, contributing to increased average life expectancy and to the creation of large economic and social benefits. In 2007, China integrated into the national immunization program vaccines against meningococcal meningitis, Japanese encephalitis, hepatitis A, rubella and mumps. These vaccines will play an important role in advancing the control of these vaccine-preventable diseases. China’s Experts Advisory Committee on Immunization Program (EACIP) was established in 1982 and has evolved continually since then throughout the implementation of EPI. It has become a key technical advisory body and plays a vital role in formulating national policy and providing technical guidance to EPI and other immunization issues.
