RESUMEN
Planned immunization program in Jiading District has experienced nearly 70 years，and basically established a relatively complete vaccination service system. Vaccination clinics have experienced four rounds of construction，which facilitates scientific，standardized，and informationized clinics. Moreover， it has trained a great deal of public health professionals in immunization program. Vaccines are able to be ordered and distributed uniformly，achieved with cold-chain equipment and real-time monitoring of temperature. Through a networking of vaccination information system， five-code linkage， which means vaccine traceability code， vaccine producing code，cold-chain equipment code，vaccinated child code，and vaccinating doctor code， has been achieved. Vaccines for expanded program immunization developed quickly， from 7 categories for preventing 8 diseases to 12 categories for preventing 13 diseases. In addition， number of self-funded vaccines are increasingly available. Currently， Jiading District is the first district implementing vaccination compensation insurance in Shanghai. Vaccine-preventable diseases are effectively controlled. However，challenges remain in the insufficient supply of self-funded vaccines and thorough elimination of measles.
RESUMEN
Objective To investigate the distribution of school students' HBsAg in Xianju county, and the effect of the Hepatitis B vaccine in terms of students' HBV infection after the implementation of planned immunization. Methods HBsAg was tested by ELISA, and then analyze the students' HBsAg carrier rate. Results The positive rate of students' HBsAg in Xianju county was 2.28%. There was no significant difference between boys and girls.The HBsAg-positive rate is highest in high school and secondary in junior school and lowest in primary school, there was significant difference in different grades (P<0.05). The HBsAg-positive rate was increased with increasing age. Conclusion Xianju county achieved remarkable results in the prevention of Hepatitis B in children and adolescents in recently 20 years. Hepatitis B vaccine immunization program is the main effective measures to prevent Hepatitis B infection in children.
RESUMEN
Objective To understand the changing trends of immune-related diseases.Disease patterns from both pre-and post-immunization plan and after the immunization program were described,in order to provide evidence for the formulation and revision of immunization program and policy,in Ningxia Hui Autonomous Region.Methods According to the time order descriptive method was used to analyze and compare the reported data on infectious diseases in Ningxia,between 1958 and 2014.Results From 1958 to 2014,both incidence and mortality of infectious diseases and four diseases related to the immunization programs,in Ningxia appeared significantly low.Since the implementation of the immunization plan,the incidence and mortality of the 4 diseases declined significantly,with the average annual total incidence as 176.12/100 000 before the immunization plan dropped to 2.56/100 000 when the expanded immunization plan was put into practice.The incidence also showed a downward trend.Among diseases that under the immunization program,the incidence of measles appeared the highest,followed by pertussis.However,none of the case on diphtheria or polio appeared which was caused by the wild strains,in 1983 and 1994.Conclusion After the implementation of the immunization plan,the immune-related diseases seemed to have been under well controlled.and with remarkable social benefit.Immunization programs appeared the most effective measures to control and eliminate the acute infectious diseases in the region.

RESUMEN
Objective To explore the clinical and epidemiological characteristics of severe measles in infants. Methods Clinical data of 62 infants with severe measles were analyzed retrospectively.Results Of 62 infants with severe measles,42 (67.74%)were aged < 9 months,of whom 37(88.10%)were not vaccinated against measles. The onset months were February-May,41 cases (66.13%)were found in March-April.All patients had fever and skin rash,the rates of other symptoms and complications were as follows :oral leukoplakia 80.65%(n=50),Ca-tarrh symptom 77.42%(n=48),conjunctivitis 79.03%(n=49),history of choked water cough 75.81%(n=47), pneumonia 95.16%(n=59),acute laryngitis 35.48% (n=22),electrolyte disorder 20.97%(n=13),acute respir-atory distress syndrome 9.68%(n=6),liver function damage 9.68%(n=6),pneumothorax 8.06% (n=5),myo-cardial damage 4.84% (n=3),respiratory failure 3.23% (n=2),toxic encephalopathy 3.23%(n=2),measles en-cephalitis 1.61% (n= 1),and pleural effusion 1.61% (n = 1 ).Of all cases,41 cases were cured,19 cases im-proved,1 case died,and 1 case gave up treatment.Conclusion These severe measles cases occurred mainly in in-fants aged<9 months and were not vaccinated against measles;infants had history of choked water cough;the main onset months were March-April ;pneumonia was still a predominant complication of infant measles.
